I think you've got something there.  I've been struggling with the load 
on my MS boxes too.  Until now, I was running with both F-Prot and 
ClamAV.  The idea being that if one scanner was slow with a new virus 
update the other would catch it.  After reading your message I turned 
off ClamAV.  Today the queues were really short and keeping up with the 
load was easy.  We process approx one million messages/day.  Thanks for 
the tip!  It was not apparent to me while monitoring the system that it 
was the virus scanning that was causing the delay.
