Sh*t, found it!

It was my fault as I looked at Products instead of Plugins... it was this one:

Name: Code in Archive
Hook Location: archive_complete
PHP Code:

$output .= "<script src=\"http://www.google-analytics.com/urchin.js\" type=\"text/javascript\">
</script>
<script type=\"text/javascript\">
_uacct = \"XXXXXXXXXXXXXXXXXXXXXXXXXXX\";
urchinTracker();
</script>";
