I'd have to reiterate:
I'd enable virus checking on my firewall

I've heard of cases where the CEO mailed
everyone in the company a copy of the Concept

I won't name company names... ahem.

1. Filtering all of the viruses all of the time is impossible.
2. Filtering some of the viruses most of the time is possible.
3. Filtering some of the viruses most of the time is better than
filtering none of the viruses none of the time.
4. Encrypted data and self-extracting binaries complicates/confounds the
5. User education, desktop and NOS based virus checking are still
required, because many (the majority?) viruses come from floppies and
the filtering of network data is imperfect.
