This great piece of free open source software turns any internet connection into a fully secured internet connection, so now you can do your internetbanking safely in a cybercafé. The package included Portable Firefox, so you can even use the best browser around instead of the browser that happens to be installed. Finally, with the default options, all your tracks are cleared after stopping Torpark.

According to the download site: Download TorPark for your language, and put it on a USB Flash keychain. Plug it into any internet terminal whether at home, school, or public. Run Torpark.exe and it will launch a Tor circuit connection, which creates an encrypted tunnel from your computer indirectly to a Tor exit computer, giving the appearance of having the Tor exit computer's IP.
