The definition of "malware" is accurately captured as malicious software designed to harm a computer or its users. Malware is a broad category that encompasses various types of harmful software, including viruses, worms, spyware, ransomware, and Trojan horses. Each of these forms of malware serves the purpose of disrupting operations, stealing personal information, gaining unauthorized access to systems, or otherwise causing damage.

Understanding this term is crucial for IT professionals, as the presence of malware can significantly affect the security and integrity of systems. Being able to identify and mitigate the risks associated with malware helps protect both organizational and personal data from cyber threats.

The other options do not fit the definition of malware. While the first choice refers to software that defines system functionalities, which could include legitimate tools and applications, it does not denote malicious intent. The third choice pertains to programs designed to enhance performance, which is also not relevant to malware's harmful nature. Lastly, the fourth option discusses code that runs on servers but fails to address the malicious aspect that characterizes malware. Thus, the identification of malware as malicious software is clear and distinguishes it from other types of software.
