    hello mates, :major

    I think my computer has swine flu.

    I was on the internet the other day when Mcafee told me it had blocked a couple of trojans but nothing seemed out of the ordinary until the next day.

    A windows update icon appeared and I installed it but it never went away. I installed it 3 times but it keeps reapearing. A multicoloured windows icon also apeared that says your computer may be infected with malware. A popup comes up that says i need to download antispyware software and i cant do anything but click "get antispyware software"; a setup program for PCAntiMalware comes up which I close.

    I proceeded to scan with mcafee which wouldnt scan. I also tried to do a system restore (I dont know if that was the right thing to do when you have a bug?) but that wouldn't work either. I then found and followed this guide. I couldn't install SUPERAnitSpyware so i scanned with Malwarebytes and ComboFix. After that i was able to install and scan with SAS and then i ran MGTools

    I was doing the scans in safe mode and noticed when i booted in normal mode i would get a blue screen after about 10 seconds of logging onto an account. That issued seems to be resolved now but internet pages randomly change and i have these bloody advertisments for antispyware software and the windows icons that wont go away!

    Please help

    cheers

    It looks like you did not allow MGTools to run to completion as the runkeys log was virtually empty and there was also a log missing.

    First:
    Run this: Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    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:
    NOTE: HJT may popup an error about the AppInit_DLLs line. Ignore it and click OK to continue.

    After clicking Fix, exit HJT.

    Now let's 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 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::

    [-HKEY_LOCAL_MACHINE\System\ControlSet002\Services\ovfsthxtqsntjcx]
    
    
    * 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 download and install:
    Java Runtime 6

    Now run Ccleaner to clean out only temp files and nothing else!

    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!

    Hello TimW

    Thanks for all the help! Everything seems to be working now. No more blue popup screens or windows icons. My computer does seem to be starting up a little slower after this issue though. It may be unrelated

    I'm attaching my logs. I tried to turn off McAfee before running ComboFix but it kept coming back up in the middle of the process and ComboFix gave me a message telling me to turn off McAfee. I hope this didn't mess anything up.

    Anyways things seem to be working better so thanks again for the help, mate. :major

    Please use windows explorer to find and delete:
    c:\documents and settings\Amber\Start Menu\Programs\Startup\
    e2e671aa9de9dfdaf665b0b7909b83a9.1.dll.lnk

    Your slowness is probably related to running McAfee with only this amount of RAM:
    Total Physical Memory 512.00 MB
    Available Physical Memory 136.25 MB

    Let me know if you have any additional issues.
