    Which of the following is a malicious program that infects a host computer and has the ability to replicate itself

    • Spyware

    • Virus

    • Rootkit

    • Spam

    Correct Answer
    A. Virus
    Explanation
    A virus is a type of malicious program that infects a host computer and has the ability to replicate itself. It can spread from one computer to another, often through email attachments, infected websites, or shared files. Once inside a computer, a virus can cause various harmful effects, such as deleting or corrupting files, stealing personal information, or slowing down the system. Unlike spyware, which is designed to collect information without replicating, or a rootkit, which is used to gain unauthorized access to a computer, a virus specifically focuses on self-replication and spreading to other computers.
