  1. Hi, 1st post and am asking questions.
    Forgive me if this is a stupid question, but I'm not very up on os stuff.
    On startup , my friends computer gets the following message:


    The NTVDM CPU has encountered an illegal instruction.

    cs053c ip:b587 op : ff ff ff ff
    Choose close to terminate window.

    And a seperate window which says:
    Error reading reg 678.dll
    Module not found

    As far as I know, he hasn't installed anything recently.
    Is it something picked up from the net, virus,etc?

    What would it be affecting.
    Is there anything that can be done to fix this?

    All help gratefully received.
    Thanks in advance,

    You can check your registry at HKLM\Software\Microsoft\Windows\CurrentVersion\Run and see ifyou have anything pointing to that executable. Removing it should make the error go away from startup if it's there. As far as what it is I'm not sure - I haven't had a chance to look it up, but if I get some time maybe I will tonight.

    Sounds like a virus to me. Mysterious executables unknowningly tacked onto the startup menu is a very questionable thing....

    I strongly suggest running a virus scan on your computer.

    In the mean time, you can delete this reference by going to Start / All Programs / Startup and right clicking on the shortcut listed for this particular EXE file. Then delete it. This should get rid of the error; unless of course, this is a virus and it insists on keeping that file in the startup group. It will probably regenerate the shortcut.

    Right so I installed AVG free edition on his computer.
    It now seems to be infested with luvbug viruses
    which avg alerts you to after startup, and advises a full scan.
    When I did the scan, it found nothing.
    Ran a luvbug detector and remedy, but it detected nothing.
    Any ideas?

    oh and thanks for recomendations thus far, much appreciated!
