Klez: Hi Mom, We're No. 1

"Klez managed to triple its annoyance factor by using -- yes, using -- the AV industry," [Rod] Fewster [of NOD32] said. "AV companies have been exploiting those auto-replies as free advertising for years. Virus spreaders aren't stupid. They see what's going on around them and they work the system. Sometimes I think the antiviral industry is its own worst enemy."

Clever people, these virus makers.
