Malware Woes (Vundo?)

    My girlfriend's laptop has become infected with the .sdn version of Virtumonde (Vundo) and it locked it down with some fake Security Center screen. I don't know what may have caused it since once I was able to bypass the fake screen and check history for IE, I didn't find anything out of the ordinary. I've tried the basic cleaning methods, but no luck since it still shows up on Spybot SnD.

    The cleaning methods have restored the computer's functionality and relieved most of the sluggishness. However, from time to time the sound from various interactive ads will play for ~10 seconds in the background and there are several instances of iexplore.exe running when IE isn't open under my control.

    Attached are the logs as instructed (I believe I've done all this correctly). Any feedback/help would be appreciated. I do not have a recovery disk for the laptop because it was lost in a move, but if this is a game over scenario, I can order one from Toshiba... but that's obviously a last resort.

    Thank you for your time.

    1. Please go to add/remove programs and uninstal the following out of date Java:

    • Java(TM) 6 Update 3

    We will install the new version a little later on, but not for now as I don't want you to reboot the machine until we have made some progress.

    2. 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:

    O4 - HKCU\..\Run: [AdobeUpdater] "C:\Program Files\Common Files\Adobe\Updater5\AdobeUpdater.exe"

    After clicking Fix exit HJT.

    3. 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::
    
    RenV::
    c:\program files\Adobe\acrotray .exe
    c:\program files\Adobe\Reader 8.0\Reader\reader_sl .exe
    c:\program files\AIM6\aim6 .exe
    c:\program files\Common Files\Adobe\Updater5\adobeupdater .exe
    c:\program files\Synaptics\SynTP\syntpenh .exe
    c:\program files\Toshiba\Bluetooth Toshiba Stack\itsecmng .exe
    c:\program files\Toshiba\FlashCards\tcrdmain .exe
    c:\program files\Toshiba\Power Saver\tpwrmain .exe
    c:\program files\Toshiba\SmoothView\smoothview .exe
    c:\program files\Toshiba\Utilities\kenotify .exe
    c:\program files\Toshiba\Utilities\svpwutil .exe
    c:\windows\System32\hkcmd .exe
    c:\windows\System32\igfxpers .exe
    c:\windows\System32\igfxtray .exe
    c:\windows\System32\ndstray .exe
    
    File::
    C:\Windows\system32\gamuloza
    c:\windows\System32\nelufuyu.exe
    
    DirLook::
    c:\users\Timshel\AppData\Local\nkccnb
    
    Registry::
    [-HKEY_LOCAL_MACHINE\software\microsoft\security center\Monitoring\SymantecAntiVirus]
    
    
    • 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

    • 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.


    4. Also delete all files in the below bold folder except ones from the current date (Windows will not let you delete the files from the current day).

    • C:\Users\Timshel\AppData\Local\temp

    5. 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 Combofix.

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

    I'm at work now so I don't have access to the logs to attach to the post, but everything is back to normal and scans are clean again. Your instructions were clear and I didn't run into any problems following them. Thanks for the help!

    Please do post the logs when you can find the time so that I can verify the files we wanted killed really are killed. Choice is yours obviously, but I am here waiting if you need me :)
