The Kelihos botnet only infected 45,000 or so computers but managed to send out nearly 4 billion spam messages a day, promoting, among other things, pornography, illegal pharmaceuticals and stock scams. But it was temporarily corralled last September after researchers used various technical means to get the 45,000 or so infected computers to communicate with a "sinkhole," or a computer they controlled."
