_header.html is giving tough time

Hello,
I have placed the following codes at the end of _header.html file, which is present in tmpl_uni folder.

<div align=center>
<!--/* Profuse Host Javascript Tag v2.4.8 */-->
<script type='text/javascript'><!--//<![CDATA[
var m3_u = (location.protocol=='https:'?'https://ads2.psychz.net/www/delivery/proajs.php':'http://ads2.psychz.net/www/delivery/proajs.php');
var m3_r = Math.floor(Math.random()*99999999999);
if (!document.MAX_used) document.MAX_used = ',';
document.write ("<scr"+"ipt type='text/javascript' src='"+m3_u);
document.write ("?zoneid=8");
document.write ('&amp;cb=' + m3_r);
if (document.MAX_used != ',') document.write ("&amp;exclude=" + document.MAX_used);
document.write ("&amp;loc=" + escape(window.location));
if (document.referrer) document.write ("&amp;referer=" + escape(document.referrer));
if (document.context) document.write ("&context=" + escape(document.context));
if (document.mmm_fo) document.write ("&amp;mmm_fo=1");
document.write ("'><\/scr"+"ipt>");
//]]>--></script><noscript><a href='http://ads2.psychz.net/www/delivery/prock.php?n=a282ba6a&amp;cb=INSERT_RANDOM_NUMBER_H ERE' target='_blank'><img src='http://ads2.psychz.net/www/delivery/proavw.php?zoneid=8&amp;cb=INSERT_RANDOM_NUMBER_HE RE&amp;n=a282ba6a' border='0' alt='' /></a></noscript>
