I visited a site not on the 'safe' list of my browser and got hit with this crap. There are online aids and how-to's for cleaning this off your machine. I was running AVG and Threatfire at the time and it still loaded and executed. I believe the package was delivered in a flash movie but could have come from the web page that embeded the flash. Either way I was lucky I had other boxes to search the net for solutions.

IMAO, I think when these people are found they should be summarily executed - but slowly. Their screams of agony would be music to the ears of millions of victims around the world.
