For anti-virus on the Mac, I like MalwareBytes. It's the only one left that both scores well on the annual shootouts and also has relatively low hit on CPU performance. My employer uses Crowdstrike. However, I prefer to prevent malware rather than deal with it after-the-fact, and that's where the tools from Objective-See come into play -- LuLu, BlockBlock, KnockKnock, Oversight, etc.... So, I like a belt-and-suspenders approach, where you run the Objective-See software and also MalwareBytes. And then periodically use CleanMyMac to do other system maintenance activities.
