How Threat Prevention provides maximum protection when rescanning quarantined items

Prev Next

When rescanning items in the quarantine, Threat Prevention uses scan settings designed to provide maximum protection.

Tip

Best practice: Always rescan items in the quarantine before restoring them. For example, you might rescan an item after updating your protection. If the item is no longer a threat, you can restore the item to its original location and remove it from the quarantine.

Between when a threat was originally detected and the rescan performed, scanning conditions can change, which can affect the detection of quarantined items.

When rescanning quarantined items, Threat Prevention always:

  • Scans MIME-encoded files.

  • Scans compressed archive files.

  • Forces a Trellix GTI lookup on items.

  • Sets the Trellix GTI sensitivity level to Very high.

Note

A quarantine rescan might still fail to detect a threat. For example, changes to a path or registry location can produce a false negative.
