Which option lists a basic defense that applies across common malware categories such as viruses, worms, Trojans, and ransomware?

• A. Relying on a single firewall
• B. Disabling automatic updates
• C. Regular antivirus software, patching, user training, and backups
• D. Using default passwords

Answer: (C)

Across common malware categories, a basic defense is defense in depth: combining regular antivirus software, timely patching, user training, and reliable backups. Antivirus helps detect and remove malware like viruses and worms and can catch many Trojans, while patching closes vulnerabilities that attackers exploit to deliver or run malware. User training reduces the chances of falling for phishing or social engineering that introduce Trojans or ransomware, and backups let you recover quickly if ransomware encrypts data or other malware causes damage. The other options miss broad coverage: relying on a single firewall doesn’t address threats that enter through other means, disabling automatic updates leaves systems unpatched, and using default passwords creates easy access points and doesn’t deter malware delivery. Together, these practices provide a comprehensive, cross-category defense.
