Do you run antivirus on your Windows servers?
Yes, although for the most part they are configured to scan for viruses overnight with real-time file protection disabled, the exceptions are:
- File servers - Set to scan on write only. Full nightly scan.
- Sharepoint - No current anti-virus, waiting on Sophos for SharePoint to come out of beta.
- Exchange - Exchange specific anti-virus soloution. Overnight scans exclude data stores.
- Application Servers - SQL Data stores excluded from overnight scans.
- AD/DC/DHCP - Overnight scan set to exclude service specific data files and logs
This sums up my opinion.
