Maybe someone can explain to me how these fellows profit off of spam.
LarryC: If a lot of spam comes via botnets, could the drop be due to some Windows security update?Here is some optimistic and groundless pure speculation: It could be that the oldest, cruftiest, most infected Windows XP machines are steadily being replaced with Windows 7 machines, and that the botnet software doesn't work so well on Windows 7. (Yet. Or maybe never; it is intended to be more secure.) Windows 7 adoption has been on a tear since summer, which corresponds suggestively with the recent downward trend in spam. And one might expect to see a surge in Windows 7 use (and a corresponding fall in bot-net activity) in December, when new computers fly off the shelves as gifts or at Black Friday type sales.
