What is malware?

Malware is defined as malicious software specifically created to damage, disrupt, or gain unauthorized access to computer systems, networks, or devices. This encompasses various types of harmful programs, including viruses, worms, trojans, ransomware, and spyware, among others. The fundamental characteristic of malware is its intent to exploit vulnerabilities for malicious purposes, such as stealing personal information, corrupting data, or compromising system integrity.

In contrast, options describing software as enhancing computer performance or managing personal data do not align with the essence of malware, as they imply positive functions rather than harmful intent. Similarly, referring to hardware used for processing does not relate to the concept of software maliciously targeting systems, which firmly establishes the correctness of the definition centered on malicious intent within computer technology.
