Zombie Computer Armies
Botnets. You may not have heard of them, but their invisible nature makes them all the more dangerous. And you may already be both a victim and an accomplice in a botnet operation. Because everything in the high-tech world needs an acronym or abbreviation, a botnet is actually short for a robot network. Think of it as a massive super-computer army with your computer one of the many conscripted ranks.
