The following description refers to the use of a Windows PC (here: Windows 8.1). For my Android smartphone I can currently do without even a clear conscience to a virus protection, and Apple hardware I do not possess.
After calling up the setup website in Norton you are there the license key and registers itself with giving e-mail address and password. For more information, you do not have deposit at this point. First you load a 1 MB download manager down, which in turn the installation packages of 120 MB size in a directory on the system partition downloads (C: \ Users \ Public \ Downloads \ Norton \ {...}).
Installation and Setup run smoothly and also for inexperienced users from without hurdles. After the installation there in the taskbar, a new icon that you can call the Norton Security Administration. The interface is attractively designed and clear. In addition to the pure virus and malware protection some nice hygiene activities are carried out, such as removal of tracking cookies, cleanup temporary files or media optimization (using Windows functions). In addition, one finds superfluous as an online password generator - use is a not forced upon.
On the Norton website you can maintain your own user data such as email address, name, or password, and also display the licensed (in this version) up to five devices and manage or remove from the subscription.
In runtime behavior the Norton Security is unobtrusive. The system will in any case not noticeably slowed down, either at startup, even during shutdown or at the start of complex applications (have the rough times mitgestoppt).
I would want a clearer distinction between protection functions and "schmückendem" accessory whose essential purpose is probably the user to give me a pleasant feeling of cleanliness.
But real problems or deficiencies I could not discover. As for the level of security, you have to leave so independent experts in the tests (hopefully). Here the Norton suite cuts anyway from respectable.
