Hi,

I'm looking for opinions & advice on running Anti-Virus software on Windows
2000/2003 servers.

I'd always suggested running AV software (such as Sophos' products) on file
servers and e-mail servers, but have recently come across a scenario with a
customer server that was labouring badly with high CPU usage. Although an AV
product on the server wasn't the main culprit, when looking at ways to
reduce CPU usage (as an upgrade was unlikely) I considered that incorrectly
running an AV package on a file server might unnecessarily increase disk and
CPU usage when checking every file it reads.

Is there a best practice for AV on file servers? As long as a specific
Server version of a vendors AV package is used, is this ok? What downsides
if someone installed a standard desktop AV package on a server by accident -
would this severely impair server performance whilst it AV checked every
file it dealt with for LAN users? Even when running AV on the client
desktop, is it still prudent to have AV on the file server?

Any thoughts and opinions welcome.

Regards,

Richard Tubb.
