So why does the Security Center (Windows Security Center) detect that the virus monitoring software is in an unknown status? The reason why the security center (Windows Security Center, WSC) reports that the status of the virus monitoring/anti-virus software is unknown.

Analysis: The unknown status reported by the security center means that WSC will not be able to determine whether the virus signature library file of the virus monitoring software has been updated recently, and whether the local library file has been updated. Virus monitoring software can only work most effectively after it is updated with the latest virus signature database. This is why Security Center warns users about this unknown status.

Solution:

1. Update the virus signature database.

2. Contact the anti-virus software manufacturer to confirm whether the software has an upgrade package to allow SP2 Detect its online virus signature updates.

3. Purchase anti-virus software or renew its license to obtain virus signature updates.

4. Configure the security center to allow users to monitor manually its status.
