Well.. rapidshare are just files uploaded by other people.. So there is still the same chance of a virus as if it is from any other file sharing site. And usually torrents are safe, you just have to be smart with it.. if you're going to download torrents, get them from thepiratebay.org and go by the torrents that have the most positive feedback and seeders/leechers. I wouldn't suggest downloading any torrents from rapidshare, i dont' trust the people.
