    I haven't been able to beat this one on my own and have exhausted my skill set at this point. I followed the directions and am attaching the logs. Of note, when combofix rebooted, the virus scanner (avira) reinitialized so I dont know if it interfered. Definately saw root kit activity, including avira deleting a root kit .sys file.

    This is a friends computer I am working on and it does not have live internet access at the moment. (The ISP turned off her connection saying that her IP address - not wifi, btw - was transmitting continous spam mail for male enlargement products).


    Thanks in advance for your help and time!

    You have spybot search and destroy's teatimer feature active which I will need for you to disable otherwise it will hinder the fix.

    How to disable Spybot's TeaTimer

    Did you knowingly install the below program? If not then please uninstall it

    • WinPcap 4.0.2

    If you did not deliberately set this proxy yourself then please include it in the HJT fix below:
    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:

    After clicking Fix exit HJT.

    Now we need to use ComboFix
    • 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::
    
    File::
    C:\WINDOWS\system32\drivers\yvfxsj.sys
    c:\windows\Kfukeditexetedab.dat
    c:\windows\Akehisigihaj.bin
    C:\Windows\0.log
    
    DirLook::
    c:\documents and settings\Micron\Local Settings\Application Data\{9856A3CF-C50A-4DA8-A23A-5F4631A3E3D8}
    C:\Documents and Settings\All Users\Application Data\{74D08EB8-01D1-4BAE-91E3-F30C1B031AC6}
    
    Folder::
    c:\documents and settings\Micron\Local Settings\Application Data\vurrrxdct
    C:\Documents and Settings\LocalService\Local Settings\Application Data\ytgcxkuqj
    C:\Documents and Settings\Micron\Local Settings\Application Data\jmxrvpfu
    
    Registry::
    [HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run-]
    "MSMSGS"=-
    [HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run-]
    "Microsoft Windows Support Center"=-
    "msghandler"=-
    "yahgamreg"=-
    "SpiralFrog"=-
    [-HKEY_LOCAL_MACHINE\System\ControlSet001\Services\yvfxsj]
    
    • 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

      [​IMG]

    • 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.

    Let me know how things are running!!
