hi, I use ccleaner to clean up cache's and registry, then you can use eraser to wipe the empty (supposedly) space on hard drive. This will get everything that has been deleted. Download both for free at pcworld.com
Reply:There are different drive cleaners but I wouldn't bet on any of them, I think the best way to get rid of anything permanently on your C drive is to completely reformat your system.
