Which type of software is designed to harm or exploit computers?

• A. Antivirus software
• B. Operating system software
• C. Malware
• D. Utility software

Answer: (C)

Malware is specifically designed to harm or exploit computers and networks. This category encompasses a variety of malicious software types, including viruses, worms, trojan horses, ransomware, and spyware, all of which seek to disrupt normal operations, steal sensitive information, or gain unauthorized access to systems.

Unlike antivirus software, which actively protects against malware by detecting and removing it, malware itself operates with harmful intent, making it the correct answer to the question regarding software designed for malicious purposes. Furthermore, operating system software provides the foundational services necessary for a computer to function and run applications, while utility software is built to help manage, maintain, or optimize computer performance. These types of software serve supportive functions rather than exploitative ones.
