I rekon Mcafee is better, Here in NZ we can get it from our service provider & it updates daily. this 1 is a cost of approx $15 per month in the phone bill

Nortons only lasts for 1yr n then you have to spend more money to get an updated disk at a cost of around $70NZD.

I myself prefer Mcafee, but it's up to the individual which programme they choose.
