Same answer as always when this comes up...
Download malwarebytes on another computer and put the downloaded file on a memory stick, start the infected computer in safe mode with networking (you'll need to connect the computer using a Ethernet cable, wireless will not work) once the computer is started in safe mode install malwarebytes from the memory stick, let it update and then run a full scan and remove all it finds.
