Surf the Internet Anonymously using a Proxy Server.

An anonymous proxy server is a special kind of
proxy loaded with software that erases your IP
address from any page requests and substitutes
its own. When the page is sent back by the Web
server, the proxy server then forwards it along to
you free of any additional software scripts that
might compromise your identity.
The most popular kind of anonymous proxy
servers are Web-based proxies. All you have to do
is go to the Web site of the proxy service, enter
the desired URL in a special address box and the
service will relay the request to the Web server
anonymously.

There are some downsides to anonymous proxy
servers. Because each incoming and outgoing
page needs to be processed by the proxy server,
this can often result in slow page loading times.
And since the proxy server attempts to delete or
bypass any suspicious elements on the returning
Web page, a lot of pages will load with errors.
Make sure that you use a recognized Web proxy
with a clear privacy policy. There have been cases
of malicious hackers who have set up phony
anonymous Web proxies to collect information
from unwitting clients. When you use a proxy
server, the information often travels unencrypted,
allowing hackers to see things like usernames,
passwords and other sensitive information.
You should also avoid so-called "open proxies."
These are proxy servers that claim to have been
abandoned and accidentally left "open" for one
reason or another. Many of these proxies are
booby traps set up by malicious hackers who
want to steal personally identifiable information.
Some open proxies are actually living on the
computers of unwitting users who have been
infected by a computer virus.
