    I originally was getting notice of infection from Trojan Horse Crypt.alqw. After several attempts I finally followed the instructions here and got rid of that notification from AVG and now I have a new one. I left the computer on, but off the network over night and awoke to Trojan Horse Generic 27.BVPL in my re-installed AVG virus vault.

    Disclosure: I tried to fully remove AVG even using the AVG removal tool you provide and when I ran Combofix it still told me AVG was loaded on the system. I reloaded AVG after my all scans were done and background image finally reappeared. I thought I was clean.

    Logs attached.

    I want you to run TDSSKiller so refer to the below for how to do so.

    TDSSkiller - How to run


    Please also download MBRCheck to your desktop
    • Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
    • It will show a Black screen with some information that will contain either the below line if no problem is found:
      • Done! Press ENTER to exit...
    • Or you will see more information like below if a problem is found:
      • Found non-standard or infected MBR.
      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    • Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
    • MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    • R3 - URLSearchHook: Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)
    • O2 - BHO: (no name) - AutorunsDisabled - (no file)
    • O2 - BHO: Spybot-S&D IE Protection - {53707962-6F74-2D53-2644-206D7942484F} - (no file)
    • O9 - Extra button: (no name) - AutorunsDisabled - (no file)
    • O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)
    • O18 - Protocol: AutorunsDisabled - (no CLSID) - (no file)
    • O24 - Desktop Component 0: (no name) - (no file)

    After clicking Fix exit HJT.



    Now we need to use ComboFix by sUBs

    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    Registry::
    [HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\policies\system]
    "DisableCAD"=-
    File::
    C:\Documents and Settings\Dana\Templates\kwqvso5e2fii2ncv7fvy0w413s8v
    C:\Documents and Settings\Dana\Local Settings\Application Data\kwqvso5e2fii2ncv7fvy0w413s8v
    Folder::
    C:\Documents and Settings\Dana\Local Settings\Application Data\mlkyuxktx
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe

      http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif

    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below

    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.

    If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.


    Reboot your machine and install the most current and up to date version of Java available here at the below link:

    Java Runtime 6

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

    Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!!

    I didn't have any trouble following your instructions. However, AVG and Super Ant-Spyware restarted on reboot prior to log generation. Not sure if that is an issue.

    The final Combofix log is attached. It's been almost 20 minutes now and so far, so good. No random tab pop-ups and no warning from AVG. I'm going to leave my computer on overnight again and if there's no additional report from AVG I will consider this battle won.

    Thanks so much for your help!

    OT: Can I delete all logs once I know the issue is really at rest?

    Don't delete anything until we are finished! :)

    Do not forget this part you missed it:

    I had the computer powered for most of the night and no redirects and no AVG notification.

    MGlog is attached.

    Delete this file:

    C:\Documents and Settings\Dana\Templates\kwqvso5e2fii2ncv7fvy0w413s8v

    Reboot, navigate back to where it was, is it still gone?

    Deleted. Rebooted. Still gone.

    Happy days!!!

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:
