Many thanks, folks. It won't even load Safari. I'll take a look at the profile and delete that too. All this started when I loaded a Chinese ZTE MZ30 USB modem. It's subsequently also managed to destroy a 500gig external drive that I had attached when I had the modem attached. Drive is seen after an age but is inaccessible. Modem has been removed and drivers deleted. Bit late but let's see if we can repair the damage.
Low budget third world carppy rubbish...
