Symantec will consolidate its cluttered Norton line of security software, folding nine products into one online service that can be used across desktop computers and mobile devices. The product, in beta now, will simply be called "Norton Security" and cost $79 a year when it goes on sale in North America on Sept. 23, said Gerry Egan, senior director of product management. It replaces Norton Internet Security, Norton AntiVirus and Norton360, among others.
