Windows Defender Security Center Pop UP Warning

I received a Windows defender security center warning that states my computer has been locked up due to my IP address being used without my knowledge. The audio message says to call 217-282-5011. I presume this is a scam. How do I get rid of this box that popped up and continues to repeat the issue continuously.

 

windows defender & security center services keep turning off


Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

If you are getting any error codes please list those, that will be helpful in helping you.

As torre suggested, might be a good idea to do a reset or even a reinstall.

Windows defender security center problem

When I try to start the windows defender security center the antimalware service executable starts up and uses up to 98% CPU. I have tried to change proxy restart defender and many suggested steps and also went to windows deffender online to do a scan
that way but no malware came up. The problem still persists. Does anyone know what to do in this situation? I just want my security to run properly but I cant even get to the menus.
