In 2011 I had ordered me for the first time, the Norton Internet Security, because I wanted to see if I was still something better than Kaspersky get, the price was certainly favorable. Since I was very happy I ordered an upgrade in 2012. I have Windows XP, have inserted the CD and am proceed to description. The old version was initially deinstalliert.War bit confused when I was asked if I want to uninstall the 2012 version. Have this year taken the opportunity to install the free version already in 2012. After uninstalling and Neuinstallatin everything worked flawlessly and the settings of the previous version were also the same as taken. Of course, saving time and effort, because you have nothing to configure after installation. The installation itself went on my PC quickly and without any problems. The menu of the 2012 version is quite clear that German. Should you have any questions or problems autreten, so you can by clicking on the option "help" find the same solution online, I can only recommend.
As with previous versions, you have the feeling as if hardly any security suite, so discreetly done the program its tasks in the background. Scans and tasks are performed as usual only at idle, under settings "Computer Scan" you can set whether and when to scan, and do not prevent therefore. Also when you boot the PC and surfing the internet, I can not detect any delays by NIS in 2012. However, my PC runs anyway not as fast as initially.
All in all, I recommend Norton Internet Security 2012 only fully. Top product!
