Which of the following best describes malware?

The best description of malware is that it is software designed to damage or gain unauthorized access to computer systems. Malware encompasses a variety of malicious software types, including viruses, worms, Trojans, ransomware, and spyware, all of which are crafted with the intent of causing harm, stealing sensitive information, or exploiting system vulnerabilities.

When analyzing the nature of malware, the focus is on its malicious intent and capabilities. Malware operates covertly, often without the user's knowledge, seeking to disrupt normal operations or infiltrate networks for malicious purposes. This can include actions such as data theft, system damage, or unauthorized surveillance.

In contrast, legitimate programs that perform useful tasks are not categorized as malware. Security tools used for protection are designed to prevent or mitigate threats, while file compression utilities serve a benign purpose in managing file sizes. Understanding the distinguishing characteristics of malware assists in recognizing its potential threats and the need for cybersecurity measures to combat it.
