I just found out most of my AVI(anime movies) stored in my harddrive( now are something different. They are either now can't be played because "not avi files" or the contents of movies are something else (very strange, this movies stores another movie content) although the files names and size are still the same like before. I swear to god that i have played those movies before and didn't encounter any problem. I didn't know exactly when this happened. Recently my Norton caught a virus named bd.exe in my computer twice. Do you guys what is the cause of problem..how can i fix it? Thank you in advance! Addtional Info 120Gmaxtor, VIA Controller Soyo Mobo Dragon Lite 2.4P4, 1 Maxtor ATA 133 for other hard drives. The one having problem hooked directly to MOBO

..more info, other movies stored on other hard drives don't have that problems. And the contents of the strange but playable movies are some of the deleted VOB movies files. I copied those from other hard drive, which used Maxtor ATA 133 card.
