Adobe Analytic JS tags generated in IE 10

The following two tags:

<script type="text/javascript" async="async" src="........._setAudienceManagerFields”>

<script type="text/javascript" async="async" src="...........setAnalyticsFields">.

are being automatically generated in IE. Their placement in the code is causing some layout issues within the webpage.

What is the purpose of these scripts and why are they being inserted in IE browsers?
