Antivirus exclusions for ARS

Hi all Our company policy is to have A/V software on all servers and I'm about to put it onto our ARS servers, but was just wondering if anyone knows of an exclusions list that's required to allow ARS to continue to function properly without A/V stopping things happening. We're already going to allow the ARS servers to send email via a policy script, but if anyone knows of a list of exclusions required, that'd be great. Thanks in advance John
