Spam surge drives net crime spree

The tussle between computer security companies trying to protect your PC and the bad guys that try to compromise it is often characterised as an arms race. Sometimes the security companies have the upper hand as they develop and deploy novel techniques to spot and stop malicious software of all stripes. And sometimes, such as in 2006, the bad guys are on top. And nowhere has this been more apparent than in the realm of that old favourite - spam.
