At some point I stopped trusting anti-virus softwares for some reason. Nevertheless, I want to ask if anyone is using one on his/her Mac? Please recommend, because I got a warning today from my router's detection activity that I might have gotten worm virus ....😖

No running av, except for the Windows one.
Lots of unreachable backups, nothing new gets installed or tested on that machine, occasional malwarebytes scan.

Laptops: nothing of value too any hacker,virus.
Regular malwarebytes scan, too many Chinese/Russian apps tried.
Ready system image and bootable pen.
