Microsoft is now getting into the anti-virus business for the Mac. While I’ve run virus software on Windows PCs in the past, I’ve never run it on the Mac. Every time this question comes up, I get emails asking for advice. Notably, Windows switchers often feel like they are doing something wrong if they don’t have virus software, so I can see why Microsoft could see former Windows users wanting to bring familiar virus software to their Macs.

Everyone has to make their own decisions, but I can tell you that when I was running anti-virus software on a Windows PC, it was maddening. It almost felt like the virus software became a sort-of virus all on its own. Everyone has to make their own decisions on this, but I don’t see myself installing Microsoft anti-virus software on my Mac any time soon.
