trojan from pingomatic

i went to check out pingomatic.com, and when i clicked on the link to their ‘stats’ page, my av program (nod32) popped up a red alert that the file ‘https://pingomatic.com/stats/’ contained the ‘Win32/Exploit.MS06-006’ trojan and prompted me to terminate it. this happened in both ie6 and firefox 1.5.

i looked around the pingomatic site, but could find no link there to contact anybody about this; i also searched these forums for references to it and found none. i thought that, since wordpress uses pingomatic as their default update sevice, someone here must know someone there, and regular wordpress users should know about this.
