That looks like some form of malware may have infected your Mac. I suggest you get a copy of Malwarebytes, the free version should be good enough, and run it https://www.malwarebytes.com/mwb-download/

I suspect you have installed adware/malware:

>System Preferences>Profiles. found next to Accessibility (click into it and then remove all the suspicious things from the list.) May or may not be present if no profiles found.

Try running this trusted utility https://www.malwarebytes.com/mac/

also Verify you are not using SOCKS proxy:

>System Preferences>Networks>Advanced>Proxy uncheck the box

Adware/malware launch daemons can set SOCKS proxies without user participation.

(SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server.)

Third Party antivirus is not recommended, this typically causes nothing but added issues on your Mac.

Look for the official uninstaller.

Recognize and avoid phishing messages, phony support calls ...

Assuming you actually use CylancePROTECT then I suggest you follow their instructions to re-register your device from here https://home-support.cylance.com/hc/en-us/articles/360033608014-How-to-Re-register-Your-Device-With-Installation-Token
