Antivirus programs must be capable of which of the following?

• A. Detect all known types of malicious software
• B. Remove all known types of malicious software
• C. Protect against all known types of malicious software
• D. Detect, remove, and protect against all known types of malicious software

Answer: (D)

Antivirus software is meant to handle the full lifecycle of malware on a system: it should detect threats, remove them, and provide ongoing protection to prevent future infections. The best choice captures all three functions—detecting known malware, cleaning it up (removal), and continuing to guard the system against known threats through updates and real-time protection. Relying on just detection or just removal, or on protection alone, leaves gaps in security. Detection finds the threat, removal cleans it, and protection helps stop reinfection and new threats from taking hold.
