The scan results 'skipped clean" and "skipped dirty" are returned when a file's hash matches a hash that has been whitelisted or blacklisted, respectively. Whitelisting and blacklisting allows MetaDefender Core administrators to eliminate false negatives/positives without waiting for engine vendors to update their detection definitions.
In MetaDefender Core v3, the feature is only available through the MetaDefender Core CLI. Whitelists and blacklists will be available through the MetaDefender Core Management Console in MetaDefender Core v4.
