title: Unknown scripts are prepending before html body close tag
body: <p>From today morning, i found some unknown scripts are prepending just before the       "body" close tag, The scripts are :</p>
  
  <pre><code>&lt;script&gt; var addthis_config = {"pubid":"ra-554ac5c71847b3c2"}; &lt;/script&gt;&lt;script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid=ra-554ac5c71847b3c2"&gt;&lt;/script&gt;
  &lt;script&gt; if (addthis &amp;&amp; addthis.layers) { addthis.layers({'share':{'mobile':false}});}&lt;/script&gt;
  </code></pre>
  
  <p>I had not added this piece of code to the website. I was searching for the root cause for this. But until this moment i cannot find a solution to remove this script. What i did/observed so far :</p>
  
  <p><strong>Removed "body" close tag :</strong> No script</p>
  
  <p><strong>Tried to add an html file(with basic tags) index.html file :</strong> found the script is injected right before the body close.</p>
  
  <p><strong>Scripts are only seen at the home page.</strong></p>
  
  <p><strong>The files uploaded to different hosting with a different domain :</strong> No scripts</p>
  
  <p>The web server is Apache, and the content of .htaccess is as shown below:</p>
  
  <pre><code>&lt;IfModule mod_rewrite.c&gt;
  &lt;IfModule mod_negotiation.c&gt;
      Options -MultiViews
  &lt;/IfModule&gt;
  
  RewriteEngine On
  
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^(.*)mywebsite\.ae [NC]
  RewriteRule ^(.*)$ http://www.mywebsite.org/$1 [R,L]
  
  RewriteRule ^(.*)/$ /$1 [L,R=301]
  
  # Handle Front Controller...
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^ index.php [L]
  </code></pre>

  <p>The website is hosted with Amazon Web services. Does anyone have such an experience before ?</p>
