If every computer only infected 2 other computers and stopped, you'd still
eventually get hundreds of connection attempts to firewalls

. The only way
it could spread undetected is if nobody noticed connection attempts, the
vulnerability wasn't known by anyone and nobody noticed a foreign program
running on their computer.
