The various members on here will have different recommendations based on their own experiences, but I've been using the free version of
Comodo Internet Security for around 8 -10 years with no complaints. I've installed it on all 3 computers in my household and none of them have ever been infected or hacked, so why pay for something else?

Best of all, it's free - - I don't believe in paying for internet security anyhow - - most are a rip-off when it comes to subscription-renewal, especially Norton.
