A worm is a type of malware that can replicate itself and spread from one computer to another. Worms often exploit vulnerabilities in software to gain access to systems and can cause a variety of damage, including data theft, system crashes, and network outages.
Worms are a major threat to computer security, and it is important to take steps to protect your systems from infection. These steps include keeping your software up to date, using a firewall, and being careful about what attachments you open in emails.
