Well norton 2006 products were released today.
The dark side of the force :-*
Pain and suffering 
I wonder if it will be faster than previous versions. Also i found a way that you can update norton free after your subscription to live update expires there is a part of there site where you can just download the update and install it manually. I guess live update is only to download and install it for you. Not like it matters
I will never have to worry about how fast any version of NAV is as it will never see the light of day on any system of mine. It has form/history as being a resource hog, conflicts and worst of all a real pig to get rid of.
