Two idead. Dump Norton and try ZoneAlarm and Free AVG. Better, same?

On the internet, many will use just Internet Explorer and catch all sorts of SPYWARE. Since these are not a virus and Norton is just getting into the game, you have to defend yourself. Try the usual adaware, spybot to eject the common pests and then use Firefox for most browsing, falling back to IE for the occasional site that doesn't work. Better or same?
