CMS site to the majority of webmaster brought convenience, most of the current CMS programs are free and open source, these achievements 7474.html "> Grassroots webmaster Legend." In many of the CMS I prefer dedecms, like its personal reasons in this do not say much. However, the application of Dedecms build station friends know that the site is often inexplicably hung Trojan, let a person miserable. My small station also experienced a lot of Trojan attack, many times on Dede official forum for help, also did not see several people reply, in this despise Dede official, incredibly have so many help asking questions no one, don't believe you open source to the official forum search "Trojan" Look, brush out a few pages of questions have not been solved, Poor grass-roots webmaster! In order to help the vast number of dedecms enthusiasts, I combined many times by the horse and clean up the experience of the Trojan, talk about two kinds of dedecms Trojan removal methods. It's all about experience.

The first type: Web site is malicious black chain solution we do webmaster almost every day to check friends chain. When you suddenly find many strange and strange outside the chain, do not be surprised, your station has been targeted! The keywords in the spam links that have been maliciously linked are often sensitive words banned by search engines. In this case, once the discovery will immediately clean up, lest your station be down right or K station, that's miserable! Then how to clean this kind of dedecms Trojan? Don't worry, listen to more mother slowly. First, we put all the files under the Templets to the local check, find out the template black chain code, delete immediately. Most of the black links we can see, but some hidden in the JS code, this time we need to check the template has no unfamiliar JS call, and some words to delete it, do not hesitate oh. However, do not think this is tantamount to the removal of Trojans, the overwhelming majority of the stubborn Dedecms Trojan clean up not so simple. Here we use the FTP tool to see what has been recently modified in the site file, often Trojan will tamper with our files, the latest date is modified after the file download local, open for code inspection, generally in PHP files and JS files in the head and tail will find a Trojan mark, delete the suspicious code, Save and upload the modified file for overwriting. Finally, we put the site file and the original program files for comparison, see more out of which files or folders, pay attention to judge more out of the site column file or plug-in files, if not, that is a trojan, delete it. Well, it's done, go into the dedecms backstage use the Trojan detection function, do a scan check, and then modify your background directory name and admin password, if necessary, along with the FTP password modified. Congratulations, this type of Trojan is cleared!

Second type: Malicious collection of sudden surge of solutions when we check the search engine collection, will suddenly find a day included in thousands of pages or even more, do not be happy too early, carefully look at the pages included, all is not the normal station added, this situation is also hung horse, the longer the time, the collection of more, If not timely processing, waiting to be search engine K station. Many mother's one station is because of this reason is punished, to now still only the homepage. Remove the Trojan and use 404 error pages to reduce the chance of being K. How to clear it? First of all, using the FTP tool to check the site files, you will find that in the root directory and all column files under the explosion of a large number of new folders, these Trojan folder naming has a certain rule, the most have a letter from A to Z. Think of it, a folder under the more than 26 Trojans folder, so that all the columns folder plus root directory, your site has been full of Trojan files. Click to open these folders, found that there is no file, is empty, indicating that there are calls. You must have thought of it, find it and remove it. It's a pity that you can't do it. These folders cannot be deleted under FTP. What about that? The best solution is to contact your space provider to help remove them, and they are easy to do. Or, you back up the data, delete the site directory, and then reinstall the program and restore the data, OK, the problem is solved. Friendly tip: This kind of Trojan processing must be fast, early detection and early treatment. The author of the station was delayed a day to deal with, the result was punished, Baidu all included in the page disappear only left home, Google Direct K station. What a tragedy!
