Clean your own house first

from here and here

I realize that Microsoft Defender is a lot better than MSAV was, and that it may even be good enough for PCs, but I don't think it's reached the point of making PCs safer than Macs yet.

In addition to that, I have difficulty imagining most Mac owners using an antivirus at all, never mind one by the makers of Windows. Many Mac owners joke that Windows IS a virus.

Maybe some day MS Defender for Macs will make sense, but not before they clean up their reputation and their own platform.
