That day my computer suddenly can not open the machine, I do not know why, then I quickly make friends to fix my computer, because there are a lot of the information I need, if I lost it, then I can go to my friends, later repaired, he told I said this is my computer there are some Targeted Attacks virus, Targeted Attacks said these things if not timely treatment, there will be such a situation, he suggested that I say is to learn more about Targeted Attacks, Targeted Attacks after the encounter this problem, also know how to solve have heard friends say this, I also understand the reason, I think is the use of spare time to learn more about Targeted Attacks, so they can better.
