Question

• A. A-III, B-II, C-IV, D-I
• B. A-II, B-III, C-IV, D-I
• C. A-II, B-III, C-I, D-IV
• D. A-III, B-IV, C-I, D-II

Hint:

The key distinction between a virus and a worm is:
- Virus = Needs a host program to attach to and propagate.
- Worm = Standalone, spreads automatically across networks without a host.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question requires matching different types of malicious software (malware) listed in List-I with their corresponding definitions or behavioral descriptions listed in List-II.

Step 2: Key Concepts of Malware Types:
- Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network.
- Different malware classes are distinguished by how they replicate and their target objectives.

Step 3: Detailed Explanation of Matching:
- A. Worms: A computer worm is a self-replicating program. Unlike a virus, it is a standalone application and does not need to attach itself to an existing host file or program to spread. Thus, A matches with II.
- B. Virus: A computer virus attaches its malicious code to an executable host file or document. It replicates and infects other files or systems when the compromised host file is shared or run. Thus, B matches with III.
- C. Adware: Short for advertising-supported software. It automatically displays or downloads advertising material (such as banners or pop-ups) to generate revenue, often on a pay-per-click basis. Thus, C matches with IV.
- D. Spyware: This software is installed clandestinely to monitor and gather information about a user's activities (such as keystrokes, browsing history, and credentials) and transmit it to third parties or advertisers. Thus, D matches with I.
- Combining these matches: A-II, B-III, C-IV, D-I.

Step 4: Final Answer:
The correct matching sequence is A-II, B-III, C-IV, D-I.
Hence, option (B) is the correct choice.
