Little line underneath footer

I've been updating plugins and the theme on stillprotectingyou.com (It's ugly, I know - not my fault) Anyway, there is this weird random little line below the footer.

Upon further inspection with Firebug, I believe it to be the below line of code causing this issue. I don't know how it got there and i'm not sure how to get rid of it.

Any suggestions, as always, are greatly appreciated! Thanks!
