Appreciate your help. Did the powerful scan with I0bit and removed the remnants but as stated, chrome seemed to have been usurped so I uninstalled it and tried to reinstall it from the google website. Unwanted products were installed and chrome wouldn't download - couldn't believe it. Now istartsurf has taken over! Managed to uninstall the other junk that came with it but neither Revo or I0bit list istartsurf as a program. Found the article on MalwareTips on "How to remove istartsurf" and gave it a go - no luck. I get deeper and deeper - maybe a dinosaur doomed to message sticks, snail mail and if I'm lucky the old copper wire phone. (Oops! Perhaps not! Even the phone is now through our NBN Co fixed wireless service.)
