    Which virus infects program files like having an ".EXE" extension?

    • A. 

      Boot Virus

    • B. 

      Trojan Horse

    • C. 

      Program Virus

    • D. 

      Malware

    Correct Answer
    C. Program Virus
    Explanation
    A program virus is a type of virus that infects program files with an ".EXE" extension. This means that when a user runs an infected program, the virus will also execute and potentially cause harm to the system. Unlike boot viruses, which infect the boot sector of a computer's hard drive, program viruses specifically target executable files. Trojan horses and malware are also types of malicious software, but they may not necessarily infect program files exclusively.

    The trojan is actually programmed to pass the user's data to someone else.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    The correct answer is "True" because a trojan is a type of malware that disguises itself as a legitimate program but actually performs malicious actions, such as stealing and transmitting the user's data to another person or entity without their knowledge or consent. Therefore, the statement accurately describes the behavior of a trojan.

    When the virus attacks, the computer applications run normally.

    • A. 

      True

    • B. 

      False

    Correct Answer
    B. False
    Explanation
    When a virus attacks, it can disrupt the normal functioning of computer applications. It can cause them to crash, freeze, or behave erratically. Therefore, the statement that computer applications run normally when the virus attacks is false.

    Which program spreads itself by means of the network?

    • A. 

      Worms

    • B. 

      Trojan Horse

    • C. 

      Spyware

    • D. 

      Spybots

    Correct Answer
    A. Worms
    Explanation
    Worms are a type of malicious software that can spread themselves through computer networks without any user interaction. Unlike viruses, worms do not need to attach themselves to a host program or file to propagate. Instead, they can independently replicate and spread across a network, infecting other computers and devices. This makes worms a particularly dangerous and fast-spreading form of malware.

    • A. 

      Spybots

    • B. 

      Spyware

    • C. 

      None of them

    • D. 

      Both i & ii

    Correct Answer
    D. Both i & ii
    Explanation
    Both i & ii refers to Spybots and Spyware. Spybots and Spyware are both types of tracking software that can be used to monitor and track activities on a computer or device. Spybots are specifically designed to collect information without the user's knowledge or consent, while Spyware is a broader term that encompasses any software that is designed to gather information about a person or organization without their knowledge. Therefore, the correct answer is Both i & ii.

  • 9. 

    The database of viruses that antivirus software scans for

    • A. 

      Computer virus

    • B. 

      Virus Definitions

    • C. 

      Program virus

    • D. 

      None of them

    Correct Answer
    B. Virus Definitions
    Explanation
    The correct answer is "Virus Definitions" because antivirus software relies on a database of known viruses to identify and remove malicious software from a computer. These virus definitions contain specific information about the characteristics and behavior of different viruses, allowing the antivirus software to detect and eliminate them. Without regularly updated virus definitions, antivirus software would not be able to effectively protect against new and emerging threats. Therefore, the database of viruses that antivirus software scans for is referred to as "Virus Definitions".

    Which type of virus infects data files?

      Macro Virus

    • B. 

      Program Virus

    • C. 

      Boot Virus

    • D. 

      Spam

    Correct Answer
    A. Macro Virus
    Explanation
    A macro virus is a type of virus that infects data files. Unlike other viruses that typically infect executable files, macro viruses infect files that contain macro code, such as documents or spreadsheets. When these infected files are opened, the macro virus is activated and can spread to other files on the system. This type of virus is often spread through email attachments or shared files, and can cause damage by corrupting or deleting data.
