Hi,
If you are looking to stay anonymous on internet, a vpn is the solution but not every vpn providers can assure you a true anonymity ! Honestly, I'm using NordVPN.com, they are based in Panama, where there is no US data retention laws.... so I'm sure to be safe ^^ I find them on http://www.topvpncanada.com and I'm pretty satisfied with it.. work fine and speed is great.
Cheers
