I am getting, "not recognised as an internal or external command, operable programme or batch file,'.

I have since downloaded HitmanPro which removed the PUPOnesystemcare but not the PUPDNSUlocker.

Adwcleaner purports to remove both PUP's but it wasn't the case.

Was also advised to change the adaptor settings, in case DNS had changed them, but they were not changed.
