The EICAR Standard Anti-Virus Test file is a special 'dummy' file which is used to test the correct operation of anti-virus products. When an EICAR test file is downloaded or scanned, ideally the anti-virus product will detect it exactly as if it were a malicious program. The EICAR test file is normally used to:

  • Confirm the anti-virus application is installed and functioning correctly
  • Observe the product's actions when a malicious program is found
  • Check internal procedures and reactions when a malicious program is found

Users who would like to check the correct operation of their F-Secure Anti-Virus products can download the EICAR test file from the following links:

Alternatively, to create an EICAR test file, use any text editor to create a file with the following single line in it:


Save the file with any name using a COM extension; for example, EICAR.COM. Make sure you save the file in standard MS-DOS ASCII format. Now you can use this file to demonstrate what occurs when a virus is detected.

When executed, the EICAR test file will simply display the text "EICAR-STANDARD-ANTIVIRUS-TEST-FILE!" and exit.
