New computer user/security ignorant

[walterdaysi]

I just purchased a new HP dv6 notebook computer. It came with windows7,, I was offered a free Norton for 60 day's.If windows Defender is already part of windows7, Is it really necessary to have Norton?, Or is windows Defender suffiecient alone by itself.---- Is windows Defender one of the better security programs available?
