You have two choices:
1) You can download TOR. It will change your IP address, and also encrypt your connection
(like when you go to your bank online, and you see that LOCK symbol on the address bar, which means NO ONE can see what you're doing).
TOR is free and isn't controlled by any government or corporation so you truly get privacy, BUT - you have to use the TOR browser.
2)OR you can buy VPN from Avast. It costs about $36 per year currently. BUT YOU GET TO USE YOUR OWN BROWSER.
