As said in the title ive got some nasty sirefef trojan in my system.. - hopefully you will help me even though I dont use Avast. I use Nod32 and it warns me about sirefef.ez, sirefef.fb etc - I´ve run several scans with Malwarebytes and Spydefender etc.
Nod32 cannot remove the problem and what it seems im not the only one when I googled this. Essexboy seems to be the man, so i beg of you to help me because I dont want to reformat my drives.
Here is logs from MWB and OTL:

Hi,
**WARNING**Unfortunately one or more of the infections I have identified are Backdoor Trojans, IRCBots or other Malware capable of stealing very important information. You need to stop using all Internet Banking sites, change passwords to all sites with sensitive information from a clean computer and phone your bank to inform them that you may be a victim of identify theft. More often than not, we advise users that a full reinstallation of their Operating System is the only way to ensure that their computer will ever be 100% clean again.
Unfortunately I have found what is known as the ZeroAccess rootkit on your system. It is an especially nasty infection that can take quite some time to clean as well as may have damaged your system files itself. As a warning, during the cleaning (if you choose to do so) you may lose internet access with this computer and in the end we may need to reinstall the operating system anyway depending on the extent of the infection.
If you would like to format and reinstall your Operating System please let me know and we can assist you with that.
If you would like to continue with the cleaning, please continue with the following instructions and I will be more than happy to help. :)
----------
Please download ERUNT (http://www.snapfiles.com/get/erunt.html) (Emergency Recovery Utility NT). This program allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed. **Remember if you are using Windows Vista as your operating system right-click the executable and Run as Administrator.

Do I have to turn off Malwarebyte and Nod32 if I´m in safe mode. (no tray icons) And I´m not sure they are running in the background - or am I wrong.
Is it safe to boot in safe mode with network turned on or is it so that I can just boot like normal?
-
Nevermind.. I ran it anyway and even though I thought it freezed at the creating log part it went ok.. - Here are the logs:

Hi,
You are running everything just fine.
Download CKScanner by [color="MAROON"]askey127[/color] from Here (http://"http://downloads.malwareremoval.com/CKScanner.exe") & save it to your Desktop. - Right-click and Run as Administrator CKScanner.exe then click Search For Files

- A message box will verify the file saved
- Double-click the CKFiles.txt icon on your desktop then attach the contents in your next reply

Hi,
CKScanner has detected illegal software on your system. Besides being illegal, it's the number one way of infecting your system as all cracked/keygen software is infected. This forum, as well as all the other malware removal forums, do not support the use of illegal software except for their removal. If I were to continue helping you with illegal software installed, it could be construed in the eyes of the law as aiding and abetting a crime.
This may or may not be related to your computer issues, however, if you wish me to continue helping you, then you must remove both the keygen and crack files as well as the related programs. If you do not agree to this then this thread will be closed and no further help will be offered because I will never be able to tell you your malware logs are clean. Please let me know if you wish to continue.
-
I am well aware of that and what you see is an old keygen for a navigator i got on my phone some years ago.. - the other files (the one that says cracked paint etc is brushes/addons for photoshop and is nothing illegal.) The keygen is deleted and the others are not illegal.. (if not DICE has put some trojans on their installation-cds for Battlefield 2 and 2142)
-
But I can uninstall all those programs too if you´re not satisfied :'(

Ok... let's keep moving :)

Hi,
Malwarebytes
I see that you have Malwarebytes already on your computer. Please open Malwarebytes, update it and then run a Quick Scan. Save the log that is created for your next reply.
----------
Please run a free online scan with the ESET Online Scanner (http://www.eset.com/onlinescan/)
Note: You will need to use Internet Explorer for this scan[/i]- Tick the box next to YES, I accept the Terms of Use
- Click Start
- When asked, allow the ActiveX control to install
- Click Start
- Make sure that the options Remove found threats is NOT selected and the option Scan unwanted applications is selected.
- Click Scan (This scan can take several hours, so please be patient)
- If there are threats that are found, please press List of found threats and then in the next window that opens press Export to text file...
- Copy and paste/or attach that log as a reply to this topic
**Note** If not threats are found there will not be a log created.
----------
In your next reply please attach the logs made by Malwarebytes and ESET scanner. :)
-
Malwarebyte didn´t find anything, but Eset found the same as before except in other folders. (probably quarantined)
Here are the logs:
-
Yes...those are already quarantined. How is your system running?
Download Security Check by screen317 from here (http://screen317.spywareinfoforum.org/SecurityCheck.exe) or here (http://screen317.changelog.fr/SecurityCheck.exe).- Save it to your Desktop.
- Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
- A Notepad document should open automatically called checkup.txt
- Please post the contents of that document.
-
I haven´t run in normal mode since we began so I don´t really know (but safe mode is running excellent ;D ) I uninstalled old java versions before we started, so that may be why they are not up to date and i found a thread about what to do after an attack(update Java, Adobe reader etc.), so I will follow that guide.
I see two dimmed out desktop.ini- icons on my desktop but i guess that´s nothing to worry about?
Do you want me to start in normal mode?
-
Can the quarantined viruses be safely removed or are they sleeping in the system?
-
Hi,
That log looked ok. Go ahead and leave the files we found infected alone for now. We will have those removed when we clean up our tools.
Please boot to Normal Mode and give it a good run around and let me know how your system is running. :)
-
It seems to be ok, no errormessages. the only thing is Eset who says that it wants to send some files for analyzing:
"Following files seems to contain new threats. Send them to ESET for further analyze:"
File
services.exe(688)
services.exe(600)
services.exe(600)
services.exe(648)
C:\users\oskar\appdata\roaming\xsecva\xsecva.exe
services.exe(604)
C:\windows\assembly\gac\desktop.ini"
translated from swedish but i guess its something like that
Can i just send them for analyze or cancel
Could it be because we edited the files, its not a popupwarning about an active virus (i haven´t been in normal mode for like three days so it could be old. I don´t know
-
I think that ESET is picking up quarantined files.
-
OK, but where do we go from here?
-
Hi,
Download Security Check by screen317 from here (http://screen317.spywareinfoforum.org/SecurityCheck.exe) or here (http://screen317.changelog.fr/SecurityCheck.exe).- Save it to your Desktop.

