Get Norton AntiVirus 2012 Free 6 months Subscription. Norton AntiVirus 2012 contains some changes to the 2011 interface, although the design is heavily reminiscent of the previous version. It keeps the dark theme, punctuated by yellow text, and the contrast works well. Changes this year include a reorganized and streamlined Settings interface; a “pinnable” Advanced screen–so that power users can get about their business faster–which also comes with a CPU gauge; and tweaks to the System Status indicator. This year, the interface feels more balanced between the feature display and empty space.
