When does my license key expire? Updated September 30, 2017 11:30 You can find the number of days remaining for ZoneAlarm Extreme Security, ZoneAlarm Pro Antivirus+Firewall and ZoneAlarm Pro Firewall in the program. Open ZoneAlarm by double clicking the 'Z' icon in the system tray in the lower right hand corner of your screen or the ZoneAlarm Security shortcut icon on your desktop. In Windows 7 the icon may not be visible, you will need to click on the arrow pointing up in the system tray to see the 'Z' icon. When ZoneAlarm is open you can see the number of days remaining in the lower right hand corner of ZoneAlarm and it will say how many days you have left in green or red colored text.
