I suspect you have installed adware/malware:

>System Preferences>Profiles click into it and then remove all the suspicious things from the list. (This Preference pane will not be present if no profiles found.)

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.)
