I can see why someone would want to study virii and trojans and better understand the vulnerabilities of their systems. But, what I don't understand is what kind of thrill a person gets from sending virii out to people they don't even know. In the right hands I guess there could be uses for trojans. Like to monitor a suspected cheating spouse....or to keep track of what your "skript kiddie" has been doing online. I imagine there are many so called legitamate cases where someone would jusify themselves using a trojan...or getting revenge with a virus, but whats up with those people who send them out at random for malicious intent?
