    Hi all,

    i have a machine (vista 32bit) that a colleague had a whole bunch of nasties on it. eg. trojan.zefarch, trojan.gen, trojan.fakeAV!gen42, univirex.

    These were detected, quarantined, and deleted by symantec.

    i followed all of the steps in http://forums.majorgeeks.com/showthread.php?t=35407

    attached are logs for SuperAS, MalwareAB, and comboFix.
    SuperAS found 2 other pieces of malware.
    MalwareAB found nothing.
    ComboFix rebooted the machine half way through then upon completion - after reboot - a symantec window opened and said it had quarantined bloodhound.malPE. I had symantec disabled!

    Now everytime i try to launch an application - and i'm trying to run rootrepeal now - i get a window pop up that says "illegal operation attempted on a registry key that has been marked for deletion" i get the same message whether i try to launch firefox, symantec, skype etc.

    advice greatly appreciated.

    logs attached.

    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.

    We still need the C:\MGLogs.zip

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

    * 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 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:\Users\Erin\AppData\Local\p0v7l40rnkd86e02b68p1cx330p3n05q44abi7381b
    C:\Users\Erin\AppData\Local\Uyubequ.dat
    C:\Users\Erin\AppData\Local\xcbm74r48dyj7cru65v883r3xhg11m1h2qt0g
    C:\Users\Erin\AppData\Roaming\Microsoft\Windows\Templates\p0v7l40rnkd86e02b68p1cx330p3n05q44abi7381b"
    C:\Users\Erin\AppData\Roaming\Microsoft\Windows\Templates\xcbm74r48dyj7cru65v883r3xhg11m1h2qt0g
    C:\ProgramData\p0v7l40rnkd86e02b68p1cx330p3n05q44abi7381b
    C:\ProgramData\xcbm74r48dyj7cru65v883r3xhg11m1h2qt0g
    
    
    * 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 previous 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.

    Note: 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.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:

    * C:\ComboFix.txt
    * C:\MGlogs.zip

    Make sure you tell me how things are working now!

    Good to know.

    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 real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    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:
