This article on fake google and some Panda Software finding that out makes me wonder if this is all the creation of Panda Software (where in hell did they come from), to come into the limelight. Note the line about Microsoft, Yahoo and Google refusing to comment.
Infact sometimes, I wonder, why shouldn't Anti-virus companies have a Virus Division which lets loose the most dangerous of viruses. Then they'll have a head start over the other anti-virus companies in finding a anti-virus patch upgrade for it. Maybe they already do.
