Have for several years used Norton. I have the Internet Security from the computer and first installed a 30-day trial of Norton Security 2015. The installation went quickly and smoothly. As the program runs eiwandfrei and the computer does not slow down, even when no startup and shutdown, I bought the product key and get 366 days. My system Core i7 3.6 GH, 8GB of memory and W7 OS. So it runs as it should be, so I can recommend it.
