Strange Code Appearing Automatically

I just updated to the latest version of wordpress, and I’m having a strange bit of code appear whenever I start a new or update and existing post/page…

<input id=”gwProxy” type=”hidden”><!–Session data–></input><input id=”jsProxy” onclick=”jsCall();” type=”hidden” />

And idea what could be causing this? Could it be coming from one of my own plugins, or is this malicious?

Thanks,
