Malware within PageBuilder CK?

Ever since I've started using Page Builder CK a link keeps popping up in my page from "Website Builder Point" that links to www.websitebuilderpoint.net/website-builder/
Is not there all the time, it appears and disappears, but it keeps popping up.
Is there a way to get rid of that?
I've added images of the front page showing the link and of the inspector showing that it's inside the PageBuilderCK component.

Thanks in advanced

Hi
there is nothing like that in my code
I can also tell you that the code appears when the module "custom" is rendered in the page, not when Page Builder CK is loaded

there is for sure a problem, but the code is probably located in the joomla files or in a plugin triggered when a module is called
