You prove to trully be the ignorant one. It IS possible to hide suck malicious code in such extentions as avi, mpeg, mpg, mp3, and swf (yes flash). Authors can hide such macros that arent specifically file-type dependant, but are triggerd by the media you chose to play it with. Meaning if you put a large piece of code aimed at an exploit found in winamp, and WMPlayer plays the file--chances are you wont be influenced by the code. Where as if you use winamp, the code now designed for winamp is being executed..

Think before you speak, and know what you ar talking about. You're obviously a layman without all the facts, so please stick to the topic and have ALL the information.
