Windows Defender - Real Time Protection Won't Turn On
I've read many posts on this site already regarding Windows Defender - regrettably, here's another. Here is my situation: I have a laptop that originally had XP. I upgraded to the free Windows 10 version. I did have an anti virus installed. At one stage, I think I had some Trend version. I have completely uninstalled all AV versions that I'm aware of. I've even used the ESET AV Remover Tool - it returned zero results. I see nothing obvious in the "Apps & features" list. I've updated my registry to turn Windows Defender on (link), but to no avail. I have uninstalled Windows Security Essentials as per this link. For the first time, that turned on "Virus and spyware definitions", so I had a feeling that I was finally getting somewhere; however, WD continues to suggest that it's "handled by another AV program."
Where to from here please?
