HI Chuck
All you would need to do is go to the theme editor in your dashboard and find the footer.php file. Once you find that, do a control find for the said text.
Then, either remove it, comment it out (//), or remove it all together. However, be very careful when removing it, because if you remove too much info from that, your site could crash with syntax errors.
Let me know if you need more help.
Mike
