Usually when d/ling music I keep the search active until I get all my music. If a file comes up corrupt I delete it, go back to the search, and extend the search just for that one song. I get as many sources as possible and the corrupt issue is usually resolved. I have never gotten "infested" by any .exe, .avi, .mp3 or any other file I have ever downloaded, but my anti virus has stopped several. Keep your AV updated and running active protection. And, sorry, but contrary to some advice I don't scan anything. I play it or whatever and if the AV catches it I note the file size and try to avoid it in the future. Know file sizes. 3,000 to 7,000 for mp3. 155 MB to 250 MB for 2 part avi and 700 MB for full length avi movies.
