mysterious anchor text in header

I have purchased support for the problem I am having and hope I can get some help. I'm seeing an anchor tag in my header and have no clue where its coming from. The site is nwcchiro.com. If I enter the URL without the www, then only this odd anchor text appears, nothing else. If I enter the full URL in the browser, I see the anchortag intermittently on various pages. Its not consistent. I've cleared cache and its gone for a bit then reappears.... I've looked at the header.php and other php files but find no trace of this tag. The anchor tag is always the same and has nothing to do with the site or even our geographic location. Also if I am logged into wordpress, I do not see it. I've searched for solutions but am a total loss... Here's header section with "****" next to the questionable tag: <header id="branding" role="banner"> <div id="header-content" class="clearfix"> <div class="logo-wrap clearfix"><div id="hgroup" class="site-details"> <h1 id="site-title">NWC Chiropractic</h1> <h2 id="site-description">Changing Chiropractic One Patient at a Time</h2> ****installment loans online sacramento, california </div><!-- #hgroup -->
