Getting the installed Antivirus, AntiSpyware and Firewall software using Delphi and the WMI

14 Comments

The WMI allow you to get the installed Antivirus, AntiSpyware and Firewall (third party)  software using the root\SecurityCenter or the root\SecurityCenter2 namespaces and the AntiVirusProduct , AntiSpywareProduct, FirewallProduct classes.

First you must know which these classes and namespaces are not documented by Microsoft and only are supported in Windows Desktops editions (Windows XP, Windows Vista and Windows 7).
Now depending of the Windows version the properties retrieved by the the same class can change. this is a summary of the classes and properties availables depending of the windows version

Windows XP

Namespace : SecurityCenter
Classes availables: AntiVirusProduct, FirewallProduct

AntiVirusProduct-Properties

  • companyName
  • displayName
  • enableOnAccessUIMd5Hash
  • enableOnAccessUIParameters
  • instanceGuid
  • onAccessScanningEnabled
  • pathToEnableOnAccessUI
  • pathToUpdateUI
  • productUptoDate
  • updateUIMd5Hash
  • updateUIParameters
  • versionNumber

FirewallProduct-Properties

  • companyName
  • displayName
  • enabled
  • enableUIMd5Hash
  • enableUIParameters
  • instanceGuid
  • pathToEnableUI
  • versionNumber

Windows Vista and Windows 7

Namespace : SecurityCenter2
Classes availables : AntiVirusProduct, AntiSpywareProduct, FirewallProduct

AntiVirusProduct, AntiSpywareProduct, FirewallProduct – Properties

  • displayName
  • instanceGuid
  • pathToSignedProductExe
  • pathToSignedReportingExe
  • productState

This is a sample project which determine the Antivirus, AntiSpyware and Firewall software installed in the system.

    finally
      CoUninitialize;

 except
    on E:Exception do
    begin
        Writeln(E.Classname, ':', E.Message);
        Readln;
    end;
  end;
end.

And here is the result of the app.

  2. very good to have Delphi coming back to scene with this beatiful code. Simply delicious.

  3. Hi Rodrigo,

    As usual, very good examples and great stuff on your blog. I’ve run the code provided (I work on Delphi 7) , and there were some variable and consts that were missing:

    on type section
    OSVERSIONINFOEX = packed record
    dwOSVersionInfoSize: DWORD;
    dwMajorVersion: DWORD;
    dwMinorVersion: DWORD;
    dwBuildNumber: DWORD;
    dwPlatformId: DWORD;
    szCSDVersion: array[0..127] of Char;
    wServicePackMajor: WORD;
    wServicePackMinor: WORD;
    wSuiteMask: WORD;
    wProductType: BYTE;
    wReserved: BYTE;
    end;

    DWORDLONG = UInt64;

    and the consts:

    VER_MINORVERSION = $0000001;
    VER_MAJORVERSION = $0000002;
    VER_SERVICEPACKMINOR = $0000010;
    VER_SERVICEPACKMAJOR = $0000020;
    VER_PRODUCT_TYPE = $0000080;

    in rest the example works like a charm.

    Best regards,
    Radu

  4. Hola Rodrigo:

    Fantastico, pero falta la seccion de detección de antispyware

    case SCProduct of
    :AntiSpywareProduct …

    en mi xp en el espacio de nombres de SecurityCenter no aparece
    ninguna clase que utilizar, por lo demas como decia esta fantastico.

    Felicitaciones

    Alfredo

    • vale, me respondo a mi mismo, como dices AntiSpywareProduct solo esta disponible
      para vista y windows 7 bajo SecurityCenter2

      me imagino que el codigo que falta sería algo asi:

      AntiSpywareProduct :
      begin
      //Writeln(Format(‘Fabricante %s’,[FWbemObject.companyName]));
      Writeln(Format(‘Nombre del Producto %s’,[FWbemObject.displayName]));
      Writeln(Format(‘version %s’,[FWbemObject.versionNumber]));
      //Writeln(Format(‘Activo %s’,[FWbemObject.enabled]));
      Writeln(Format(‘Instancia Guid %s’,[FWbemObject.instanceGuid]));
      Writeln(Format(‘Path Exe Firmado %s’,[FWbemObject.pathToSignedProductExe]));
      Writeln(Format(‘Path Exe firmado para reportes %s’,[FWbemObject.pathToSignedReportingExe]));
      end;

      gracias de nuevo

  5. hola
    gracias por el articulo!!!
    no me detecta el firewall propio de windows 7
    que significa “product state” 393472? como se si esta activo o no y puede interferir en mi instalador?

    Gracias! DAniel

  6. Hi, I can not see anything for firewallinfo on my Windows7 computer. The built-in windows firewall enabled. Does any trick exists that I am missing? Best regards.

  7. Hi guys,

    I’ve developed a Delphi web server that allows the users to upload files; in order to keep the server free of viruses, I’d like to check every single file the users load. Is there a way to call the “file scan process” of the default antivirus by using WMI ¿?

    thanks very much in advance,
