Most of the sites are hanging horse is the site program defects caused by the server on any one of the Web site program problems can cause all the sites on the server are attacked. Not only that, from the search engine rankings, if a server on any site by K, then the server on all sites will be implicated ...

In the purchase of space to choose the more well-known authority of the service provider is more secure, do not cheap. Website flaw, the security of backstage account password is important. If the webmaster does not have security awareness or covet short easy to remember, the account password set is too simple, for example, some CMS system default account and password is 123456, such as the password even I such a rookie can crack, not to mention the specialized destruction of the experts. In addition to the background account password there is an important factor: Web site program vulnerabilities. In recent years, a variety of powerful web site management systems emerge, such as Dedecms, the Imperial CMS, greatly saving the time and cost of the site, resulting in a large number of Web sites flooded with this website management system to make.

Exclusion: If you can't tell the Trojan file, you can also use the most stupid method to eliminate the law. I have said above, Trojan files will generally be placed in the directory relatively shallow path, find it relatively easy. The carpet-seeking method works well for beginners. Specific approach: from the site root directory in turn with Notepad open rom extension asp.php.html and TXT file, the text appears in the "Hanging Horse", "Detection", "command" and other words can be immediately judged as a Trojan file. As shown in

Before the complaint, to confirm the Baidu snapshot of the source code contains the black chain. In general, Baidu's search box to enter their own web site, in search results can be seen. Confirm the search results in the first page of the description of the presence of black chain information, if not, click on Baidu Snapshots and open source code to see if the information contains black chain (above the black chain is just an example, some black chain will appear in other forms). If the black chain exists, you can complain about Baidu snapshots, generally in 24 hours will have results. After a successful complaint, the ranking can be restored.
