logo icon on top adress line

Hi forum, to understand my question, please use CHROME as browser. In opening www.fleifood.de I see an icon of the letter "m" in the top page line of the browser that says "fleifood.de - Erste online.....". This "m" is the logo/icon of the www.modified-shop.org , which I run for a different site but never hat the shop installed on fleifood.de. I want to get rid or change this icon. Where could I do this. Regards Helmer

I don't see that?
