I doubt it's a virus, unless the video is the virus (new run files you
aren't expecting).

Assuming it's a legit file you are expecting:
Save it to the hard drive. Does it run properly? If not, the problem is the
software it uses to playback.

Sometimes when I get a video by email the computer logs off when I try to
play the video. Is this a computer problem or is it a virus? How can I fix
it? Any help would be most appreciated.
