Do the Mac AV applications also scan for Windows virus definitions? I've never actually had AV on one of my Macs so I'm not sure what that does.
That was what the Solaris thing was all about, but all my machines are database servers and users don't directly attach and there's no file sharing.
those are the only viruses they do find as there are none for OSX ... some IT depts make it mandatory if people want to network with the PC computers
