Computer recently do not know how old, is a problem, but it also knows a friend gave me a threat defense installation, and to me that this threat defense is especially good, so let me have good with it, did not think after installation this threat defense my computer is a lot better, and is especially good for, I also really is very happy, this time I must thank the good friends, because it is ever since the threat defense my computer is especially low there what are the problems of it, I’m really very grateful to him, have never thought of such a good use.
