Like I said, this is by definition the difference between a virus and a
worm. But once on a system, viruses (including this one) *do* have
mechanisms to spread automatically.

Yep -- and *if* people follow good practices on any OS (assuming the OS
lets them do so in practice), viruses are a limited threat overall. But even
that limited threat is a real threat that shouldn't be ignored -- *and* we
need to do better to make it easier for non-technical users to follow best
practices and still get work done.
