If you share a computer, you can rest assured that someone has looked over your browser's history for salacious details. PrivaZer protects your privacy by cleaning that up, but it doesn't stop there. It does a thorough cleaning of everything you do on your computer, so no one can use it against you.
PrivaZer can be installed on your computer, but if you want to take the program with you, it offers an executable version you can slip on a portable drive, too. Regardless of how you run it, the first time you use the program it takes a long time to set up. You have to click through more than a half-dozen screens to actually get to the cleaning. Luckily, PrivaZer can save your settings so you only have to make the choices once. To make up for the long wait, the program does wipe any trace of what you've done with your computer. It goes from obvious places that could hide secrets, like your browser history or cookies, to places no one would ever think to look, like your Microsoft game history and older versions of Windows. For those who don't know what's safe to delete and what isn't, it offers a guided deletion process that will help.
Though you could probably delete most of these traces yourself, it would take hours. PrivaZer does it all at once and just as fast as any other registry cleaning software. It will even give your computer a noticeable speed boost in addition to protecting your privacy. If several people share your computer, there's no reason to not use this program to clean things up.
