I was downloading some movies off of limewire. I double clicked on one and media player said that the extension and the filetype wasn't the same but it would try and play it if I wanted it to. Well, I said yes and boom! Basically, it has rendered all media players useless. I ran bit defender and it found the virus but couldn't clean it...not even in safe mode. It tells me that the NT kernel has been changed. Any ideas on how to fix this? I'm running Windows Vista Home Premium. Thanks!
