Script still there after removed plugin

Hi,

I had a “facebook like” plugin and now I removed it. However I still have this script after the footer tag. I want to remove it manually, but I don’t know where to find it.

<!--facebook like and share js -->
        <div id="fb-root"></div>
		<script>(function(d, s, id) {
			var js, fjs = d.getElementsByTagName(s)[0];
		  	if (d.getElementById(id)) return;
		  	js = d.createElement(s); js.id = id;
		  	js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.5";
		  	fjs.parentNode.insertBefore(js, fjs);
		}(document, 'script', 'facebook-jssdk'));</script>
