ZoneAlarm is one of those firewall's that every tech magazine recommends but is never really talked about in detail on this site. I have not used this firewall in a year but now that I am in the hunt for a simple to use firewall I have been looking into ZA again. Last version I used was v8....... Is version 9 lighter then version 8? How well is ZA at protecting a machine? Does it come with a white list of known good apps? Any known issue with Panda Cloud?
