Footer help

Hello, in a previous version of wordpress and responsive theme, I got involved with footer and changed some things. With the newer version of responsive theme, I noticed that I can channge the footer without css code, through Apearance->customize->footer widget.
Anyway I now want to get rid of the previous footer I created but I can’t find it in the editor menu. Here is the image, https://www.dropbox.com/s/lkpwvmz7tkhociz/pic.jpg

I want the red mark to disapear. I use the firebug and shows me the following code:

<div id="footer-wrapper">
<div class="grid col-940">
<div class="grid col-300 copyright">
