Asking about anti-virus on an Apple-specific Forum is like waving a red flag in front of a bull - I celebrate your chutzpah!
There will always be die-hard Macolytes who insist MacOS is impervious and doesn't need it (largely based on their experience from when the OS was a fractional piece of the marketplace), and those who may have come from Windows, and feel that any AV is just required because Stuff Happens.
MacOS's marketshare is significantly higher than it once was and has become an attractive target, especially as the internet and emails open up more opportunities to cause havoc - and especially to those who still think they're impervious. Apple has been good about applying patches (sorry...'updates') as security issues have come to the fore - but not always proactively. Plus, while some issues may not be able to affect Macs directly, there is every possibility that the Mac can be a conduit from which users can inadvertently pass on problems to others - through documents, hyperlinks, etc the user forwards from other sources.
It is for that reason - as I work with individuals and companies running on a selection of OSs / apps of various vintages, trade information back and forth, and do research online as part of my work - that I have an AV on my Mac. A bit of a 'Belt and Suspenders' move, just in case. Being a good IT citizen, as it were.
That said, there are some AV / Malware / Clean up app manufacturers out there whose products are not, ahem...all that they should be, or as well-written as they could be. I agree that badly-written AV apps can drag down performance - but that's hardly just the purview of this kind of app.
And because of that - and the red flag nature of discussing Mac AV with fellow users, I usually suggest to folks who ask me about AV on Macs to check the responses on Forums like this one, but also definitely explore two 3rd Party testing sites that aren't beholden to any manufacturer or advertiser.
These are AV Comparatives (https://www.av-comparatives.org/consumer/test-results/macos/) and AVTest (https://www.av-test.org/en/antivirus/home-macos/).
And, for what's it's worth, I'm currently using BitDefender for Mac. And the occasional use of the free version Malwarebytes.
