What Anti-Virus scanning exclusions should be considered for system and servers ?

Source


Consider the following file scanning exceptions for your Anti-Virus software where applicable:

NOTE: The %systemroot% is normally the C:\WINDOWS or C:\WINNT directory depending on your OS.
NOTE: the %systemroot% variable will not work as an exclusion for some OSs.  So make sure to spell out full path in your exclusion files (GPO or via AntiVirus Server)

1.) %systemroot%\System32\Spool (and all the sub-folders and files)
2.) %systemroot%\SoftwareDistribution\Datastore
Refer to the following article for information:
KB822158 - Virus scanning recommendations for computers that are running Windows Server 2003, Windows 2000, or Windows XP http://support.microsoft.com/kb/822158
3.) Any Network Drives that are mapped.

   you will need local administrator privileges, and the firewall needs to allow access
   to enable firewall access, run this command on target machines:
   netsh firewall set service type = remoteadmin mode = enable
.EXAMPLE
   Get-NonstandardService
   lists services with nonstandard accounts on local machine
.EXAMPLE
   Get-NonstandardService -computername 10.10.10.33
   lists services with nonstandard accounts on remote machine with IP 10.10.10.33
.EXAMPLE
   Get-NonstandardService -computername 10.10.10.33, 127.0.0.1, serv12-1, client3
   lists services with nonstandard accounts on four machines (including local system)
