Preferences → Skip By Hash

The Skip by Hash feature enables you to exclude a specific file from subsequent scans, identified by its file hash, rather than its name or path. In MetaDefender Drive 4.4.9, the list can be managed from OPSWAT Central Management for any enrolled MetaDefender Drive. See Manage MetaDefender Drives with OPSWAT Management for enrollment instructions.

Removing an entry from the list only affects scans run after the removal. A report already generated before the entry was removed keeps its original "Skipped by hash - <reason>" entry unchanged.
