Now I regret not what ah, I can only is the use of spare time, the knowledge of this threat. Learn about the, otherwise, the next time meet this threat. I still don’t know how to solve. A few days ago, inside our company are saying this threat. And later we also really is used some threat defense knowledge, other colleagues soon put to resolve the matter, but I don’t know how to do, later can be only let others help me finish, from then on. I think it the threat defense knowledge really is very important, so I think I really should learn about the, so it is good for me.
