Worst software product out there. It keeps sending packets of my data to an IP address in Israel. After I installed it my computer would get very slow because it was using all of the system resources. Then the icing on the cake was that someone from Israel starting accessing my email account and I got alerts from Google that my pc was infected. All after I installed Zone Alarm from Check Point. Very High Risk software. Very Suspicious activity from Check Point software. Do not trust them, they are like cyber criminals. Look at all the bed reviews on here for Zone Alarm, wish I had read them before downloading their horrible software.

Computer crashing nagware
I used their free firewall for years without problems. However this year they decided to change it to nagware, with a popup advert every time I started my computer. No major problem you might think, except every day the nagware caused my computer to completely freeze and need to be restarted wasting valuable time. So I uninstalled and changed to a non-nagware firewall and problem solved, no more freezing computer.

Zone Alarm is pure fraud
Zone Alarm is pure fraud. Be careful. They come with your mobile phone contract as a free trial, sneak the charges into your monthly phone bill by sneaking a clause into the contract that you need to call your provider to cancel.

pure hell
The worst ive ever counterend.
I just reinstalled my system and trough it was a good idea to protect it with zonealarm. a tech blog said it was the nr 1.
It looks poor, options would not adjust, get spammed with all sorts of warnings of legit software with no advice ready and UAC prompts. support account website loops me back to it. can't delete the program trough the uninstaller. can't kill the processes, can't deleted the folder on the C drive. Can't get any update.
Yeah, what else is there to say

ZoneAlarm destroyed my PCs net for a month, and blocked System Restore
I was effectively unable to use my Win7 PC for anything internet related - downloads, streaming, basic browsing, gaming - for over a month. Connection to the internet would be slow and drop every 10 seconds or so, meaning webpages wouldn't load properly, and anything requiring a sustained connection was no longer possible.
It came after a standard Redistributable C++ windows update. There was no indication that this was an issue stemming from ZoneAlarm. I tried disabling the ZoneAlarm services early on as a possible solution, along with my Avast firewall, but this didnt work. System Restore wasn't working. A month down the line, out of pocket from numerous tech support options and seemingly having exhausted every possible cause, I decided that it must simply be a case of "Old PC, needs an overhaul" and was literally in the process of buying Windows 10 Pro, when I decided to try and clear my new-ish SSD for the install. I noticed that some difficult to delete security files had copied themselves to my SSD in the short time I'd had it installed, and realised that these were related to ZoneAlarm's anti-ransomware service. A forum online had previously told me to leave these alone as they are important and harmless (big mistake), but I knew they were on my HDD anyway so found out how to delete them properly. After unistalling the anti-ransomware program (a convoluted task in itself) I tested my net and for the first time in over a month, it was working smoothly. It appeared that ZoneAlarm did not like the C++ update and had decide to choke my PC in response.
In all this time, there had been no ZoneAlarm update whatsoever. It beggars belief that there would be no response from them since I imagine I can't be/have been the only one that this issue has affected.
If it had not been a free program then I would certainly be asking for compensation right about now. Much of my personal and professional life relies on a stable internet connection and it pains me to think of the time, money and effort I've spent trying to circumvent this stupid issue.
I've replaced the software with a more trusted provider.

It kept freezing my browsers and it stops me from making and receiving skype calls
Its security is way too paranoid that it make internet surfing a hell of an experience. It slows down my connection and it kept freezing my browser tabs. It also blocks skype! Embedded videos on forums, You cannot play them neither.

Badly Programed!

Good program if it did not fill up your hard drive with Sandblast files.
This just has NOT been thought through at all, it is a badly thought through piece of software!
Dont install it unless you have at least a 1TB hard drive!!!

Disgraceful at self-updating
Product seems ok at firewall and anti-virus functions. It has an ongoing massive problem doing its own updates. They freeze at 0% or get to 100% and then 'error'. The usual chat support solution is to uninstall it and reinstall, or that the version you are running it out of date and a fresh install is needed - can't even self-update when that happens and there is no proper notification of it. I have used this product for many years and have been in contact with support dozens and dozens of times to resolve the constant update problems. I end up wasting inordinate amounts of time fixing the program (uninstall, clean, reinstall and then re-register) because of it. Going to another brand now as fed up.
