In the Uninstal programs section of control panel, put a tick in the box "Show updates". Wait for the list to fill and then look for Internet Explorer. When you uninstall IE11 it will roll back to IE10 and remove the browser hijacker. Run your Antivirus software and Malwarebytes. Turn off system restore to delete restore points. Turn system restore back on and create a restore point. Browser hijackers can hide in restore points and come back.
