Strange code has appeared on 2 of my pages, what is it & how can I remove it?

[ALS1]

This code:

(function(d,s,id){var z=d.createElement(s);z.type="text/javascript";z.id=id;z.async=true;z.src="//static.zotabox.com/d/e/de0654cdcc5194e0f018d7ba4c23c37a/widgets.js";var sz=d.getElementsByTagName(s)[0];sz.parentNode.insertBefore(z,sz)}(document,"script","zb-embed-code"));

Has appeared on the very top of 2 of my pages:

https://www.dazzlevintagefurniture.com/antique-mirrors.html

and:

https://www.dazzlevintagefurniture.com/french-armoires.html

Please can someone tell me how to remove it?

@ALS:  looks like it has something to do with zotabox widget

I think you're right, BobaFett. I can't seem to find the element on the homepage in the editor. Do you remember installing this app, @ALS?

I haven't installed any apps. This code has only appeared in the last couple of days, it was most definately not there last week. Any ideas as to how I can remove it? I've checked the settings/SEO and there is nothing in the headers. Help!!

Further to my last message I've just been to the apps in settings and there was a social sharing thing that I tried out once and didn't like so I removed it from the site. Having just deleted that app completely the code has now gone! Very strange. Thank you for your replies.
