We have Norton 360 are 5 years in use and are very zufrieden.Bisher no viruses or similar who can cause damage. The remaining time of the previous subscription, we probably acquired when it extended beyond the account! Whether one (clean up, optimize ...) the additional tools needed, everyone must decide for themselves. But they are useful and easy to use for each untrained already. Disk optimization not forget to switch off only when SSD disks !!! The upgrade version extends the way to extend an existing 360 Subscription!
