    Hi, I recently ran combofix to get rid of some malware issues. However, after it finished, "rundll32.exe" was quarantined alongside it's false malware counterpart "rundll32 .exe." I came across another thread with instructions on how to unquarantine, but it didn't work, and I'm still stuck. Now, I can't access any of the control panel, firewall, or anything as they all require rundll32. How can i unquarantine the files without unquarantining the malware? I have the newest version of combofix, and here are my combofix log files, and the quarantine log file

    You will need to follow all the instructions here:

    READ & RUN ME FIRST. Malware Removal Guide

    In the meantime,

    * 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::
    
    DeQuarantine::
    C:\Qoobox\Quarantine\C\Documents and Settings\Admin\rundll32.exe
    
    FCopy::
    c:\windows\ServicePackFiles\i386\explorer.exe | c:\windows\explorer.exe
    c:\windows\$NtServicePackUninstall$\wscntfy.exe | c:\windows\System32\wscntfy.exe
    C\Documents and Settings\Admin\rundll32.exe | C:\WINDOWS\system32\rundll32.exe
    RenV::
    c:\program files\AVG\AVG9\avgtray .exe
    c:\program files\Creative\Software Update 3\softauto .exe
    c:\program files\Diskeeper Corporation\Diskeeper\dkicon .exe
    c:\program files\DivX\DivX Update\divxupdate .exe
    c:\program files\Logitech\Logitech WebCam Software\lws .exe
    c:\program files\PeerBlock\peerblock .exe
    c:\program files\RocketDock\rocketdock .exe
    c:\program files\SUPERAntiSpyware\superantispyware .exe
    c:\windows\system32\config\systemprofile\Desktop\rundll32 .exe
    
    AtJob::
    
    File::
    c:\program files\internet explorer\wmpscfgs.exe
    c:\windows\system32\w.exe
    c:\windows\system32\8921.exe
    
    Registry::
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
    "vilemorumi"=-
    
    [-HKEY_LOCAL_MACHINE\software\microsoft\shared tools\msconfig\startupreg\vilemorumi]
    
    * 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 (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:
    * SAS and MBAM
    * C:\ComboFix.txt
    * C:\MGlogs.zip

    Thanks for the response, but I ended up formatting and reinstalling windows. I couldn't get all the malware off, and it seemed like the safest thing to do. But, again, thanks!
