What distinguishes a computer worm from a computer virus?

• A. A worm does not replicate
• B. A worm requires user intervention to spread
• C. A worm actively tries to move within the system
• D. A worm is less harmful than a virus

Answer: (C)

A computer worm is distinguished from a computer virus primarily by its ability to independently replicate and spread across networks without the need for user intervention. While both worms and viruses are malicious software, a worm actively exploits vulnerabilities in a network or system to propagate itself, often without any actions taken by the user. This means that once a worm is in one system, it can automatically seek out and infect other systems, leading to rapid dissemination. In contrast, viruses typically require a user to execute a specific action, such as opening a file or running a program, to initiate the replication process. The self-propagating nature of worms is what typically causes significant network congestion and security challenges, as it can lead to widespread infection and damage without direct human engagement. Understanding this fundamental difference is crucial for distinguishing between various types of malware and for implementing effective cybersecurity measures.
