Suspected Error div on web pages of YontooInstallID, Y2PluginIds

Question

I have found out that, while Inspect Element on chrome or firebug on mozilla, i found these strange invisble divs..

how can we remove this.. or is some kind of intrusion...

below is the code

<div id="YontooInstallID" style="display: none; ">7811f3e7-3895-42ae-901d-1fd7f3092229</div>
