I'm not sure about the new build of (free) ZoneAlarm - it seems a bit "clunky", somehow. The window looms just a little too largely on my screen - it used to be quite dinky, just the way I like my PC tools. Now its a bit of a "brash" bully-boy. And it annoyed me upon install when it tried to pimp its high-class hooker of a firewall, Zonalarm Pro. What do they expect - punters to actually pay for their top-class firewall? Oh yes, I see. Fair enough.
Anyway, there may be some important things going on under the bonnet, but its the presentation that counts.
But I would say that, 'cos I'm thick and beautiful.
