Why was Anti-Ransomware not installed in ZoneAlarm Extreme Security Updated May 31, 2019 19:05 The reason why Anti-Ransomware was not installed is because during installation of ZoneAlarm Extreme we encountered an error. Instead of stopping your installation and leaving your PC unprotected we continued to install the rest of ZoneAlarm Extreme Security.
