From discussions with the anti-virus vendors during various crises over the 
years, I've learned that the real-time scans are optimized for speed, while 
the scheduled scans are focused on thoroughness.  This means, disturbingly, 
that malware can elude the real-time scan, yet be caught by the more-thorough 
scheduled scan.  Hence the anti-virus vendors continued recommendations to run 
weekly scheduled local scans on all computers.

Subject: Do we still need scheduled scan?

If we have already implemented virus scan at the gateway, on the mail 
server, on individual servers, and real time scan on workstations/laptops, 
do we still need scheduled, e.g., weekly, scan on workstations and laptops 
as well as servers?

Schdeuled scans really slow down some machines.

Any comments are appreciated.

Thanks,

Doug
