For anyone interested in trying to secure greater online privacy, look at this page from the Electronic Frontier Foundation (EFF) --
https://ssd.eff.org/tech. The Tor browser bundle mentioned on that page lets one surf anonymously, though some suspect a government might have been responsible for a recent attack on Tor and which apparently harvested some IP addresses.

I haven't used it because I assume everything online can be harvested by the government.
