What is a characteristic difference between a computer virus and a computer worm?

• A. A virus can replicate itself
• B. A worm is slower than a virus
• C. A virus spreads via networks
• D. A worm does not affect files

Answer: (A)

A computer virus and a computer worm are both forms of malware, but they have distinct characteristics that set them apart. The correct choice highlights that a virus can replicate itself and requires a host program to spread, while it typically attaches itself to files or applications. Viruses need user action to propagate, such as opening an infected file, which allows them to execute and potentially spread further. In contrast, worms are designed to spread autonomously through networks without needing user intervention or a host file. This fundamental difference is crucial in understanding how each type of malware operates. The answer also clarifies that the replication mechanism of a virus involves attaching to and infecting files or programs, whereas worms disperse without direct attachment and primarily exploit vulnerabilities in network protocols or systems. Thus, the nature of self-replication and dependency on a host program is a key characteristic that distinguishes a virus from a worm.
