Ok, this is really simple and a lot of ppl dont think about it. Download any file you want , BUT...before you ever open it or try to play it, scan it with virus detector. I use avg (not tryin to plug em), so when i d/l ANY file, i right click on the file, scan with avg. I have found many viruses this way and NOT ONE has affected me because of the way I do it. Like I said, simple.
