Excellent. Thank you Marcos. I have used the uninstaller tools which of course only listed an option to purge eset security leftovers which I selected and completed no issues there. Then removed ZA and turned windows firewall on just in case prior to reinstalling ESET which completed the process successfully on its own, self updated and it is all good.
One last question before this topic is closed. When using the uninstaller, eset listed my OS as Win 10 pro x64AMD 😐 I have Intel 11 x64 processor. I think win 10 pro usb installation was automatic I didn't select which architecture to apply for the OS installation. Have I possibly done something wrong during OS install? any thoughts? Thanks again.
