Which of the following is a defense in cybersecurity?

• A. Antivirus software detects and deletes malicious software
• B. Ignoring security warnings
• C. Disabling firewalls
• D. Using weak encryption

Answer: (A)

Defenses in cybersecurity involve tools and practices that protect systems from threats. Antivirus software is a classic defense because it actively looks for malicious programs, detects them, and removes them or quarantines them before they can cause harm. By scanning files, monitoring behavior, and using virus definitions, it reduces the chances of infection and limits damage. Ignoring security warnings, disabling firewalls, and using weak encryption all undermine protection rather than defending it. Ignoring warnings leaves systems vulnerable to known threats; disabling a firewall removes a barrier that blocks unauthorized access; weak encryption can be easily broken, exposing data. So antivirus software embodies a protective, active safeguard.
