    A worm is also considered a subclass of virus?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A worm is considered a subclass of a virus because both are types of malicious software that can infect computer systems. However, there are some differences between the two. A virus needs a host file or program to attach itself to, while a worm is a standalone program that can spread itself across networks without needing a host. Additionally, worms are usually designed to exploit vulnerabilities in computer systems to spread rapidly, whereas viruses often rely on user actions to propagate. Despite these differences, both worms and viruses can cause significant harm to computer systems and are considered types of malware.

    Rate this question:

  • 19. 

    A worm cannot:

    • A.

      Look similar to the virus

    • B.

      Can travel from computer to computer

    • C.

      Can replicate itself into a large amount of worms and spread itself fast.

    • D.

      Can reduce the virus threat

    Correct Answer
    D. Can reduce the virus threat
    Explanation
    A worm is a type of malware that can travel from computer to computer and replicate itself into a large number of worms, spreading itself quickly. However, it cannot reduce the virus threat. Worms are designed to exploit vulnerabilities in computer systems and networks, but they do not have the capability to actively reduce or eliminate other types of malware, such as viruses. Therefore, the statement "can reduce the virus threat" is not true for worms.

    The kind of virus that infects and spreads in multiple ways is called macro virus.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is incorrect. The kind of virus that infects and spreads in multiple ways is not called a macro virus. Macro viruses are a type of virus that infects files created using certain applications, such as Microsoft Office, and use the application's own macro programming language to execute malicious actions. However, there are other types of viruses, such as file infectors and network viruses, that can infect and spread in multiple ways. Therefore, the correct answer is False.
