Unexpected code at the end of portfolio pages

Hello,
some of my users told me that opening some portfolio pages on my site, antivirus software tells S ScriptIP Trj is present.
I found in the source page of the portfolio pages this code:

<!-- this is used by many WordPress features and for plugins to work proporly -->

	<script type="text/javascript"> Cufon.now(); </script>

	<script type="text/javascript">

	<a href="http://www.framedreality.com/download-filezilla.html">Download FileZilla manager</a>

	<a href="http://www.destitutegourmet.com/download-filezilla.html">Free FTP-manager FileZilla </a>

	<a href="http://www.stephanelambert.com/download-filezilla.html">FileZilla for operating system Windows</a> </script>

Is there something wrong with those links?
Thank you
