NoTrax

NoTrax is an Internet browser that leaves no record of Internet activity on your computer. It is a program very simple to install and use.

The interface is very friendly and keeps the standard distribution of other top-brand browsers. You will be amazed about how cleanly this application runs: without leaving ANY trace at all on your system, just like a good portable program. Therefore, after a browsing session it erases every possible track with secure deletion methods: cookies, history files, session files and the browser’s cache.
Forget about worrying about registry keys or information on your hard drive
It's a 100% stand-alone program, it does not run on top of any other browser.
The cache is encrypted using Blowfish Encryption and Favorites are stored in an encrypted format. NoTrax supports SSL (Secure Socket Layer) and TLS (Transport Layer Security), does not run spyware, JavaScript or ActiveX, and includes an automatic shutdown option during inactivity or scheduled settings.
NoTrax is compatible with Win 95, 98, 2000, ME, NT, XP and Vista. It is only available in English.
