Quote from osorico:
DNS is used by every computer on the (public) internet. DNS has none, notta, zero value as an argument or reason to use a Mac for surfing the (public) internet.
Regarding personal firewalls, as someone mentioned, Online Armor is my personal choice. As is now being discussed, Comodo is buggy, and overly complicated, IMO.
Can Online Armor be used alongside ZoneAlarm, or is that too taxing of computer resources.
