What is malware?

Malware, short for "malicious software," refers specifically to software that is intentionally designed to cause harm, exploit, or compromise the integrity of computer systems, networks, or devices. This encompasses a wide range of harmful programs, including viruses, worms, trojan horses, ransomware, and spyware. The primary purpose of malware is to disrupt normal operations, steal sensitive information, gain unauthorized access to systems, or otherwise harm users and their devices.

Understanding the nature of malware is crucial for recognizing the threats that exist in the digital landscape. In contrast, the other options describe elements that are not related to malware. For instance, options that mention computer hardware or performance-enhancing software do not pertain to the malicious intent that characterizes malware. Antivirus programs, while important for protecting against malware, are designed to detect and remove malicious software rather than being classified as malware themselves.
