If Auto-Protect scanning is enabled and you update definitions at hourly intervals or less (using Rapid Release or LiveUpdate), disable at least one of the following Auto-Protect features on the servers that have a message store:
Scans > Auto-Protect: Enable Background Scanning
Scans > Auto-Protect: On virus definitions update, force rescan before allowing access to the Information Store
When both of these options are enabled, the message store is rescanned each time definitions are updated. If you update definitions at hourly intervals or less, this can affect overall mail throughput.
