hi!
Theoretically it's not possible, that a virus get executed while watching a movie. The same counts for any other file, which doesn't get executed (like txt-files, jpg's, bmp's, tif's, mp3's and whatever), since the processor (the player-program) does not execute the content of the file.
On the other side, the data of the file could be manipulated, so that a specific (badly coded) player, interpret the data wrong and cause a buffer overflow. This buffer overflow could be used to get the virus-code executed on the computer.
But i think the chance that someone use such a bug in a player, to get a virus executed on your computer is very very small ... i assume that's just a badly coded virus-detection routine in your antivirus program, which interpret the video-data wrong.
Cu, JNS
