Antivirus Quarantine
Antivirus quarantine is designed for infected items that contain important information and therefore cannot be deleted. When an item is quarantined, it is put to the /Library/Application Support/MacKeeper/Quarantine folder. It means that the viruses are removed from the system, but the files remain and can be restored from the quarantine.
On the Antivirus Quarantine pane you can view a list of all quarantined items, each of which you can restore from the quarantine or delete. Besides, you can view information about the total number of quarantined items, including individual information for viruses, trojans, and other malware. To restore the items from the quarantine, select them, and then click Restore from Quarantine.
