  Korgo.A
Korgo.A is a Worm. Worms are reproducing malicious programs that run independently and travel across network connections without human action. They could spread over email, IM, peer-to-peer networks, or directly over the wire by leveraging vulnerabilities. The threat that a worm poses is its capability to replicate itself on the system so the computer can send out hundreds or thousands of copies of itself.
