title: Unsure if website has been hacked with iframe
body: <p>My website seems to be loading code which doesn't actually exist on my server. I know the problem is server-side because I've tested with other computers...</p>
  
  <p>The code seems to load a header and then put's my real website inside an iframe, strangely there are no ads or redirects which I would have expected from a hack.</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"&gt;
  &lt;meta name="description" content="our real website"&gt;
  &lt;meta name="keywords" content="our real website"&gt;
  &lt;title&gt;our real website&lt;/title&gt;
  &lt;/head&gt;
  &lt;body style="border:0;font-family:inherit;font-size:100%;font-style:inherit;font-weight:inherit;margin:0;outline:0;padding:0;vertical-align:baseline;"&gt;
  &lt;iframe src="http://our real website.com/beta" style="width:100%; height:100%; border:none !important; margin:0px !important; padding:0px !important;"/&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>This is what chrome and firefox's "show source" gives me.</p>
  
  <p>I have made sure the files on the server don't contain any mention of iframes. I have also tested by creating a new empty sub directory with a blank index file but when I open it up in a browser I get the same iframe stuff! This makes me strongly suspect my server is hacked.</p>
  
  <p>What can I do in this situation?</p>
  
  <p>Thanks</p>
