There are several VPN (virtual private network) services available for encrypting and anonymizing your internet connection, here I am talking about a free VPN service called proXPN (a high speed pro version has also there).
It is a very easy to use VPN service (US) which secures your existing internet connection by encrypting all user traffic tunneled via a secure gateway.
Installation and configuration of this program is quite simple. Just register a free account, then, after the installation of proXPN, enter your login details to connect the VPN service. Its performance is not bad at my end.
