2 years ago I loaded Norton 360 Ver 2 from a disk. Earlier this year I got a free down load to Ver 3. I now wish to load the Ver 3 to a new computer and do not know how to go about this. Do I load the programme from the existing Ver 2 disk and hope that it will be upgraded or can I download it direct from Norton. There is a 3 computer use with the programme which expires in July 2010.
