I switched this year from Norton to G Data and despite initial fears, due to some reviews, I do not regret it. The box comes with an installation guide, which will keep some unnecessary, but I did not previously know that there are removal tools of the individual companies in order to remove in this case, Norton really complete. The installation was very easy, everything went smoothly, then came the update and I let out right now by scanning everything. G Data actually took four viruses that Norton had overlooked. My fear that G Data at least my anyway would not slow down very fast laptop additionally, has not been confirmed. My laptop is now running faster than before, and on the first day, right after the first scan. I'm very satisfied! That was a really fortunate coincidence that I could not find any 2015 version of Norton on Amazon and have therefore decided to use G Data!
