EICAR test file - riskless method to test your antivirus and firewall solution

Disclaimer: There are more meaningful, and more advanced solutions to test your security solutions, but for a quick, simple, and riskless test, the upcoming test files are more than enough.

EICAR test file

The most common test file to test said solutions is the EICAR Anti-Virus Test File. The European Institute for Computer Antivirus Research (EICAR) and Computer Antivirus Research Organization (CARO) developed the test file, and is in the end a simple text file with a plain string of ASCII characters.

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Most solutions will prevent you from downloading it or put it into quarantine, since it will be treated as a threat. That said, some providers - for example Malwarebytes [1][2] - refused to add fake malware / test files to their database since they don't see any benefits.

More information and the download link can be found here.
