First, before I installed the software, I was negatively surprised by the enormous waste of packaging. Here one gets a large ca. DinA 5 approx 1cm thick cardboard box, from which you then simply need to take out a small piece of cardboard the size of a bank card itself. Then find the serial number on the back of this card. This one has to yet to scratch off, and then follow the easy steps on the map. After entering the URL shown on the card you have to enter the serial number there and then comes to a another page. There you have to then register short (but only if you like I was as yet no Norton customer). After registering the download of Norton security software starts automatically. , The download time is manageable. After downloading the software automatically starts then also with the installation on the device. After installation, including extensions completed for the browser and the computer were then restarted Norton displayed an an initial screen. It will quickly and easily explains the options and menu items of the program. All in a very pleasant and comprehensible way. If you have then logged with its data, the menu interface remains the same as it was seen at the small launch. I feel is pleasant. Everything is straightforward and easy to use. A software update has the software then automatically checked immediately. By simply clicking on the corresponding menu item, but one can at any time be manually search for it. Scanning the device can be normal (in this case be the main areas of the computer controlled) or let make completely. The pace at the normal check is very fast in my opinion. But the intensive scan works quickly and reduces the performance of the computer during this time is not really noticeable. In the browser extension appears first on a window with the Norton the user then wants to get you to use the search engine Ask an apparent advertising partner. This but you just can negate a click and then is no longer such a display. And so the program runs quietly and unobtrusively in the background, does not slow the computer and has not protected me very effective against viruses, trojans or Fishing mails etc.. Since I use Norton for the first time, I can not draw any comparison to previous versions. But in the Norton Security software you have the manufacturer Symantec really combines all components for a perfect all-round protection of the devices.
