I'm not exactly sure what I am supposed to check, so I took a screen shot. I hope this helps. I hope you can figure out what the issue is, because it is causing a redirect in the search engines. Let me know if you need anything else and I will get it to you ASAP.
Just looking at it. And i havent got the faintest idea where that one is coming from. Even with all plugins off it shows and replaces the favicon aswell.
i have to ask some of my colleagues to take a look as well. leave the login details intact please.
