Have so far as security for my previous laptops freeware used. Basically better than not to protect. But through my job I get every day with what attacks you are exposed to these days on the net. Besides, I was not necessarily satisfied by the performance of the previous freeware and also the computer. With my new device I received a 60-day trial version of Norton Security. I was thrilled - everything is monitored and in real time. For every download and every .exe gives instant feedback. The program runs eiwandfrei and especially without any noticeable effect on the speed of the computer - even at startup and shutdown. Therefore, I have now decided to go for the paid version. I feel safe now. The installation with the product key runs quickly and smoothly. I will also stay with weitrhin Norton - better safe than sorry.
