A worm virus, or computer worm, is a type of malware that replicates itself and spreads through a network without requiring human interaction. It can exploit vulnerabilities in security software, steal sensitive information, install backdoors, and cause various harms such as consuming memory and bandwidth, deleting and modifying files, and injecting other malicious software into a device
. Unlike viruses, worms do not rely on human action to spread and can propagate independently through various means, such as email attachments, instant messages, or by exploiting network vulnerabilities
