EICAR Test File
The purpose of the EICAR test file is to provide an industry standard solution to the following questions:
The idea is that anti-virus programs detect the file exactly like they detect viruses, and treat it as one - for example as a 78-byte overwriting virus (when disinfecting).
The same purpose would of course be served by a custom test file for each program, but this may simplify the testing process, in particular when multiple products are being tested and evaluated.
The EICAR test file looks like this:
and should be saved to a file with a .COM extension (EICAR.COM being the most obvious choice).
When run, it will display the string "EICAR-STANDARD-ANTIVIRUS-TEST-FILE!".
As a side note, the file is made printable so that it can easily be printed in a manual, included in the documentation, dictated over the phone or sent by fax. It is not recommended that the file be included "stand alone" in the anti-virus package in "binary form", as users might run the anti-virus program on the package before realizing what the file is for.
The EICAR test file is the result of a cooperative effort between various anti-virus researchers. It is not vendor specific and is being made available free of charge.
