SCEP can configure scan history retention period (ScanPurgeItemsAfterDelay)
Antimalware policy cannot configure ScanPurgeItemsAfterDelay in it.

QuarantinePurgeItemsAfterDelay can be set in the policy. So let's have ScanPurgeItemsAfterDelay configurable in order to achieve full control on antimalware history management.
