The first A.I. is armed with guided missles and lasers. Keep shooting at its circular hull and it will eventually explode. The spike virus comes in two strains. One takes several shots to destroy. The other is indestuctable. These viruses, which resemble spiders, hide and travel around in data packets. They are extremely dangerous. Another strain of the muncher virus. Wanted for unauthorized Net access, eating data packets, and scaring legitimate users of the Net. The 'Muncher' was one of the first viruses discovered on the 'Net'. It is relatively easy to kill.
