This article mentions the work group that created the chart http://news.cnet.com/8301-1009_3-10210934-83.html And as my understanding is this virus will block access to anti-virus websites so the top row of icons would by that theory not work properly in image or link if you're infected. If you can see the icons and click on them you should be safe.
