Microsoft Defender for Endpoint doesn't detect renamed virus file

[ferapontov]

Microsoft Defender for Endpoint successfully detects eicar.com test virus file, however when i rename it to 123.jpg it's not detected as a virus. Is there an option in Microsoft Defender for Endpoint  which would allow recognition of renmed virus file?
