Torpark
Download Torpark 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, allowing you to surf the internet anonymously. How much does Torpark cost? IT'S FREE.
You may have heard about those heavily advertised second-rate software packages like Anonymizer, SafeSharing, InvisibleIP, SecretSurfer, etc. Well, not only do they charge you money and/or a subscription fee, but they are bloated and full of useless components. They also require an installation that leaves tracks on your computer. How is that anonymous? Try Torpark; its small, portable, clean, open-source, free of spyware/adware, and free.
Notice
Torpark is in English by default, but includes language packs for Arabic, German, French, and Simplified Chinese. There are about 35 unique language packs available for Torpark, and a bookmark is included in Torpark to quickly allow you to add any of these languages.
