While Windows 8 isn’t for me, many folks have gone the way of getting the new OS.
Because all OS’s are vulnerable (W8, too), and because of the recent fall from grace and decertification of MSE by AV-Test you should have security software installed.
While cruising the net, I found an article on The Windows Club which deals with the problem of W8 not detecting installed security software. This is not your fault. You can run sfc /scannow to your heart’s content, but it won’t help.
The problem is with wmiutils.dll . You have to re-register it.
How to:
- Press Win + X
- Click on “Command Prompt (Admin)
- regsvr32 /u WMIUTILS.DLL
- Reboot the System
- regsvr32 WMIUTILS.DLL
After rebooting, go to the Action Center. It will report your security software correctly.
If you’re having the same problem in Windows 7, there’s a hotfix:
