Title: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 25, 2013, 06:59:02 PM
Seeking your professional assistance.
I have a computer run by windows xp SP2 which used to be sluggish recently.
I installed avast free two days ago, ran a full system scan and
came up with the following viruses:
C:/RECYCLER/...../80000000.@ [trj]
C:/RECYCLER/...../800000cb.@ [rtk]
....../spywarestrike.exe

I deleted them all and spywarestrike.exe never showed up again,
yet avast keeps poping up a small window every couple of minutes
( specially when computer is online) saying it's re-blocked 80000000.@
and 800000cb.@ on a process called svchost.exe and no further action
is required. Only a couple of minutes and everything recurs.



I've done a lot of search and found numerous solutions but 've tried none yet.
Finally, I decided to take step by step advice from here under your supervision.

For whoever who would kindly help me, I'd like him to know that
I've come by this article about zeroaccess removal at  http://malwaretips.com/blogs/zeroaccess-sirefef-virus/
and I was about to procede through the steps ( which seemed very simillar to me to the procedure offered everywhere) as it requires no removable media or booting CDs.
I've also checked your procedure for simillar problems and have two problems with it:
At the moment, I've run out of removable flash drives( required for farbar recovery scan tool)
Also I'm having a problem with the lens on my cd- rom ( so won't be able to burn a CD with OTLPENet.exe)
My computer is running an OEM version of windows ( so apparently I don't have any boot CDs)

That being said, I wonder if someone would help me with the procedure in that article I've found or modify the procedure stated here to suit me for the moment.
I'd gratefully appreciate any help offered and I'm sorry for such a long post.

If you are able to boot the computer then there is no need for removable media

Download OTL (http://oldtimer.geekstogo.com/OTL.exe)  to your Desktop

Thank you essexboy for your reply.
Please forgive my computer illiteracy but what do you mean by being able to boot the computer?
Does it mean removing and reinstalling windows? As I won't be able to do so for I don't have a windows CD at all. or you mean rebooting ( restarting)?
Also shall I begin with OTL directly or go through the whole procedure at
 http://forum.avast.com/index.php?topic=53253.0
One last thing, I'd like to know your opinion of the procedure stated in the link I posted. Shall I go through it?

Many thanks

No as the malware has changed since that was written

By boot the computer I mean are you able to run windows normally (apart from the alerts that is)  If so then download OTL from the link I provided and follow the instructions to generate the analysis log.  Attach the log to this thread and we will then kill the blighter together :)

Thank you Essexboy for your patience and instructions.
I've run OTL as you told me to.But it saved only one log named OTL.txt.
You'll find it attached.

I've also noticed a few wierd things during the scan:

I've set all the parameters as  shown in the picture in your first post, yet I noticed the "standard registry" option altered to "all" while scanning and then returned to "safelist".

Also towards the end of the scan, suddenly everything stopped and a black pop-up window opened ( seems like a command window) saying C:/ documents and settings/.......     and dissapeared after a few seconds
Is all of this normal?

once more thank you :)

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 25, 2013, 10:38:57 PM
Fine, I'll follow your instructions.
Just a few questions:
Would I lose any data or files during or after running this fix? Even if infected?

3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

What reboot do you mean? Will I reboot after combofix finishes?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 25, 2013, 10:51:20 PM
No all your files will remain intact.   Once combofix has finished it's work it will reboot the computer for you automatically.  If you receive  errors about programmes being marked for deletion  then reboot the computer to clear that

Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 25, 2013, 11:50:10 PM
sorry for bothering you every now and then, just wanted to make sure about a few things: :-\

You've willingly unchecked "all users", "LOP check", "Purity check" before running the fix? right?
Also will I uncheck them for the quick scan too, or keep them checked as the very first scan?

One more thing, after running the quick OTL scan. Will it be safe to log onto the internet to download combofix?
that's because I feel that the trojan becomes activated or maybe what's called " trying to connect to a certain remote server" whenever I'm online, just wondering?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 05:29:15 AM
HELPPP
I got a frozen screen of my desktop while running combo fix.
It downloaded the recovery cosole,created a restore point and said that it was scanning for viruses which would take no more than 10 minutes.
I left it overnight, slept besides it and woke up to find it all froxen. Even the blinking "-" at the bottom of the command box won't blink anymore .
I tried the MOVE the mouse cursor but it didn't ever respond, yet I made sure that I didn't CLICK on anything.
I've read that combofix would result in unexpected results if run wrongly, so is this the case here?
What shall I do?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 09:50:39 AM
Anybody there? Please help me.
It's almost 12 hours since running combofix and getting everything frozen like a still picture.
I don't want to take any action with cmbofix without supervision. So please help me as soon as you get to see my posts.

Post by: Jackiee on June 26, 2013, 04:10:50 PM

It's been 20 hours, yet nobody suggests any sort of solution.
Is it unrepairable? Will I be hanged this way forever?
I've no means of contact with Essexboy, and all I could reach is that he's been offline all the time.
I wonder if any administrator could reach for him...could anybody respond...?

Hi reboot the computer using the power button

Then run a fresh OTL scan so that I can see what remains

Sorry about that I had to do some actual work today :)

Press run scan and that should reveal anything that combofix missed
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 05:14:29 PM
It's ok. I'm glad you came back anyway.
I'm running it at the moment, meanwhile I want to let you learn about a few things:
1- I checked " all users", " LOP", "Purity" for this scan i'm running now, just as the very first one  I'd run.
2- I saw the black screen of the recovery console on reboot this time.
3- There seems to be a folder called Qoobox in my C:/ drive now, shall I look for any logs there?
4- There's also a copy of " my computer" called "combofix" in C:/ drive
5- This time after the reboot a message came from the tray saying that I was insecure and I had my firewalls turned off, is it dangerous?
 
I know it's a lot of things, but just wanted to make sure it's ok.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 05:18:34 PM
Once done we will hide the recovery console until you need it (hopefully never)

Qoobox is where combfix quarantines the bad boys

We will check the firewall next, is it just the windows one ?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 05:30:12 PM
yes, I think it's the windows firewall, shall I have any others?

Here I attached the log from the OTL scan of today and you'll find also the one after the running the fix yesterday together with that of the quick scan before running combofix.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 05:35:44 PM
Looks good, can you confirm that the avast alerts have ceased ?

Lets now look at the firewall

Download and run farbar service scanner (http://download.bleepingcomputer.com/farbar/FSS.exe)

(http://i1224.photobucket.com/albums/ee362/Essexboy3/Farbar/FSS-1.jpg)

Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 05:40:54 PM
Yes, they've ceased since the very first scan run by OTL yesterday, even along going online no alerts or pop-ups since then. ( previously I couldn't get online without those alerts poping every couple of minutes that I disconnected the cable most of the time)

Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 05:42:15 PM
Good so it is now repair time :)
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 06:00:09 PM
Glad to hear it's good.  :D But for you, it wouldn't have been so.  :)
here's farbar's log...

I want to tell you that I've been having some difficulty since yesterday, after runing the OTL fix, making me unable to download anything, even a few megabytes, without being stopped at the 95% point exactly and getting a message in a window saying that whatsoever I was downloading couldn't be downloaded because the operation timed out.
Yesterday I tried downloading Combofix about 6 or 7 times and getting to the same cut end. In the last time I went clicking continously on the download window at the 95% point and then it completed and I got the file at last.

Today, the same exact story happened with Farbar and was resolved in the same way.
I'm sorry for such a long story, but I want to know if it's something to do with the either the infection or the fix.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 07:19:51 PM
OK we will need to run combofix one more time, this time it should run smoothly

Run combofix and allow it to update if it asks

The problems may be due to the shared access registry file being deleted by the malware, this time combofix should repair it 
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 08:34:30 PM
It's been running for more than 30 minutes now, but hadn't stopped like before.
It's scanning the machine while "-" is still blinking and the screen seems responsive.
I'm afraid it could freeze the same way as before if left to run to long, any advice ?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 09:09:13 PM
Ok, here we go back to zero point.
Combofix has made everything freeze like it did yesterday.
It seems that you are offline, anyway I'll wait for a couple of hours in case you replied.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 09:55:06 PM
OK reboot again and we will try a different fix

I will just create a registry fix for it

Yep the wife has let me have the computer back :)
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 11:04:46 PM
here are both logs
I renamed the old OTL log so that it may not be overwritten, so this the most recent.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 11:07:49 PM
OK could you confirm the firewall is now working ... Next how is the computer behaving what problems still remain

I will look at the latest log now whilst you let me know
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 26, 2013, 11:20:56 PM
ok, first almost all the toolbars in IE went black before the fix. Now everything is normally back.
As for the firewalls, I can no longer see the red balloon in the tray, so most likely it's working.
I may also mention that till the very moment, IE becomes unbearably sluggish the first time I run it after the reboot. Eventually it becomes "not responding" , I'd have to end the process manually and start all over again.
This has been the same for weeks, maybe months, and until now.

As for combofix, I doubt that it'd been corrupted during  download because I don't find a reason for the "freeze" it causes whenever run. Shall I redownload it? Is it crucial to use it with my infection? Could the computer ever get 100% clean once more without running it?

finally a big thank you :)

Oh I forgot to tell you that since yesterday, a new pale icon appeared on the desktop named "Thumb.db"
I've seen it before, a couple of months ago, thought it was just an old unused icon and deleted it.
Is it an important file or just a part of the infection?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 11:26:42 PM
Nope we don't need combofix now :) 

Thumbs is a system file and I will rehide them when we are done (it will be recreated after deletion so no problem)

Lets see if we can sus out the net speed next

This will reset the internet connections, I will just need the fix.txt that pops up when it finishes .. No need to run another scan

During this run several black boxes will popup and disappear :)

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
Code: [Select]
:Commands
[CREATERESTOREPOINT]

:Files
ipconfig /flushdns /c
ipconfig /release /c
ipconfig /renew /c
netsh winsock reset catalog /c

[Reboot]

Post by: Jackiee on June 26, 2013, 11:42:37 PM
here's the fix log
This time the computer didn't reboot and I didn't restart it manually, is this ok?
Also since first running combofix and till the momnent IE settings have been altered, it's no longer my default browser and it keeps asking about it, this's also fine, right?

By the way, I wanted to tell you that all the previous fix logs weren't saved to the desktop as the scan logs and I had to manually copy and paste them.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 26, 2013, 11:48:26 PM
Yes accept the default for IE ..

Reboot the computer now and try out the internet, let me know if there is a difference

I will be going off line soon but will be back tomorrow dinnertime :)

Post by: Jackiee on June 27, 2013, 12:16:16 AM
Thank you, Essexboy for your time and effort. :) I beieve I made you stay till late.
 As for the internet, it seems fairly better, still slow on the first launch but managable. I'll try it more tomorrow and I let you know about everything.

Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 04:05:25 PM
I'm baaaack :)

Yep let me know the result as we will have a big download for you to do soon..... SP3
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 05:14:18 PM
I'm sorry, couldn't get to see the post earlier. :$
And I'm all ready for trustworthy instructions.

As for the computer performance,

IE is still slow that I had to end the process manually the first time it launched.
But I don't care much about it as long as the machine's clean. Maybe it's the connection or my RAMs in need for an upgrade, but hopefully not because of some malware running its processes in the background.

No more alerts have shown up, neither of the firewalls nor from avast (except for being updated).

" thumbs.db " has vanished from the desktop.

I think everything else is ok.

And here I am, ready for today's work. :)

Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 05:17:26 PM
OK first we will try it the easy way

Go to windows updates and see if you are offered SP3 if so accept it

Microsoft Windows Update (http://windowsupdate.microsoft.com)

If not let me know and I will give the direct download
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 05:31:31 PM
one question please,
is it safe to go onto the internet with some other equipment hooked to the same router?
Or it could act as a bridge for the infection to pass to other devices?

Also 3 or 4 toolbars in IE browser went black while one other toolbar went transparent that I can see the desktop through it.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 05:32:53 PM
That is a lot of toolbars .. Do you need them all ?

Do you mean a second computer/phone using the router ?  If so no problem
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 05:40:47 PM
Avast toolbar is the transparent one, while the others being the menu bar, the favourites and bookmarks bar, and that last bar with tools, home . print menues.

If any of these is unneccessary, then no need for them. Exept for the favourites and history which I do need frequently.

And yes I mean other tablets, receivers and stuff like that, is it dangerous?

Post by: Jackiee on June 27, 2013, 05:46:38 PM
Microsoft wants me to install activeX control so as to view their website...is it safe?
shall I install it? or I'd search in the windows update center in "start" menu instead?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 05:50:16 PM
Allow the active x as your current one is a tad old :)

There is no problem with the other devices using the router, one thing we have not yet done is clear any remaining adware.  We will do that once the rest is done.  That may ease the connection problems

Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 05:59:07 PM
installed... then shall I choose custom or express?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 06:07:21 PM
Go for custom :)
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 07:09:28 PM
I picked custom and it kept checking for ages, more than 40 minutes maybe an hour.
I tried to close it but it wouldn't close, ended the process and started all over again.

Is there another way to go?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 07:35:19 PM
When was the last time that you updated windows ?

Lets check there is no adware remaining and I will give the direct link to SP3

CLEAR THE BAD TOOLBARS

Download AdwCleaner from here (http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner) to your desktop
Run AdwCleaner and select Delete

(https://dl.dropbox.com/u/73555776/AdwCleaner.GIF)

Once done it will ask to reboot, allow this
On reboot a log will be produced please attach that


SP3 Download   http://www.microsoft.com/en-gb/download/details.aspx?id=24

Post by: Jackiee on June 27, 2013, 08:06:32 PM
I beilive I hadn't attempted to update the windows till last year.
When I downloaded SP3 last year, some problem appeared with the internet connection that I couldn't run the web browser.

I contacted my internet provider and he claimed it was because of updating a non-purchased (OEM) copy of windows.
So, I restored the computer to a point before the the SP3 download and everything seemed to be resolved.

But since then I never thought of making any more updates. Actually, I got afraid of it. :) :)

We will do a cleanup and defrag towards the end, after the SP install as that creates some fragmentation of the drive

Is it downloading OK ?

Operation timed out at first, redownloaded it but seems to take a long while: 1 hour 15 minutes remaining.

Maybe I should get a download manager.

By the way, they offered me these also but I didn't get them:
Cumulative Security Update for Internet Explorer 8 for Windows XP (KB2618444)

Post by: essexboy on June 27, 2013, 10:16:32 PM
SP3 should cover those for you.  When you install Leechget use the custom install in case it comes with a toolbar...  I fact I will install it to check the functions

I got LeechGet and am trying to download through it.

I'd like to know what are those tasks that I pick a number of them in the download window?
it'd make 3 tasks but i made them only one...
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 10:22:19 PM
I got a full installation as it seemed customized to fit IE...
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 27, 2013, 10:35:54 PM
OK no bad stuff with it :)

The number of tasks is the concurrent downloads, what it does is split the download into say 3 parts and downloads them at the same time.  At the end it puts it all back together again so it should only take one third as long
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 27, 2013, 10:58:41 PM
Then I should have picked the highest number.... :(

The day is almost done, yet I couldn't finish a single task...

Post by: Jackiee on June 28, 2013, 12:52:38 PM
At last...it's downloaded...hopefully all of it. <sigh>
I tried to open it but I don't know the right program to.

I've attached a screeenshot of the browser, could the toolbar part be normal like that?
Would it be better to install another browser, I have Safari installation pack for example.

I can't find the words to thank yopu properly, Essexboy.  :) I'm full of gratidude that I can't express.
You've cast away the malware and now trying to improve my computer's performance ... how commendable you are.

Just double click the file as it is an exe and should run

We will reset IE to defaults next
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on June 28, 2013, 03:04:13 PM
I did, but it opened an "open with" window to choose a program.
I don't think it's an .exe, it says it's a self-extracting cabinet.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on June 28, 2013, 06:01:21 PM
Intriguing I have just downloaded it as an exe file ?  I will put it in my dropbox for you and post the link as soon as it has done

Meanwhile

Run Avast
Select Browser Cleanup
Select IE
Select restore to defaults
Does that clear the toolbar problem

Thanks to you, it's, at least, 4x faster after resetting from the control panel.

Also tried with avast and it says: Clean, excluding highly rated add ons.

I'll give it another try with update.microsoft.com, maybe it'd check faster now.

Hello Essexboy, I hope you still remember me and my problem, which you solved. :)
I tried to get SP3 from microsoft several times. All of which would stop unexpectedly saying "can not copy file blastcln.exe please retry or change the location and put ( Windows XP System Files ) in the drive you specify".
I tried to change the path to C:\WINDOWS\SYSTEM32\blastcln.exe, but all in vein. I also searched for it and found over 30 dublicates in the results for mainly 3 locations: SYSTEM32, Service Pack Files and Software Distribution but none was of any use.

Shall I correct the path otherwise or just give up and install the downloaded version?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on July 21, 2013, 04:41:43 PM
That is part of the windows malicious software removal tool.  Try an install of the downloaded version

My apologies for the delay on this but I had a dead system on another forum that my student was trying to resuscitate....  We won :)

As it stands this is an unusual error

From control panel > add/remove
Tick the show updates box
Locate and uninstall KB833330
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on July 22, 2013, 12:03:54 AM
It's all Ok. I'm glad you won and I'm sure you'll always do.

I searched a lot for that specific number but never found it. There are lots of numbered updates, which I can list in a text file if you wish, but KB833330 is not one of them.

Could you run the MSFixit on this page and see if it fixes the problem   http://support.microsoft.com/kb/949377
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on July 23, 2013, 04:11:39 PM
I tried and I got the same window with the same error. The installation wizard asked me every time if I wanted to continue the setup without copying that file and I refused.

Shall I ignore the problem and continue without it? Or shall I manually copy and paste Blastcln.exe in the service pack files?

Could there be a problem with the permissions and settings of this file? as Avast has repeatedly reported it in the results report after complete scans.
Title: Re: Please help, got stuck with a Trojan and a rootkit

If you cancel does it progress to the next file ?

If I clicked "yes" (continue without copying the file), I think it would.
Title: Re: Please help, got stuck with a Trojan and a rootkit

Post by: Jackiee on July 23, 2013, 07:30:21 PM
Fine I did. I hit "Run" and it says "no enough disk space for file expansion".
I've previously emptied more than 3 GB before I first run it and now it's only about 600 MB. Seems that it has been extracted every time I tried to run it to fix the problem, which is more than 5 times till now.

Is there a way to clear the space it filled for no use? if yes, what's the path and location?
Should I go for a system restore?

I do apologize for all the trouble I exhaust you with, Essexboy.
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on July 23, 2013, 08:50:50 PM
Not a problem :)  Lets clear some space first

1.From the Start button menu, choose All Programs→Accessories→System Tools→Disk Cleanup.
2.When it opens check all options
3.Click OK

When done the window will close

Let me know if that clears enough space
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: Jackiee on July 25, 2013, 08:29:39 PM
After reboot, I got my disk space back, did the cleanup but not to the end and ran SP3.

I ignored blastcln copying and now it's installed. When it restarted the computer after the install, it asked about automatic updates and I turned them on.

So, is everything OK till now? Shall we check blastcln.exe and copy it manually?
Title: Re: Please help, got stuck with a Trojan and a rootkit
Post by: essexboy on July 25, 2013, 08:32:49 PM
No blastcln is related to SP1 nad is no longer relevant to XP

How is the computer behaving now ?
