Which statement accurately describes the EICAR test file?

• A. It is a real malware sample used to test detection.
• B. It is a harmless, standard test file used to verify antivirus functionality.
• C. It is a weaponized macro used to bypass security.
• D. It is an encrypted payload used for ransomware simulations.

Answer: (B)

The main idea is that the EICAR test file is a safe, standard artifact used to verify that antivirus software is actually detecting and responding to threats. It isn’t malware at all; it’s a deliberately harmless file that contains a specific sequence recognized by many antivirus engines as a test signal. By placing or opening this file, you can confirm that scanning is active and that the protection will alert, quarantine, or block as expected without risking infection. This is why it’s used to validate antivirus functionality across systems. The other descriptions describe real threats or malicious techniques, which the EICAR file is designed to avoid.
