I do not know how people understand this sentence, I put my understanding to everyone to listen to, since the site was hijacked by DNS, causing the existence of Trojan holes, then if the user on the site to conduct transactions there is a great risk, such as Baidu will give you the site rankings? The answer is conceivable, Baidu This simple sentence is a short fall right, and so you deal with the relevant loopholes, in come to me to claim recovery bar.

All right! We still have to address the vulnerabilities of the site, in this I will be how I deal with the site vulnerabilities to tell you.
