Updates of virus signatures and also the program code done completely "invisible" and impalpable in the background. Computer restart needed (1-2 times per year) are very rare when an update was installed.
Directly after installing NIS 2012 computers without additional configuration, covered. Whoever trusts and wants, but the program can be very easily adapted to his needs.
The load on the system is always in the acceptable range and is not felt most of the time. Labor-intensive tasks, such as fast system scans are performed if possible, when the computer is idle times. When copying files, the delay may be measurable, but noticeable in any case. Games will not be affected and possibly aufploppende messages that could interrupt a game can be suppressed by turning on the so-called game mode.
Although NIS 2012 in some tests of computer magazines or websites only to place 3 or 4 lands (in other tests it is No. 1 or 2), so I was very pleased in recent years with the Norton Internet Security. and even the 2012 version for several months I use already (because once a new version is available, you can download it free and install) and am very satisfied.
