Thank you, Lucky. Yes, i think it was a security problem in an older version of WordPress. I replace all files and update it. I think i must to wait some days to Google update my index description. But i would like to learn how to manage it, it′s Yoast SEO plugin or something like that? Thank you.

Nobody knows this particular attack? Because it was changed again
