Networks electronic immune system: Virus = user?

WinInfo | at | by Mike

Microsoft CTO Craig Mundie says that a recent security report claiming that the company's software is too dangerous for governments is simply the work of anti-Microsoft groups and not to be taken seriously. Mundie even offered up a solution to the waves of viruses and worms that constantly affect Windows systems and, no, it didn't amount to adopting Linux. Instead, Mundie suggested that machines and networks could be rearchitected as an electronic immune system, preventing attacks from reaching the machines they're targeting. It sounds like a great idea... but it does remind me, vaguely, of the plot lines behind "The Terminator" and the "The Matrix." Once the "immune system" becomes sufficiently powerful, won't these machines simply (and accurately) determine that the biggest source of problems they face come from actual users?
