Novel computer viruses and worms can sweep the world within hours, leaving a trail of devastation, because firewalls and antiviral software work by identifying the telltale signatures of known attacks.

The company is testing the technique with the help of the US Army's Computer Crimes Investigation Command in Fort Belvoir, Virginia. |
