I also use a VPN now. You can see the one I use at proxy.sh
It's only $40.00 a year and from what I understand it will secure your data from it's server's to your pc and your ISP only see that there is data, but will not know what the data is. It's important if you get a VPN that you get one that is headquartered where they aren't afraid of the US government and won't give into it like all the US companies we are hearing of.
I also use the TOR browser found at
www.torproject.org
This browser bounces you around a bunch of relays and mixes you in with other users so no one knows who is searching or looking at what.
Then on my mobile phone along with my VPN from proxy.sh I use orbot which is from guardianproject.info this will put me in the same relay network as the tor project. Then I use the orweb browser for my phone also from guardianproject.info. You can find the mobile apps on google play, but guardianproject says the some have put up fake links in google play so that your browsing won't be secure. It's best to follow the links to google play from their website or download it direct from them.
