Newer editions of the Opera browser have built-in VPN. The VPN can access servers in 5 world locations.

This is a good solution if your only concern is what goes through your web browser. It won't help those who download torrents or use Kodi; a free entertainment software that's the next best thing to the Internet.
A person could use the Projectfreetv.x (it changes domains sometimes) website to watch tv without commercials but some kind of script and ad blocking software like Noscript (in Firefox) or adblock plus is highly recommended when using that site. As always an up to date anti-virus program should always be running. I like the free version of Avast but AVG and possibly others are likely okay.
