What is the definition of malware?

Malware, short for malicious software, is specifically designed to damage, disrupt, or gain unauthorized access to computer systems and networks. The emphasis is on the harmful intent behind malware, which includes a variety of forms such as viruses, worms, Trojans, ransomware, and spyware. Malware can lead to data theft, system failures, and even the exploitation of computer resources for malicious purposes.

In contrast, software that assists computer functions, protects against threats, or is used legitimately for productivity serves beneficial roles in computing. Such software includes system utilities, antivirus programs, and office productivity applications. These definitions highlight the polar opposite of malware's intent, reinforcing that the principal characteristic of malware is its goal to harm rather than help. This context underscores why the definition of malware, focused on its intent to damage or disable systems, is the most accurate and relevant.
