Is there a virus test I could use to test MetaDefender Core v4?

Tests to determine an engine's operation are rarely run with live malware. The suggested approach to test is to use an industry-standard test file called an EICAR Test File, which most antivirus engines detect as positive even though no threat exists.

An EICAR Test File can be downloaded from You can also create your own version of the file by copying the following string into a file and renaming it to "":

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H* For more information about the EICAR Test File, please visit the European Expert Group for IT-Security's website.
