CCleaner is one of my most favorite software.
It will clean up many browser files from IE and Firefox like history, temp internet files, cookies, and many others with one button to click. It is totally configurable
It also has a registry cleaner to clear out junk.It also securely deletes (wipe) the recycle bin files for a maximum up 35 passes. Dept of Defense is 3 passes. Each pass overwrites the file into obliteration.You find that in Options> Settings.
It has a easy uninstallertool for unwanted software as well, much easier that windows
