Canary
Popular term for one of the many electronic devices used to test whether recovered technology is infected by the Virus. The basis of the canary is a very high-speed computing system into which a virus egg can quickly expand and develop to the point where its activity can be detected. The presence of certain type of activity can easily be detected as the virus attempts to "reach out" of the canary to manipulate other objects. Some actually have a mechanical arm that waves a flag to show the developing virus is testing its parameters, "stretching it legs" as it were. It is not unknown for salvage crews to create pools to bet on "when it waves to us".
The canary is so named because many of the early versions actually "died" if they were exposed to the Virus, showing the tested equipment was indeed infected.
