Why does a worm pose a greater threat than a virus poses?

• Worms are more network-based than viruses are.
• Worms are not detected by antivirus programs.
• Worms run within a host program.
• Worms directly attack the network devices.

Explanation: One major component of a worm is the propagation mechanism which replicates the worm and targets unprotected network devices. A virus requires a host program, but worms do not.
