True.  As I have no windows boxes on the LAN I only run it manually, and it 
wasn't done on the day that that reported.  The one area that I am vulnerable 
to is email-borne viruses, and since I am not serving those to windows boxes 
it is only out of curiosity that I need clamav.

I'm sure there are plenty of people that can give Ralph detailed information 
about using it efficiently.  I was merely demonstrating how easy it is to show 
that you keep the database up to date.  You are quite right,of course, they 
will want to see evidence that it is scanning as well.
