    other software programs?
    A Stealth Virus Correct Answer Incorrect Answer
    B Trojan Horse Correct Answer Incorrect Answer
    C Worm Correct Answer Incorrect Answer
    D Cluster Virus Correct Answer Incorrect Answer
    E Macro Virus Correct Answer Incorrect Answer

    Solution

    A cluster virus is a type of malware that modifies system directory or registry entries so that when a program is launched, the virus executes first. This allows the virus to spread while remaining hidden.
    On the other hand, worms are self-replicating malware, and Trojan horses disguise themselves as legitimate software to deceive users.
