Why is the Security Center (Windows???) detected that virus monitoring software is unknown

Phenomenon

The Safety Center (Windows Security Centre, WSC) reports that the status of virus monitoring/anti-virus software is unknown.

Analysis

The unknown state reported by the Security Center also means that WSC will not be able to determine whether the virus signature library file for virus monitoring software has recently been updated and whether the local library file has been updated. and virus monitoring software only after updating the latest virus signature library can be the most effective work.
