Testing to see if AV scanning is working can be done very simply by using the industry approved EICAR test file. This file is a simple text string that is a valid Windows executable and that all AV vendors will recognize as a virus for test purposes.
Open Event Viewer in Windows, then navigate to Applications and Services Logs, Microsoft, Windows, Windows Defender, and Operational. The following warning message indicates that the CAVA anti-virus software has detected this EICAR testing virus.
Note: The path in the Event Viewer should always start with file:\\<fqdn_of_cluster>\CHECK$\.
