Norton should make sure that their Antivirus, Internet Security and 360 software is 100% fully optimized for 64 bit operating systems. It means that their Security software is not a 32 bit application as the whole world is moving forward towards 64 bit desktop computing in future. You also need to make sure that you make 64 bit versions of Norton security products available for 64 bit versions of Vista SP2, 7 SP1 and 8/8.1 because by 2015, we no longer need any legacy 32 bit operating system support anymore as Windows 9 will only be a 64 bit operating system. Can you please make that happen?
