My hard drive is getting eaten up.

2 month old computer running x64 vista SP1 with a 1 TB hard drive. It seems that the amount of space being used is going up.

I only have about 80 gigs of stuff on this computer (checked the program files folders and all those other folders, which totaled 80G) yet it says I’m using 198 gigs of 933 gigs. How is this possibe??? There is no way I have 198 gigs of stuff on this computer.

So what is up? Do I have a virus that is downloading tons of stuff? Is it vista related?

I got it under control. Looks like I had about 100 gigs of system restore points.
