Detailed explanation-1: -A computer worm is a subset of the Trojan horse malware that can propagate or self-replicate from one computer to another without human activation after breaching a system. Typically, a worm spreads across a network through your Internet or LAN (Local Area Network) connection.

Detailed explanation-2: -The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.

Detailed explanation-3: -A computer worm is a type of malware whose primary function is to self-replicate and infect other computers while remaining active on infected systems. A computer worm duplicates itself to spread to uninfected computers.

Detailed explanation-4: -A worm is a type of malware that can copy itself and often spreads through a network by exploiting security vulnerabilities. It can spread through email attachments, text messages, file-sharing programs, social networking sites, network shares, removable drives, and software vulnerabilities.

Detailed explanation-5: -The strictest definition of a “network virus” describes a relatively new type of malware that spreads from computer to computer without having to drop a file-based copy of itself in any of the affected computers. These viruses exist only as network packets, when they move from one computer to another, and in memory.
