As it is built into the OS, MDAV has different running modes to provide compatibility with other endpoint protection software. If no other antimalware service is running, normal mode is used, and MDAV provides its configured threat protection capabilities.
In the presence of a third-party service for endpoint protection, MDAV can enter passive mode. This is only an option if the device is onboarded to MDE: consumer or unlicensed devices cannot leverage it, and instead use disabled mode.
