Could somebody please reccomend me a safe and reliable VPN for me to try please, preferably a free one. Perhaps if everyone could share what they use and more specifically why.

Note: Please if possible could somebody make their explanations and reasons for using this software as simple and clear as possible. I am a complete novice on this subject and I have read that some of these companies over complicate things for people with little to no knowledge (hence me asking the good members of this site).

Thanks in advance
