What is malware, and what are some common types?

Malware refers to any software intentionally designed to cause damage to a computer, server, client, or computer network. This type of software is created to harm or exploit digital devices and systems in various ways, such as stealing sensitive information, disrupting operations, or gaining unauthorized access to systems.

The choice that accurately describes malware includes the definition of malicious software and identifies common types, such as viruses, worms, and ransomware.

Viruses attach themselves to legitimate programs and can replicate when the host program is executed, often causing damage to files and programs. Worms are similar but can spread across networks without needing to attach to other programs. Ransomware is particularly destructive, as it locks users out of their systems and demands payment for access restoration.

By identifying these commonly recognized forms of malware, the answer reflects a clear understanding of the concept and its impact on cybersecurity.
