Which type of malware is designed to replicate itself and spread to other computers?

The type of malware specifically designed to replicate itself and spread to other computers is a worm. Unlike other types of malware, worms have the unique capability to propagate independently over networks without requiring any human interaction or additional software. This makes them particularly dangerous, as they can rapidly infect numerous devices, leading to extensive damage and disruption before users are even aware of the infection. Worms often exploit vulnerabilities in operating systems or applications to gain access, replicate, and then transmit themselves across connected systems. This self-replicating characteristic distinguishes worms from other forms of malware, such as Trojans, spyware, and adware, which typically require some form of user action or specific conditions to spread.
