System health report doesn't detect antivirus programs in Windows 7

Symptoms

If you generate a system health report on a Windows 7-based computer, the system health report reports that no antivirus program is installed on the computer even when an antivirus program is installed. This means that you can’t use the system health report in a domain environment to determine which computers do not have an antivirus program installed.


Additionally, the following message is in the report:

Symptom: The Security Center has not recorded an anti-virus product.
Cause: The Security Center is unable to identify an active anti-virus application. Either there is no anti-virus product installed or it is not recognized.
Resolution: 1. Verify that an anti-virus product is installed. 2. If an anti-virus product is installed and functioning configure Security Center to stop monitoring anti-virus status.

Cause

This issue occurs because the system health report engine uses an incorrect Windows Management Instrumentation (WMI) namespace to query information about installed antivirus applications.

Resolution

Note This hotfix uses a new Windows Management Instrumentation (WMI) namespace and only lets you verify the presence of an installed antivirus product. The product state cannot be reported.

    Version

    Product

    Milestone

    Service branch

    6.1.760
    0.20xxx

    Windows 7

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
