The advertisment is written in german language and tells you, that you have won 500 Euro or a Galaxy7 and you have to push the ok button to get it. If you push the close button you will redirected to a website with simple questions.

It seems that this PopUp is a stowaway of the normal advertisement which you show on your main site.
Can you stop this typ of advertising. It makes your site not longer usable.
