Which of the following is considered a form of malware?

• A. Antivirus software
• B. Spyware
• C. Firewalls
• D. Operating systems

Answer: (B)

Spyware is classified as a form of malware because it is designed to infiltrate a computer system without the user's consent, gathering and transmitting personal information through their internet activity. This type of malicious software can capture sensitive data, such as login credentials and financial information, which poses significant privacy and security risks to users. Spyware operates stealthily, often making it difficult for users to detect its presence and effects.

In contrast, antivirus software is specifically created to identify, block, and remove malware, serving an important protective function against threats like spyware. Firewalls act as barriers that control incoming and outgoing network traffic based on predetermined security rules, thereby also preventing unauthorized access and potential malware infections. Operating systems provide the foundational software that manages hardware and software resources on a device but are not classified as malware themselves.
