threat defense

My computer is usually also occasionally some problems, like others how computer is not what problem, but I also really did not think this is the original I also used the threat or defense, is one of my friends told me, she said recently, there have always been in a very good threat defense, so usually is to use the threat defense that it really is not what the computer outlet problem, but also there is a problem still can come and timely solve, so I am very happy too or use the threat defense, the threat defense is feeling very good very good, especially good.
