I looked at Tom's Hardware
www.tomsguide.com/best-picks/best-mac-antivirus and they rank Bit Defender, Kaspersky and Norton 360 as first, second and third.
Last time I drove all the way to Fry's to get Kaspersky, because they're the ones that outed Stuxnet. But it's really hard to find. So I think I'll go with Norton. $25/year and it has a password manager and VPN.
There is already malware
recompiled to run on the M1 chip.
