I am using Windows 7 Home Premium (64 Bit) and NIS 2010. I recently had an opportunity to check out Norton 360. I like some of the features of Norton 360 (registry clean up, backup, etc.) I think your PC Checkup does the registry cleanup, backup, etc., but I do not wish to subscribe to it. My subscription to NIS 2010 expires in January, 2011. Can I opt to upgrade to 360 at that time? Does both NIS 2010 and Norton 360 provide same internet security, spyware, etc.? Which product is better?
