What is malware?

Malware is defined as malicious software that is specifically designed to harm, exploit, or otherwise negatively impact devices or networks. This category encompasses various forms of harmful software, including viruses, worms, ransomware, spyware, adware, and more.

These types of software can disrupt normal operations, compromise sensitive information, steal data, or gain unauthorized access to systems. Understanding malware is crucial in cybersecurity, as it directly relates to the threats faced by individuals, organizations, and networks in the digital age.

The other options describe software that serves protective, maintenance, or enhancement roles, which are fundamentally different from the intent and functionality of malware. Software that enhances device performance or provides security measures is intended to improve user experience and protect system integrity, unlike malware, which has detrimental goals.
