Something is wrong with my computer. I had *6.5 gigs on my hard drive and a couple of hours later my space went down to like ** gigs and i don't know how it happened. I didn't download or install anything. I formated it before because i had the same problem and i thought it would get rid of it but the same thing happened. I have norton antivirus 2004 and i did several system checks and there was no threat.
