    We are finding Virut with most of the AVG Win32/Heur. I'd like you to do the following before we go any further:

    • Make sure to use Internet Explorer for this
    • Please go to VirSCAN.org FREE on-line scan service
    • Copy and paste the following file path into the "Suspicious files to scan" box on the top of the page:
      • c:\windows\system32\userinit.exe
    • Click on the Upload button
    • If a pop-up appears saying the file has been scanned already, please select the ReScan button.
    • Once the Scan is completed, click on the "Copy to Clipboard" button. This will copy the link of the report into the Clipboard.
    • Paste the contents of the Clipboard in your next reply.
    Also scan these,

    C:\WINDOWS\explorer.exe
    C:\WINDOWS\System32\svchost.exe


    Before trying to run any programs, it's better to confirm- or not as soon as possible

    Virut is a Polymorphic File Infector that infects ..exe, .scr, .rar, .zip, .htm, .html. Because there are a number of bugs in its code, it may create executable files that are corrupted beyond repair resulting in an inoperative machine.
    It opens a Backdoor by connecting to a predefined IRC Server and waits for commands from the remote attacker


    Good explanation here:
    http://miekiemoes.blogspot.com/2009/02/virut-and-other-file-infectors-throwing.html


    Change all of your passwords and monitor any online transactions.

    I will know mroe when I see the log.

    That's good news! Now you go back to the beginning.

    Please follow that steps in our Virus and Malware Removal thread HERE.

    Be sure to check the lines in both Malwarebytes and Superantispyware to remove the entries they find.
    don't remove anything in HijackThis yet- we'll help with that.

    It would also be helpful to know what system problems you're having and what operating system you're using.

    When you have finished, please lattach the logs to your next reply. They wi;ll be reviewed to find and remove the source of the malware.
