Correct Answer
C. It is a program that meets three essential characteristics. harmful, surreptitious, self-reproducingExplanation
A virus is a type of program that meets three essential characteristics: harmful, surreptitious, and self-reproducing. This means that a virus is designed to cause damage to a computer system or data, it operates in a hidden or secretive manner, and it has the ability to replicate and spread itself to other files or systems. These characteristics distinguish a virus from other types of programs.Rate this question:

A virus is surreptitious when........
- A.
It disapears
- B.
It loads
- C.
It works in a hidden manner
- D.
It destroys everything it finds
Correct Answer
C. It works in a hidden mannerExplanation
A virus is considered surreptitious because it operates in a hidden manner, without the knowledge or detection of the user. It works discreetly, often disguising itself as legitimate software or hiding within the system, making it difficult to identify and remove. This stealthy behavior allows the virus to carry out its malicious activities, such as stealing sensitive information or causing damage, without being noticed by the user or antivirus programs.Rate this question:

- B.
Reproductive, attack, defense
- C.
Reproduce, clone, forward
- D.
Transform, create, design
Correct Answer
B. Reproductive, attack, defenseExplanation
A virus is made up of three modes: reproductive, attack, and defense. The reproductive mode allows the virus to replicate and create copies of itself within a host organism. The attack mode enables the virus to invade and infect host cells, causing harm and spreading the infection. The defense mode helps the virus evade the host's immune system and protect itself from being destroyed.Rate this question:
