When an alert is raised, it appears in McAfee Network Security Manager (Manager) in an unacknowledged state. Unacknowledged means that you have not officially recognized its presence by marking it acknowledged. An alert remains in an unacknowledged state until you either acknowledge it or delete it. Unacknowledged alerts display in the Unacknowledged Alert Summary section of the Home page and in the Real-Time Threat Analyzer. Acknowledging alerts dismisses them from these views. Acknowledged alerts display only in the Historical Threat Analyzer and in reports. .
