This development was long overdue, since the versions 2012, 2013 and 2014 differed only marginally and the software lives from being updated and not by annual upgrades. Moreover, different versions for PC, Mac or smartphone are no longer appropriate.
Who still uses a "predecessor program" can continue using it and is supplied with updates or change.
But that does not work - as before - automatically, but only by reinstalling the Norton Securities. The old activation code then however no longer work and you need to contact support, which enabled the new installation in accordance with the remaining maturity.
If the "switch" (probably better upgrade) necessary?
In the short term does not, in the medium to long term certainly
Who with his current program package so far is satisfactory, should mE wait some time until the first teething troubles are resolved. A look at the relevant forums can help to find the right moment.
Then he gets a good security software that is economical with the PC resources, that the PC slows not noticeable, is updated quickly and provides a good compromise between safety and comfort.
In addition, there are now affordable Paketlizensen for up to 10 installations and a backup version that allows to back up to 25GB in the Norton cloud, which I can do without, because there are good and free alternatives and a backup in the cloud for do not come for reasons of speed and data security in question.
