What is a virus scanner test file?

A virus scanner test file is a file designed specifically to verify virus scanners. The scanner’s detection logic reports it as a “hit”, but the file contains no real virus or malware. This lets you check that your virus scanner is working correctly – without using real malware.

The common standard for this is the EICAR test file. Almost all virus scanners know this signature and report it. dummyfiles.dev provides the EICAR test file with your choice of extension (.com, .txt, .exe, .pdf, .xls, .doc) for download and via API.

Testing your virus scanner reliably

After installing a virus scanner or after updates, many users want to confirm that detection works. A virus scanner test file gives a clear result: if the file is detected and optionally moved to quarantine, the scanner is working as expected. If the test file is not detected, that may indicate configuration or installation issues.

FAQ

Is the virus scanner test file dangerous?

No. It is the harmless EICAR test file – text only, no executable code.

Why does my virus scanner detect the file?

Virus scanners are configured to report the EICAR signature so you can test detection.

How do I test my virus scanner?

Download the virus scanner test file from dummyfiles.dev or call the API. If the file is detected (or moved to quarantine), the scanner is working.
