    Victim of an Illegal Activity Warning Message on startup


    I get this message on startup of Windows 8, before the login screen. Dunno if its from a virus or malware.

    Clicking OK on that brings up the login screen and I can log into Windows fine. But whether or not i log in or wait at the message, the computer will restart. I get about 2 minutes before it restarts.

    -I have done a full scan of all partitions with Kaspersky Rescue Disc 10. Found no viruses.
    -Have enabled legacy boot menu policy so can boot into safe mode by pressing F8. Message still appears and computer still restarts.
    -Unable to Refresh PC, due to drive being locked.
    -Unable to Reset PC, due to a required partition is missing.
    -I have uninstalled the graphics driver while in safe mode.
    -I have done chkdsk, found no errors.
    -System Restore Failed.
    -Cannot do a sfc scan, due to Windows Resource Protection could not start the repair service. (Running from win8 disc)

    Stumped at what to try next

    Your computer is infected. Follow the steps in the malware forum.

    Could be a variant of metropolitan police nasty.

    Malwarebytes will probably do the job.

    If you can't stay in windows, try this:

    boot into safe mode.

    Open regedit

    go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

    It should be "Shell"="explorer.exe"

    If it says anything else, that is the nasty thing.

    Change the entry to explorer.exe. Try deleting the nasty it was pointing at.

    Now see if you can boot in ok.

    Had a look in the registry where you suggested. It explorer.exe for Shell. I took a screenshot, but before i could paste it in paint, pc rebooted.

    IMHO, not knowing how deep that thing has infected - a restore (if you can you get to a restore point) or better still clean install may be better options... good luck though!

    Tried Reset and Refresh PC, both can't do. And no recovery Disc's. If i can get the PC to stop crashing, I can make recovery disc's and try install of them. But been unable to prevent the crash. Don't know what is using the file scssifilter64.sys to disable it or uninstall.

    Managed to get a screenshot of the Winlogon in the registry.
