The only people who think Norton is a good idea are adults who don't understand computers very well and children that are forced to use it.
Same deal with McAffe. I hate them both equally.
Avast! is my choice, also Malwarebytes. I haven't seen or used AVG or MSE so I can't say much about those.
edit:
To those who say people who use antivirus at all are dumb, that's the equivalent of saying wearing shoes and socks is dumb because it'll be your fault if you go somewhere that will obviously threaten your bare feet.
Or that it's a dumb idea to wear a jacket in cold weather because it's your fault if you don't get to a warm place and experience hypothermia.
Or that it's silly to wear a gas mask into a building on fire as a fireman because it's your fault if you breathe at the wrong time.
Obviously, if you walk straight into the fire, though, that's your fault and you're a dummy.
