    After noticing an avalanche of malware of my laptop and attempting to fix it, I managed to remove most of it expect a vundo trojan.

    Running your "Read Me" cleaning procedures, Malwarebytes Anti-malware detects the trojan but fails to remove it even after reboot.

    Please help. I attached the appropriate logs.

    You Malwarebytes log shows that you took no action. Run it again, update, and do a new scan. Make sure you fix anything found before saving the log. Then attach the new log.

    Also ComboFix did not run properly. Either it was out of date or you had some protection software running that forced it into Reduced Functionality Mode. Delete the ComboFix.exe file that you now have on your Desktop. Then download and save the below one on your Desktop. Do not run it yet.

    combofix.exe

    Uninstall the below software:
    J2SE Runtime Environment 5.0 Update 6
    Java 2 Runtime Environment, SE v1.4.2_03
    Spybot - Search & Destroy 1.4

    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:

    O2 - BHO: (no name) - {AB429F7A-29BD-4281-B88B-2F38198FF7CA} - c:\windows\system32\dubalis.dll
    O20 - Winlogon Notify: xlvaxewc - C:\WINDOWS\SYSTEM32\dubalis.dll
    O23 - Service: Viewpoint Manager Service - Unknown owner - C:\Program Files\Viewpoint\Common\ViewpointService.exe (file missing)

    After clicking Fix, exit HJT.

    Now we need to use ComboFix to remove a bunch of malware files.
    • 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 has expired or need to be updated to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • 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.

    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

    Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    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!
