If you keep your activity limited to legit, known sites, and even well-known, reputed "illegal" sites, you don't need a Windows antivirus in 2022. Has been the case since late 2019/early 2020 or even earlier.
Use good browsers (FF for e.g.) and uBlock Origin while browsing.
Do not plug in storage drives outside of your family or ones belonging to really malware-aware person.
Use common sense. And you know something is wrong when something is way too cheap in an ad or there are too many women with horn in your area.
(If you absolutely want to spend some money then get Quick Heal. Or get MalwareBytes.)
Windows Defender is enough. Enable recommended settings.
(I use Windows only when I need PowerPoint. But I do (free) IT of some people that have Windows.)
