You need to read properly, I DID NOT say Nod32 was new, I used it years ago before most even heard of it.
ESET Smart Security IS new.
And Norton 2007 and 360 are both very good, your judging it on past resource hog builds, bit like peeps who say AMD run hot (back when Thunderbirds it was true).
You need get unstuck from the past m8.
I spend a great deal of time testing all the Betas (sign up) and decided now I will use the ESET Smart Security, but if I could disable some of the PC Tune Up features of Norton 360 I would use it instead and do for my customers.
