ok, my computer has been working just fine until the time i found out a HUGE chunk of my memory was gone. i havent downloaded anything big enough to take up 20GB and my add/remove programs didnt show anything either. i thought i had a virus so i ran a virus check, but when i ran it it was searching through about 600,000 .TMP files with random names like "3nfkdc74" and such. it didnt find a virus but the check took a day and a half. i looked at the place where all the files where found at and there was nothing in the folder!! im pretty sure that wherever these files are at is taking up a large amount of my space and are hidden... ive been deleting files so my computer would shutup about the "low disk space" and then it just gets full of more of these .TMP files!! i really need some help...
