The program is dated resource hog. I have a high-end specs gaming desktop I use for work but nevertheless, ZA makes it suffer. I have used ZA since 2009, but this is becoming ridiculous. UI design is super dated and hasn't been updated since 2012, despite users begging for years for optimisation and change. Stay away!

Takes 1GB of RAM and Disk at 100% I wanted to try and install the ZoneAlarm free version. They offered a free license for the ZoneAlarm Next Generation Antivirus (Beta version). After installation, it takes more than 1GB of RAM memory, the disk is at 100% and I cannot do anything on the computer. And this is impossible to uninstall. Some folders are left and CheckPoint SBA keeps running in the background and eating memorey/disk. I tried with Revo or IObit: still some folders with dll than cannot be removed. What a nighmare !!!

Do NOT install if you watch any online videos If you watch any online videos, to include YouTube, please DO NOT install ZoneAlarm. My laptop isn't fast (1.86Ghz to be exact), but I was able to watch any online videos without interruption before I installed ZoneAlarm. I did not think it was Zone Alarm that caused the issue, after all, it was only an antivirus software. I deleted Zone Alarm to test it out, and instantly, after a reboot, I was able to watch videos without interruption. The speed felt rejuvenated to youth again. Thank goodness I didn't pay for a year subscription.

Zone alarm is worse than 5 years ago… Zone alarm is worse than 5 years ago when i paid them for the service One might think that a site I have visited 10.000 times in the last 10 years might be recognised but no not even a simple google search is allowed these folks really need to pull their creative heads from the deep dark place they seem to keep them. Totally worthless in the free form thus why would i purchase the vetted version. Very irritating subset program, oh it changes for no reason from day to day also one day google is great the next day failure wake up and no accept your bs terms haha idiots

Good Software Gone Bad In the beginning, Zonealarm was a very good firewall. However, it's grown into a monster writing thousands of temporary files in less than two weeks of use on a new laptop. The ability to control installed software, from companies that poke around in your computer, under the guise that they're giving you a 'better experience' is gone. These are two major issues that have brought me to dump Zone Alarm permanently.
