what is worms malware

A computer worm is a type of malware that can replicate itself and spread to other computers while remaining active on infected systems. It can propagate across a network through various means such as email attachments, phishing, and network vulnerabilities. Worms can be harmful, causing a range of attacks including system crashes, data theft, and backdoor access to equipment. They are distinct from viruses and Trojan horses, and they can be challenging to remediate. Worms are designed to self-replicate and consume system resources, and they can also be used in ransomware attacks. Unlike viruses, worms do not always attempt to change the systems they pass through, and they can spread without human intervention. They can be transmitted through vulnerabilities in software, email attachments, instant messages, and spam emails
