Well, latley I've been loosing My gb without downloading anything. Afew weeks ago I lost 3, and then yesterday I lost another 3. Can anyone tell me how to fix all of this?

Empty recyle bin, norton protected. Temp folders...

you hdd have a badsector and you may to lowlevel fomat it and then delet all tempfiles i yyour windows or what ever you install

Begin by ignoring the advice given by faisal9555. You have given no information to suggest bad sectors. To suggest deleting all temp files after a low-level format only demonstrates this persons lack of knowledge (you'd have nothing on the drive at all after a low-level format). Your problem could be caused by a number of different things. Firstly, I'd suggest following the advice given by Nan. Empty the recycle bin, temp files, Temporary Internet files, etc. Secondly, do a complete system scan for both viruses and spyware. Please let us know if you found someone's advice to be helpful.

I'll keep plugging it because it's so useful......IMHO of course ! http://www.win.tue.nl/sequoiaview/ See at a glance EXACTLY where all your Gb's are gone.

Well I did a virus scan..Nothing came up.. ((Thats when I used AVG)) And then afew hours later without scanning like.. 6 viruses came up with my EzAntivirus thing which I deleted except for to becuse they could not be removed.. But my GB stayed the same. I did spyware I found alot of stuff on there which all seemed normal exept for something called "Dyfuca" I had never seen that before except for afew viral pop up things. So once again I removed all things in my Spyware/adware thing and my Gb stayed the same..
