Jose's numbers are conservative.
Given some mathematical acrobatics, I'd suggest examining some of the (shocking) number sin Microsoft's Security Intelligence Report (Google it) -- these are reflective:
"Of the 4 million computers cleaned by the company's MSRT (malicious software removal tool), about 50 percent (2 million) contained at least one backdoor Trojan. While this is a high percentage, Microsoft notes that this is a decrease from the second half of 2005. During that period, the MSRT data showed that 68 percent of machines cleaned by the tool contained a backdoor Trojan."

If you're wondering why DDoS attacks are so effective, look no further than your backyard.

Jose may be a bit conservative with numbers, but he has good data and shares it, which is more than I can say for some people. Jose is definitely someone who knows what he is talking about when it comes to botnets. These numbers are not really relevant in my opinion, but they help get the message across. Gadi.
