Obama Trojan

Ever since the end of the election, there has been a Trojan virus that has been riding the coattails of the Obama victory speech. here is a quote from the article " Several security tool vendors -- including Cloudmark, Sophos, and Websense -- today are reporting massive amounts of spam messages that promise video clips of an "amazing" Obama speech, election news results, or interviews with Obama's advisers. These messages are carriers of malware that can compromise users' PC, researchers say. The three vendors offered differing descriptions of the attack, which suggests it may be working under different disguises. But screen shots provided by both Cloudmark and Sophos contained identical photos and text, indicating that much of the traffic is being generated by a single exploit."
