How to remove strange div called dp_swf_engine from html page?

Question

On my site, I recently found a strange new automatically generated div. when I look at it in development tools in chrome I says:

<div id="dp_swf_engine" style="position: absolute; width: 1px; height: 1px;"><embed style="width: 1px; height: 1px;" type="application/x-shockwave-flash" src="http://www.ajaxcdn.org/swf.swf" width="1" height="1" id="_dp_swf_engine" name="_dp_swf_engine" bgcolor="#336699" quality="high" allowscriptaccess="always"></div>

I really don't know what it is, and where it's coming from.

I already had a similar problem and the div came from a chrome extension, check which extension can modify your pages.
