most AVs are decent nowadays. you just need to make sure you don't get one that will bog down your system resources (norton is/was notorious, but i havent used it in at least a decade). I like Trend Micro, i've heard good things about Bit Defender.

i'm good with the Windows Defender (already built into Windows 7/10) and Malwarebytes combo for my home PCs. for Malwarebytes i do pay the subscription because i like the real-time scanning feature. i have a raspberry pi running DNS (Pi-Hole) at home too where i subscribe to various blacklists feeds so i'm not hitting known bad sites.
