I've had the same problem. But you shouldn't worry too much about any kind of virus. Just as long as you have some kind of virus protection like "AVG" which I use. Usually if a file is bad (as in harmful to your computer and in the sense that it doesn't play) I get a message telling me it is corrupt and then I immediately kill the download and empty the incomplete folder out. Hold the Ctrl button down and click all the useless incomplete files and while you're at it, empty the recycle bin too as often as possible. I really wish they'd stop putting fake files of movies (as well as music) all over the network. Most of the time the name of the video file when played had absolutely nothing to do with the subject! You might want to forget all together about trying to download real movies because they won't play and I don't know what you would need to use to play the file if it isn't compatible with your media player.
