Zone Alarm - conflicting messages
I need guidance on conflicting Zone Alarm messages. My question is: do I or don't I have a working Zone Alarm firewall?
When I mouse over the ZA icon in the Start Panel, it says "ZoneAlarm Your computer is protected". The version is 11.0.000.018. When I manually try to update it, it reports that it is updated.
However, I happened to open FF 20.0.1/Tools/Add-Ons/Extensions and noticed that ZA is greyed out and it says "ZA Security Engine is incompatible with FF 20.0.1". The Security Engine is 1.5.393.18 (disabled).
Meanwhile, I've re-enabled the Windows firewall as a precaution.
If the ZA is non-working, I'd appreciate suggestions on a compatible free replacement.
COMPUTER: Win XP with SP3, wired WPA router, MSE, MAM, SAS, Spyware Blaster, Spybot S&D, All software basically updated.
