I have this same problem, any idea what the miracle solution was that allowed you to scan? This problem started for me when AVcure.exe installed its self and started making havoc. Ive since deleted avcure, msa.exe, msb.exe, d.exe, f.exe manually. But still get the problem that youve been working one while trying to open Malwearbites, Kasprskey, S&D. I've dropped the maba.exe into the fr33 program which fixes it long enough for me to open it, but after i start a scan it closes then the permissions problem happens again. I've tried to recreate lumas fix with a no go. Any further advice?
