Suspected Computer-Virus Author Arrested

T0rn, with a zero, was not as menacing as the Code Red, Sircam and Nimda worms and viruses, which caused hundreds of millions of dollars in damage to corporate computer networks last year. Linux-based software systems account for a small segment of the computing market.
