I have no idea what secure_cart.tpl is, and don't see a reason for it to be created, what does it do?
Are you using Fast Lane Checkout? If so, try putting this in skin1/modules/Fast_Lane_Checkout/home.tpl just before the closing </body> tag....
Code:

<script language="javascript" type="text/javascript">
//<![CDATA[
var cot_loc0=(window.location.protocol == "https:")? "https://secure.comodo.net/trustlogo/javascript/cot.js" :
"http://www.trustlogo.com/trustlogo/javascript/cot.js";
document.writeln('<scr' + 'ipt language="JavaScript" src="'+cot_loc0+'" type="text\/javascript">' + '<\/scr' + 'ipt>');
//]]>
</script>
