hidden code / text in wordpress footer

i had an issue with a ‘hidden’ text under the main footer…

there was a link to “PHPlist” site under the footage, but i couldnt find any place where to edit it out…

under appearance editor, the footer.php contained a code and i removed it:
<?php wp_footer();?>

but… wp default footer code is <?php get_footer();?> ??

any ideas where does the “wp_footer” code fetches it’s data? didnt find any text containig “phplist” in functions.php etc (under wp-includes)… (checked couple of them)
