Hide Plugin Details from Page Source

Hi there,

I have recently installed WP 2.7 and have added some plugins. In an effort to strengthen the security of my blog, I would like toknow if there is a way for me to hide plugin details from being shown in the page source.

Here’s an excerpt:

<!– Start Of Script Generated By WP-DownloadManager 1.40 –>
<link rel=’stylesheet’ href=’https://www.XXXXX.com/wp-content/plugins/wp-downloadmanager/download-css.css?ver=1.40&#8242; type=’text/css’ media=’all’ />

<!– End Of Script Generated By WP-DownloadManager 1.40 –>

<!– Start Of Script Generated By WP-EMail 2.40 –>
<script type=”text/javascript”>
/* <![CDATA[ */
var email_ajax_url = ‘https://www.XXXXX.com/wp-content/plugins/wp-email/wp-email.php&#8217;;
var email_max_allowed = ‘5’;

thaks for looking.
