I know this is off topic, but Windows Defender is plenty good enough. Coupled with a good ad blocker, you really don't need to be using third party AV on non-corporate PCs these days. Having good Internet hygiene does help though.

AV is mainly to save you from your own stupidity/naivety because it's incredibly unlikely you'll get a virus providing you don't open unknown email attachments or download things off of sketchy websites.

And call me paranoid, but if something did get through the cracks, I'd probably reformat anyway because I'm not going to trust AV to have completely eradicated the infection.

The big thing for me is 1) performance, defender generally eats up less performance than other AV solutions

And 2) I don’t even really trust Microsoft to scan all my files, let alone some other company. Fuck that.
