Final answer:
A worm is a type of malware designed to replicate itself and create excessive network traffic, which can lead to network slowdowns and disruptions.
Step-by-step explanation:
Malware that works to create a lot of network traffic is referred to as a worm. A worm is a type of malware that replicates itself in order to spread to other computers, often over a network. Unlike viruses, which typically corrupt or modify files on a target system, worms usually consume bandwidth and cause performance degradation by creating excessive network traffic. This can result in network slowdowns and disruptions of regular activities. It's important to use robust antivirus software and practice good cybersecurity habits to prevent worm infections.
