Out of all the firewalls I've tried, I found ZoneAlarm to be the most user-friendly for my needs.
But there are a couple of issues that test my sanity around ZA.
I'm running XP Home SP3 and ZA Security Suite v8.0.298.000.
Example 1: about 6 months ago I uninstalled Avast AV and Avira AV from my system. Did a thorough clean and swept the registry for remnants which I deleted. Tonight several of those AV system files reappeared in ZA's Program Control list of programs. This kind of thing has happened many times over the years of using ZA. I've reinstalled ZA a number of times but these ghost files reappear out of the blue, maybe after a system reboot or simply just randomly.
Example 2: I spent frigging hours trying to find out why Firefox won't play YouTube and other movies. One of my fave sites is Ted.com with its video lectures which does not even open properly in Firefox. Researched it wherever I could. Tonight on impulse I turned off ZA and voila! The Ted site works beautifully.
All along I suspected Firefox when in fact the culprit seems to be ZA!
Has anyone here had similar problems and how did you fix them.
Thanks with gratitude!
