Question 67
Identify the type of virus from below description:
● Virus has capability to change its own code to hide itself from anti-virus
● Additionally virus can use encryption to protect themselves from detection. They do this by encrypting their own code multiple times as they replicate, making it difficult for antivirus software to decrypt the code and identify the virus.
- A A. Tunneling virus
- B B. Stealth virus
- C C. Decryption virus
- D D. Hidden virus
Reveal correct answer
Correct answer: B
Explanation
Correct Answer: B. Stealth virus Explanation: A stealth virus is a type of computer virus that is designed to avoid detection by antivirus software by actively hiding itself from detection. One way it does this is by changing its own code, which makes it harder for antivirus software to identify and remove the virus. Additionally, stealth viruses can use encryption to protect themselves from detection. They do this by encrypting their own code multiple times as they replicate, making it difficult for antivirus software to decrypt the code and identify the virus. Overall, stealth viruses are particularly dangerous because they are difficult to detect and remove, and they can often remain undetected on a computer for a long time, allowing them to continue to cause damage to the system and potentially spread to other computers as well.Discussion
