I'm looking for buying a anti-virus program and haven't decided yet which one to use. I've heard that Norton AntiVirus is ok, but I've also heard that there are betters -> I've been hearing throughout many years lots of good things about Kaspersky Anti-Virus, but lately I've heard good things also about newcomer namely NOD32. I'm targeting the usage for normal home use. I'm already using ZoneAlarm so firewall options aren't important. I'm also quite familiar and learn easily new programs so the ease of usage isn't important. Gimme your opinions! Which one should I buy?
