Because the IT policy (currently) requires it. I don't agree with that
policy, but there you are - I don't have the authority to simply ignore it.

Yes, I know. But we have petabytes of file systems shared over SMB/CIFS, so
if a Windows machine inroduces something to the network, it strikes me as
reasonable that if my (still putative) FreeBSD system finds it before
another Windows system, I have potentially prevented a much wider problem.

I wouldn't waste your time wondering, if I were you. Of course they *all*
look for malware that infests Windows machines. But, that nontwithstanding,
I have to adhere to the policy, whether I like it or not.

Yes, and I am hoping that that fact is enough to persuade him that the
current policy (which he inherited, by the way, he didn't have a hand it its
establishment) is no longer applicable in an increasingly mixed environment
(Polytropon brought up the obvious matter of smartphones and tablets and
other devices).

Thanks for your thoughts.
