Smart Protector Pro is easy-to-use software that protects your privacy by erasing all traces of your Internet activity automatically. It completely erases your Internet Explorer history, cookies, temporary files (cache), typed URLs (drop-down address list), recent documents list, and Recycle Bin. Smart Protector also allows you to choose which items to clear and which to keep. A unique feature is the Save State/Restore State function, which allows you to save the state of your computer so no one will know you've used a program. Other features include a cookie manager, scheduling, a stealth mode, an emergency key, RealPlayer, Media Player, DivX Player, PowerDVD, and ACDSee. The program works with AOL and MSN browsers.

Version 3.9.3 features minor improvements and bug fixes.