Sorry for any delays. I had some technical problems with my own system and just now was able to get back. :-\
Adobe Reader
You have an older version of Adobe Reader. You can download the current version HERE (http://www.adobe.com/products/acrobat/readstep2.html)
You may want to consider Foxit Reader (http://www.foxitsoftware.com/downloads/index.php) instead. It may be a bit lighter on resources.
Visit their support forum
Foxit Forum (http://www.foxitsoftware.com/bbs/forumdisplay.php?f=3)
In either case you should uninstall Adobe Reader 9 and Adobe Reader X (10.1.0) first. Be sure to move any PDF documents to another folder first though.
----------
System still running well? :)
-
I'm not home at the moment and won't be until tuesday. My system is running fine and as you can see I've already installed Adobe reader X, but it seems old reader 9 is still in the system but not in the uninstall-list under controlpanel/ programs.. Don't really know how to uninstall it any other way.
Trouble with your own system isn't really what you need while helping others with theirs is it :o
-
My system is running fine
;D
------
Trouble with your own system isn't really what you need while helping others with theirs is it
I got it fixed up....not malware related.
--------
If you don't see Adobe Reader 9 don't worry about it.
------
Providing there are no other malware related problems...
IT APPEARS THAT YOUR LOGS ARE NOW CLEAN :D SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!! :D
This infection appears to have been cleaned, but I can not give you any absolute guarantees. As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.
----------
The following will implement some cleanup procedures as well as reset System Restore points:
Click Start > Run and copy/paste the following text into the Run box as shown and click OK.
Combofix /Uninstall
(Note: There is a space between the ..X and the /U that needs to be there.)
(http://i1224.photobucket.com/albums/ee380/jeffce74/CF.jpg)
----------
Clean up with OTL:
- Right-click and Run as Administrator OTL.exe to start the program.
- Close all other programs apart from OTL as this step will require a reboot
- On the OTL main screen, press the CLEANUP button
- Say Yes to the prompt and then allow the program to reboot your computer.
----------
Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren't cluttering up your desktop.
Here are some tips to reduce the potential for spyware infection in the future:
1. Make your Internet Explorer more secure - This can be done by following these simple instructions:
- From within Internet Explorer click on the Tools menu and then click on Options.
- Click once on the Security tab
- Click once on the Internet icon so it becomes highlighted.
- Click once on the Custom Level button.
- Change the Download signed ActiveX controls to Prompt
- Change the Download unsigned ActiveX controls to Disable
- Change the Initialize and script ActiveX controls not marked as safe to Disable
- Change the Installation of desktop items to Prompt
- Change the Launching programs and files in an IFRAME to Prompt
- Change the Navigate sub-frames across different domains to Prompt
- When all these settings have been made, click on the OK button.
- If it prompts you as to whether or not you want to save the settings, press the Yes button.
- Next press the Apply button and then the OK to exit the Internet Properties page.
2. Enable Protected Mode in Internet Explorer. This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code. To make sure this is running follow these steps:- Open Internet Explorer
- Click on Tools > Internet Options
- Press Security tab
- Select Internet zone then place check next to Enable Protected Mode if not already done
- Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
- Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.
3. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis. With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.
4. Firewall
Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly. A tutorial on firewalls can be found here[/color] (http://www.bleepingcomputer.com/forums/tutorial60.html). **There are firewalls listed in this tutorial that could be downloaded and used but I would personally only recommend using one of the following two below:
Online Armor Free (http://download.cnet.com/Online-Armor-Free/3000-10435_4-10426782.html)
Agnitum Outpost Firewall Free (http://download.cnet.com/Agnitum-Outpost-Firewall-Free/3000-10435_4-10913746.html)
5. Make sure you keep your Windows OS current. Windows XP users can visit Windows update (http://v4.windowsupdate.microsoft.com/en/default.asp) regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems. Without these you are leaving the back door open.
6. WOT (http://www.mywot.com/) (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites. WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.
7.Finally, I strongly recommend that you read TonyKlein's good advice So how did I get infected in the first place? (http://www.geekstogo.com/forum/index.php?autocom=custom&page=How_did_I)
Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.

Just two questions before I let you go:
* I´ve got these $RECYCLE.BIN with subfolders on every one of my partitions why and should I delete them/ hide them?
* Isn´t windows firewall enough for blocking attacks? ::)
As for now I can not notice any strange behavior in my computer and hope i got completely rid of the nasty trojans.
I must once again thank you Jeff "jeffce" for all the help you have given me with this big problem of mine. -Most people probably don´t understand how much time and effort you guys put in to everyones problems and I am greatful for what you have done. So great thanks from Sweden and me, Oskar
-
$RECYCLE.BIN
It is part of the file system and I would keep it. :)
-----
Isn´t windows firewall enough for blocking attacks?
There are two thoughts on this and you need to decide how you feel. Some people will tell you to use a third-party software firewall at all times. I prescribe to the thought that if you are using a wireless router at home that is secured than the Windows firewall is sufficient. If I go someplace else I do have the software to activate a third party firewall though. If you are hardwired at home than I would use the third party firewall as well.
------
I appreciate your kind words and you are more than welcome!! :)
