In the most extreme cases, the worms affected computer networks around the world and drastically slowed down the network.

Exploitation Nature: Worms usually exploit vulnerabilities in operating systems and spread via e-mail or other document transfer functions found on network computers. They often hide in elements of operating systems that are automatic and usually invisible to you. Computer viruses and Worms are often noticed only if their uncontrolled replication consumes significant system resources, slowing down or stopping other tasks.

How worms Damages: Many worms have been produced simply for spreading and are not trying to ruin the computers they pass by. "Payload" is a piece of code that is usually created to cause harm - it can delete files from your computer, encrypt files as part of extortion, or connect to outgoing e-mail.
