Which of the following accurately defines a "malware"?

Malware is defined as software that is specifically created to disrupt, damage, or gain unauthorized access to computer systems, networks, or devices. This definition encompasses a wide range of malicious software, including viruses, worms, trojan horses, ransomware, and spyware, all of which have harmful intentions, such as corrupting data, stealing personal information, or causing operational disruptions.

By specifying that malware is intended to disrupt or damage systems, the definition highlights the primary purpose and malicious nature of such software. This is crucial in understanding the risks associated with cybersecurity and the importance of implementing protective measures against these threats.

The other options reference software that serves beneficial purposes rather than malicious ones, focusing on improving performance, enhancing user experience, or preventing unauthorized access. These descriptors do not align with the primary characteristics associated with malware, which is inherently destructive or intrusive in nature.
