Since I installed the free firewall version my win 10 PC it hanged for a million times. It even hanged my PC when I was uninstalling it. This software should be forbidden and removed from the internet as soon as possible!

2016 version

Negative Comment by fixitmanarizona
about ZoneAlarm Free Firewall Mar 2016

i've had zonelarm for a number of years but stupidly "upgraded" to the 2016 (14.something) version on my XP computer. It is NOT compatible with the AVAST antivirus I have installed, it also installs a non-compatable version of .NET and some other things like toolbars and caused me all kind of hell. System freezes, not-boot states, etc. AND good luck removing it, as it won't uninstall in safe mode!
Can no longer recommend this.
Maybe commodo instead?

Latest update installs search conduit.

Negative Comment by Kooie
about ZoneAlarm Free Firewall Nov 2011

For those who don´t know what search conduit is, it´s a piece of garbage which replaces your default search provider (google, yahoo, bing..) for their website (search.conduit.com).
Latest upgrade of ZoneAlarm doesn´t improve security of the app, it just installs a toolbar (in my case in Firefox), you can disable and remove it, but the damage is done and it´s no easy to 100% remove it from your system.

Has a good pedigree, but I've found the latest builds to be a little heavy on the system resources (I was running it on older workstations), and opted for either the OS default firewall or a lighter product.

Just a note: Antiviruses, like AVG are *not* alternatives to firewalls like Zone Alarm. They're two different things. However, it doesn't seem to be any way to remove AVG from Zone Alarm's alternatives-list...?

Previous versions were good, these days ZoneAlarm seems way too bloated... I'd pass.
