At this point, evidence seems to indicate the 'bot masters are now using
lots of small 'bot nets instead of large ones. The reasoning is that if one
net is uncovered, they only lose a small percentage of their total.
It also makes detecting these nets much more difficult.
One should take the Symantec report with a grain of salt. I believe
the total number of PCs running 'bots and the number of 'bot nets continues
to grow, but the number of 'bot nets actually detected is shinking.
