The problem with diagnosing cancer is this: you rarely feel pain until it's too late. You have unexplained weight loss that you welcome. You tire easily. You slow down a bit and adjust but you often don't feel that bad. And when you finally feel pain, it's often too late.

The botnet problem shows no sign of easing. Security firm Damballa pinpointed 7.3 million unique instances of bots carrying out nefarious activities on an average day in January - an astronomical leap from a daily average of 333,000 in August 2006. That included botnet-delivered spam, which accounted for 91% of all e-mails in early March, up from 64% last June, says e-mail management firm Cloudmark.
