    You need to tell me exactly what Sophos is detecting.

    * Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    o If it is not on your Desktop, the below will not work.
    * Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    
    File::
    c:\windows\Tasks\lhiwcaoe.job
    c:\windows\system32\efcDTNeC.dll
    
    Registry::
    [-HKEY_LOCAL_MACHINE\software\Classes\CLSID\{86C510E9-97EF-4749-914F-0280247BE3A6}]
    
    
    * 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.
    If it asks you to overide the prvevious file with the same name, click YES.
    * 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.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Combo.

    Hi Tim. Thanks a lot for helping me out. I really appreciate the help available here, especially since I have not had any luck fixing the Vundo problem since it started.

    Here are the two logs you requested. I will run a sophos scan right now and see if anything comes up.

    After you do that:

    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:
    NOTE: HJT may popup an error about the AppInit_DLLs line. Ignore it and click OK to continue.

    After clicking Fix, exit HJT.

    Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Now use windows explorer to find and delete:
    C:\temp\EXT37558

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Sophos.

    I did the Sophos scan before the steps in your last post. I have attached the log which found Troj/Virtum-Gen. I believe the other thing that Sophos found was actually ComboFix.

    Your logs look clean, but we can check to see if the things SOphos detected are still there:

    Now download The Avenger by Swandog469, and save it to your Desktop.

    * Extract avenger.exe from the Zip file and save it to your desktop
    * Run avenger.exe by double-clicking on it.
    * Do not change any check box options!!
    * Copy everything in the Quote box below, and paste it into the Input script here: part of the window:

    * Now click the Execute button.
    * Click Yes to the prompt to confirm you want to execute.
    * Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    * Your PC should reboot, if not, reboot it yourself.
    * A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.

    Tell me what issues you still have.

    As long as they are in quarantine there is nothing to worry about.

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They are useful as backup scanners. 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" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.

      • Delete the C:\combofix folder from combofix (if it exists)

    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. 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.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.

    8. After doing the above, you should work thru the below link:
