do i just keep restoring them & rescanning to see if they've been added to some safe file data base?
if so, how long does this take?
i'm not sure when to delete these permanantly.
No clue here as well.
In case users are sure the samples are not malicious they attach them in the
False Positive/Negative reporting - (Is this a malware that CIS has/not detected?) and in one/two days the AV database is updated.
As restoring quarantined samples to periodically check if their classification was changed might be unpractical it would make sense to add a lookup button in the quarantine dialog.
This way quarantined samples could be easily checked against the most recent AV DB updates.
