Yes just go into:
the folder wp-content
then into the folder themes
then into the theme you are using likley to be "default"
then open the file named "footer.php"
then search for that bit of text and delete the following:
<br /><a href="<?php bloginfo('rss2_url'); ?>">Entries (RSS)</a>
and <a href="<?php bloginfo('comments_rss2_url'); ?>">Comments (RSS)</a>.
Do this with your fave text editor (e.g notepad/dreamweaver) or you can do it from the admin panel in WordPress by:
Clicking the presentation tab, then click the "Theme Editor" tab, then click Footer on the right, then delte the code as posted above.
