Which action is a benefit of running regular antivirus scans?

• A. Reduces disk space usage.
• B. Eliminates the need for anti-malware signatures.
• C. Detects malware that real-time protection might miss.
• D. Disables firewall.

Answer: (C)

Regular antivirus scans provide a thorough verification pass that complements real-time protection by inspecting the entire system for threats, including those that might hide or stay dormant. Real-time protection watches for suspicious activity as files are opened or executed, but it can miss malware that is dormant, deeply embedded, or cleverly disguised. An on-demand scan uses up-to-date signatures and heuristics to systematically check files, archives, and system areas that real-time monitoring may not scrutinize every time, increasing the chance of catching malware that would otherwise slip through. This is why detecting malware that real-time protection might miss is the best answer. The other options aren’t benefits of running scans: they don’t reduce disk space usage, they don’t eliminate the need for anti-malware signatures (scans depend on those definitions and updates), and they don’t involve disabling the firewall.
