From Emery Info-Engineering:
Erase information stored in Windows about Internet sites visited. This program is free (although donations are appreciated) and fully functional. It automatically runs when the computer boots, the user logs in, or browsers are closed. It works with all 32-bit Windows programs and with all major browsers (Internet Explorer, Navigator, Opera, and now AOL). It erases the cache, history, cookies, addresses, passwords, and temporary files, and closes pop-up windows in browsers, including AOL.
