AbsoluteShield Internet Eraser Pro
AbsoluteShield Internet Eraser Pro is for anyone concerned about their privacy, and who doesn't want that information available. It deletes just about any trace you can imagine of your surfing activity, and does so for multiple browsers, so that you can clean up Firefox and Internet Explorer from the same interface.
It goes well beyond browser cleanup, and also cleans up Windows itself by clearing the Recent Document List, the network cache, the Temp folder, and other locations. And it even clears lists of files used in many programs, such as Windows Media Player, WinZip, and many others.
The truly paranoid will also be pleased to know that it doesn't merely delete the traces; it "shreds" them so that they would be very hard to reconstruct.
