Great idea. Get ready for 10,000 different views. :) I use:
- Malwarebytes, free and run it manually.
- Virusbarrier Intego free from Macapp store and run it manually.
- DetestX Swift and run it manually.
- XProtectMediator or whatever it is called.
- Lulu, Oversight, BlockBlock, Ransomewhere all I think from Objective-see.org
- CleanMyMacX > Protection > Malware Removal occasionally
- I never run any of them at same time.
