I use my Mac in an environment full of Windows machines. I’m always careful online, but I also have GAD and I’d like to add a layer of security for some peace of mind. What I’m looking for is an anti-malware software that doesn’t constantly run in the background and that I could just launch once in a while for a quick scan of the machine. I see that BitDefender has an antivirus on the App Store. Is it any good?
