:) That's right, or was when I last administered AV for Macs. Strangely
enough, the Dr Solomon's Mac product that McAfee acquired but ran down did,
IIRC, detect BSVs, but that function was never migrated to Virex. And
F-Secure used to have something that detected macro viruses (not Mac native
malware) on Macs , though I don't think it ever got got past beta. Of
course, I'm old and feeble, and may have misremembered some of this stuff.

Most Windows AV doesn't check for Mac stuff, though most detect some *n*x
stuff. But some of the vendors with a Mac product do, or did. Sophos and
Symantec used to, and probably still do, but it's a while since I needed to
check these things.
