Botnet Statistics [2009-12-16]

Bots from countries other than Taiwan started to show up in the new detection system, though the overwhelming majority (more than 99%) were still from Taiwan. Today's statistics is calculated in the same way as yesterday. I take most of the numbers from the old detection system. Only Taiwan's numbers (as there are many networks in Taiwan) of bots are taken from the new system.
