Removed AntiVirus software still shows as installed
Windows identifies old security software as still installed
1) Check Registry for residual keys
his could happen because even after uninstalling the security software, it has left some remnants in your registry. Use its own standalone uninstallers to uninstall it completely. Else try a freeware registry cleaner like CCleaner and see if it helps. Additionally, open the Windows Registry, search for its keys and delete them. Let’s say the product is named ABCAV product of XYZCO company, then do a Find / Find Next for both ABCAV and XYZCO, and delete such keys found. I am assuming that you do not have any other software of XYZCO company installed.
2) Re-start the WMI Repository
If it doesn’t help, it is quite possible that the problem may be resolved by re-starting the WMI Repository. To do so, in start search > Type CMD in search > Hit enter. From the results, right-click Command Prompt and select ‘Run as Administrator’. Type the following command: If you get a message WMI repository is consistent, run the following command one after the other and hit Enter: If you get a message WMI repository is not consistent, run the following command: This will perform a consistency check on the WMI repository and resolve the issue. Restart your machine. After restarting your computer, if you receive the following message: winmgmt /salvagerepository is failed, ignore this message, and again run: Reboot.
3) Check GUID
If this doesn’t help, KB980867 suggests that you do the following. Open an elevated command prompt, wbemtest, and then press Enter. In the Windows Management Instrumentation Tester dialog box, click Connect.
As appropriate for your version of the operating system, type the following in the Namespace text box: For Windows Vista: For Windows Vista SP1, Windows Vista SP2, Windows 7, Windows 8, Windows 10 and Windows 11: Click Connect. Click Enum Classes.
Leave the Superclass name text box blank, and then click OK. Double-click AntispywareProduct, AntiVirusProduct, or Firewall Product, as appropriate for your version of the operating system.
Click Instances. For each GUID that is listed, follow these steps:
