This a rabbit hole question! You can search online for the best security suites all day long and not find a consensus of opinion. I have tried lots of the free suites,and was not impressed.Once they are on your computer they are a pain to get rid of.AVG and McAfee especially. Over the last few years I have used Bitdefender (terrible customer svs.) but it seemed to work well. McAfee was ok,but couldn't tell what it was really doing,and it is a pain to get it GONE! Avira was nice for awhile,but way too many notifications.I recently started Kaspersky and am still getting used to it. So far I am liking it,but it doesn't play well with some of my other security. It has a VPN included,but that starts a whole new set of problems logging into Email ,etc.
It is a shame,that in this digital world we live in, that Apple and Microsoft can't seem to build a machine that doesn't need extra security! It's always about the MONEY,( that I don't have)! Ya just gotta pick your poison I guess.
