The latest official major version of Norton 360 is version 2014. This was a change from previous versioning way which went from 1.0 to 6.0. In 2012, there were two versions of Norton 360 released roughly about six months apart, which made it catch up in versioning with other Norton security products: Norton Internet Security and Norton AntiVirus. This time though, Symantec advertised all three products as Version-Less, so no official version number is visible anywhere at Norton.com website. All three products are still referred to as 2014 based on their previous version history.
