Editorial Review of Tor
A surprising amount of information about you can be gathered as
you surf the Web--including the operating system you use, the sites
you've visited recently, your geographic location, and possibly
your company (based on your IP address).
To keep these pieces of information private, try Tor, a free
program that protects your anonymity as you surf. Tor takes all of
your Internet communications, including instant messaging and other
Internet applications, and sends them around a large network of
"onion" routers that are Tor servers, making it impossible for
sites or people to invade your privacy.
The Tor download includes other software that you need for
maintaining your privacy--notably Privoxy, a proxy program. The
programs work well together; and because the software
self-configures, they are simple to use. Tor runs in your system
tray. To become anonymous, right-click the icon and choose Start.
From that point on, you'll be anonymous. To stop surfing
anonymously, right-click again and choose Stop. You can even change
your Tor identity for maximum cloaking.
Note: This program is donationware. It is free to try,
but the author accepts and encourages donations towards further
development.

Description of Tor
When you browse the Web, your life is an open book. Web sites can track your online activities, know what operating system and browser you're running, find out your machine name, uncover the last sites you've visited, examine your history list, delve into your cache, examine your IP address and use that to learn basic information about you such as your geographic location--and there's more as well.
How to protect yourself? Use Tor, which protects you anonymity as you surf and use the Internet. When you use Tor, all your communications, (not just Web surfing, but also instant messaging and other applications) are essence bounced around a giant network of Tor servers called "onion routers," until it's impossible for sites or people to be able to track your activities.
When you download Tor, you get other software that works in concert with it, including Privoxy, a proxy program. All the software is self-configuring, so you won't need to muck around with port settings or the like. Tor runs as a small icon in your system tray. To start Tor, right-click it and choose Start from the menu that appears; to stop it, right-click it and choose Stop. Once it starts, simply use the Internet as you normally would. If you're somewhat paranoid, you can regularly change your Tor "identity," to make it even harder for anyone to track your travels. Tor also includes a nice bandwidth tool that graphs your bandwidth use.
