Taiwan, where I live, had stayed on my list of top 10 botnet countries for a long time. It does not feel good for me to see my home country so high on the list. Though I detected many bots in Taiwan, which showed how effective my detection was, I really wished that Taiwan could make some progress in the war against botnets. So I am gladly surprised that Taiwan has recently dropped out of the top 10. The number of bots detected in Taiwan daily has also reduced from more than 1000 to less than 100 now. Great!
