Personally, I wouldn't touch ZoneAlarm with a 5-foot pole. This is what I would recommend (as I've used these on my old computer: Firewall: TINY Personal Firewall, KERIO Personal Firewall, BitDefender (has virusscanner included) Virusscanner: AntiVir, BitDefender, AVG Antivirus Well, BitDefender isn't exactly free, but it's extremely good. Better than Norton IMO.
