PetManimal writes "Symantec says that China, Russia, and the other developing countries usually blamed for the increasing amount of malware are not the biggest culprits. The security software company released a report (PDF) claiming that the US leads the world in a number of malware categories, ranging from the 'amount of malicious activity originating from their networks' to 'underground economy servers.' Preston Gralla says the US lead should come as no surprise, considering the capitalist way of life and the high level of technical knowledge. He also suggests that the some of the 'criminals' may actually be Internet entrepreneurs who crossed over to the dark side: 'It's an inevitable result of a thriving free market and tech expertise. An underground economy often mirrors the legal, above-ground one. Scratch a criminal, and sometimes you find a misguided entrepreneur, looking to get rich a little too quick.'"
