Which term refers to software designed to cause harm or unauthorized activity on networks?

• A. Malware
• B. Local
• C. Load Balancing
• D. Managed Switch

Answer: (A)

Malware is software designed to cause harm or unauthorized activity on networks. It includes programs like viruses, worms, trojans, ransomware, and spyware that can damage systems, steal data, or take control of devices. This makes it the best description for software created with malicious intent. The other terms describe legitimate networking concepts or hardware: local refers to proximity or a local scope, load balancing distributes traffic across servers, and a managed switch is a network device with configuration and monitoring capabilities. Understanding malware helps explain why defenses focus on antivirus/anti-malware tools, regular patching, user education, access controls, network segmentation, and continuous monitoring for unusual activity.
