    A certain folder, where all possibly infected objects are placed, which were detected during scans or by real-time protection.

    With further scans of Quarantine, the status of the object may change. For example, the object may be identified as infected and can be processed using an updated database. Otherwise, the object could be assigned the not infected status, and then restored.

    If you manually move to Quarantine a file that turns out to be not infected at the next scan, its status changes to OK only if the file has been scanned for three days after it had been moved to Quarantine, or later.

  • Terminate – interrupt the application from running.
