What does the term "malware" encompass?

The term "malware" encapsulates any software that is created with the intention to disrupt, damage, or gain unauthorized access to computer systems, networks, or devices. This broad definition includes a variety of malicious software types, such as viruses, worms, ransomware, spyware, adware, and other threats that aim to exploit vulnerabilities.

Option B is correct because it accurately reflects the essence of malware as software specifically designed to inflict harm or take advantage of systems. The comprehensive nature of this definition is crucial, as it demonstrates that malware is not limited to just one type or method of operation; it includes any malicious code that compromises security or functionality.

The other choices do not align with the broader definition of malware. For instance, describing malware as solely a personal use tool or as a specific type of encryption software fails to capture its harmful intent. Additionally, limiting malware to just viruses and trojans overlooks the various other forms of malicious software that also fall under the malware category, which is why the second option stands out as the most accurate representation.
