this is my first topic, and it's about best free vpn that I used, because I spent a lot of times searching for that and I found the answer about that;
1) Psifon3 free vpn software that hides your IP with unlimited bandwidth also it doesn't annoying you with a lot of ads like hotspot shield and you can choose from SSH, SSH+, VPN and it dosen't take much CPU or RAM in your PC so you will have good performance in your computer but its flaw that sometimes the connection get lost and you have to start it again, second software I will going to talk about is cyberghost
2) Cyber ghost it dosen't have annoying ads and it have good speed also it have good privacy and it uses SSL/TLS protocol, but it have limited bandwidth so you should not choose that software if you will downloading big files that's have big size also if you will use torrent to download big files it will not be good with cyber ghost free version, also you have to wait 1 minutes to start and every 3 hours the free version cyberghost will disconnect and you can connect again...
3) spoftflux and I think it's the best free vpn i used before because it doesn't limite the bandwidth also you can easily disable it's ads by ads block extension not like hotspot shield, so you should install all of this software and run the one you like, and i recommended spotflux for you
4) Hotspot shield it have nice speed and good privacy and you can choose an uk or us ip by choosing expert shield for uk ip or hotspot shield for us IP but it has bad ads and it's not easy to deal with that so it will be the last software in free vpn you should choose if you can't deal with this annoying ad , and if you can block the ads then it will be best vpn you should use because it have unlimited bandwidth,
5) tor browser and i know it's not vpn software but i provided it as free software that you can use to hid your IP and it's the safest software if you will understand all the instruction and articles about how to use it in the right way, but it's slowest software i have been used not like vpn speed.
