Security notifications are designed to let you know the status of your security. You will see a security notification for one of two reasons:
Blocked Application Notification: An application that has been launched from your machine has been blocked in accordance with rules that you have set.
Security Alert Notification: There has been an attack launched against your machine, and this notification will either simply inform you of the situation or provide instructions on how to deal with it.
You may see notification messages above your system tray icon from time to time. They indicate that your system has blocked traffic that you have specified as not trusted. Please note that if you are operating under Block All mode, you will see these messages quite often. On the other hand, if you are operating in Allow All mode, you won't see any notifications at all.
If these notifications start annoying you, you can either click Do not show this window again, or you can disable these messages altogether in the Options window, under the General Tab.
