Your McAfee software reports critical protection problems as soon as it detects them. When a critical protection problem is detected, a notification is displayed in the protection status area on the McAfee. Critical protection problems are directly related to the critical protection features: Real-Time Scanning, Updates, Personal Firewall, and Subscription. If a critical protection problem occurs, it compromises your PC’s security and changes the protection status to “at risk” until you fix the problem.
Working with alerts
Alerts appear on your screen to let you know when security events occur on your PC. An alert provides information about an event, as well as recommendations and options for resolving security problems. You can also control which alerts appear (for example, you can hide informational alerts), and decide if the McAfee splash screen appears on startup. Since alerts are an important part of your McAfee protection, you cannot disable them.
