I don't believe your computer is infected with anything, and this is why...
This is very clearly at the very bottom of your page code:
<script type="text/javascript" src="http://b.scorecardresearch.com/beacon.js"></script><script type="text/javascript">try{COMSCORE.beacon({c1:2,c2:7518284});}catch(e){}</script><noscript><p class="robots-nocontent"><img src="http://b.scorecardresearch.com/p?cj=1c1=2&c2=7518284" alt="" style="display:none" width="1" height="1" /></p></noscript><script src="http://s.stats.wordpress.com/w.js?19" type="text/javascript"></script>

addLoadEvent(function(){linktracker_init('17744093',0);});
</script>
Wordpress does not allow users to insert javascript code into pages. The only javascript that should be in your page code should be either code that is part of Wordpress itself or code from widgets that they approve and make available to users.
In other words, unless this is some feature you selected from some menu, preapproved by Wordpress, then Wordpress had to have added it without you knowing, or Wordpress itself got hacked (not just your site) and someone has inserted it into their wordpress code that is being used on all sites they host.
