deleted plugin; still error text appearing on webpage

I am not a very “smart” WP user (yet); but certainly learning as I go.

Last few months, I noticed at the bottom of my website pages, there is some random text appearing (but without any buttons to click). It took me awhile to figure out which widget was causing the issue, though I’m pretty certain it’s this Social Share.

I have since deactivated the widget–not resolved. I’ve now deleted the widget entirely, but there is still this text appearing at bottom of the page (next to “Subscribe” button and above the “print” button).
Here is a screenshot of how it appears:

Can someone, anyone, please help me out?! How do I get this removed?
