Which term describes scanning email for threats via the POP3 protocol?

• A. Heuristics
• B. Email Antivirus
• C. Web Browsing Antivirus
• D. Threats to Detect

Answer: (B)

Scanning email for threats through POP3 is best described as Email Antivirus. POP3 is the protocol used to retrieve email from a mail server, so an email antivirus focuses on inspecting messages—attachments and content—as they arrive or are fetched, to detect and block malware or malicious payloads before the user opens them. While heuristics are a detection technique used inside antivirus engines, the term that captures this email-specific protection is Email Antivirus. Web Browsing Antivirus covers threats from websites, not email traffic, and the phrase Threats to Detect isn’t a standard term for this function.
