Which of the following best describes malware?

Malware refers to malicious software that is specifically designed to infiltrate, damage, or disrupt computer systems, networks, or devices. It encompasses a broad range of harmful programs, including viruses, worms, trojans, ransomware, and spyware. The primary purpose of malware is to exploit vulnerabilities in systems for various nefarious intents, such as stealing sensitive information, gaining unauthorized access, or causing damage to systems.

The other options describe software that does not fit the definition of malware. For instance, software created for educational purposes is intended to enhance learning, while tools aimed at improving system performance or performance monitoring software are designed to optimize system efficiency and functionality, not to cause harm or exploit vulnerabilities.
