Wonderful! Thanks for that pointer. It didn't work like a charm because "Reputation-based protection" was already turned on and so the "Windows Security -Actions Recommended" still remained.
Therefore, I proceeded with a more complicated fix, although at first, I was a bit hesitant to carry through with it. After much consideration & thought (and great trepidation) I did it anyway, even if it meant ending up with a bricked computer.
