Really??  I'm amazed.  Do you have a URL?  I don't know anyone who
runs A/V software on Linux unless it's to scan for Windows viruses.

Except that running as non-root on Linux isn't quite as constraining as
not having admin privileges on a Windows box.

Well, I hope Joe User won't run as root more than necessary, but
you're right; education is required.  The modern Linux distros are
pretty good about forcing you to create a non-root account and
recommending that you use it.

A 98%-secure Linux box is a lot less restrictive than a 98%-secure Windows
box, because Linux has fewer design flaws that need working around.

Not running A/V software on a Linux box is no risk at all.  Even the
McAffee A/V software wouldn't detect a worm in time to do any good.
You can take the following simple precautions (which I do):  Mount /tmp
noexec, and if you're really paranoid, mount /home noexec also.  That
pretty much kills any propagation vector for viruses.
