I also use ZoneAlarm Pro and love it. I USED to be a big fan of Symantec and their various Norton products (always upgraded to the latest versions when they came out), but, to combat piracy, they have taken some pretty irritating anti-piracy measures that MAY be at the root of many of the problems people have been experiencing (at least, the problems have been coincident with the anti-piracy measures, if not actually caused by them). Symantec has taken a "who cares" stance and not done much to address the issues. So, I, for one, have decided to say "who cares right back atcha" and have stopped buying Symantec. Do yourself a favor and avoid Symantec like the plague.
