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.

Useless I have paid for the next generation product for up to5 machines. I have installed it on 2, I have installed it on a 3rd machine and it is showing a trial version. I have contacted Live Chat, that was as much use as a chocolate teacup. Problem not solved. I gave up in the end.

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.

This company have lost their way. This company have lost their way. They used to provide a firewall product which allowed you to control individual programs and an AV which was light and efficient. However, the software is now just a page of "It's fine, don't worry about it" and "would you like fries with that?" On uninstalling, the company really shows its new colours... There are literally hundreds of registry entries which are not removed. So unfortunately ZA has just gone the way of the other big dodgy AV companies... What they seem to fail to realise is that what they now offer is far worse than the built-in Windows services, with no benefits. Avoid.

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!
