I recommend it. It's possible that a workstation could be infected prior
to the release of an update that includes that virus signature. I've
noticed that the real-time scan will sometimes not detect what's present
on the file system without a full disk scan.

Some real-time scans can be throttled down to use only a percent of
available resources, i.e. processor and disk time, so the scan could
goes unnoticed by the end user. Without this, the virus software will
often utilize nearly 90% of available resources, and that's what will
slow the system down. I believe McAfee has this feature.

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
