threat defense

I and my bestie machines are bought together, but I made some time ago can not make good use of the results, I bestie machine with time just to buy the same good, I feel very unexpected is not good, then I realized that it was my bestie installed this threat defense for their own machine, I do not believe it is because of this threat defense to install the machine has been so good, then try holding the mentality before deciding to install this threat defense, but the fact is that I have to believe that, after the installation of the threat defense I found the machine a good, since those all refuse to eliminate out of order.
