What to happens to ZoneAlarm when my license expires? Updated September 30, 2017 11:36 When you purchase ZoneAlarm Extreme Security, ZoneAlarm Pro Antivirus+Firewall or ZoneAlarm Pro Firewall you receive one or two years of online technical support, Antivirus updates and free upgrades to the software. Once the license expires, there is a subscription renewal cost to continue receiving product updates, Antivirus updates and technical support. If you do not renew your license, ZoneAlarm will continue to work and protect your computer as a basic firewall only and you will not be able to get any support for the product. (other features and functions may stop working and updating) beyond the license expiration date. You can renew through this link http://www.ZoneAlarm.com/renew/ Note-We highly recommend updating your subscription for your ZoneAlarm product each year. It is important to continue to stay ahead of hackers with the latest in security.
