Apparently I’m not making myself sufficiently clear: the popup warning window was completely nonresponsive: it appeared as a visible object but could not be interacted with. No buttons were functional. No selectable objects could be selected. Nothing could be done with or about it in any way, outside of moving it across the screen (a Windows function, not an avast! one). So there’s no need to ask for any more information about it, because there is none to be had. The only other information I can provide is about the Windows installation, hardware, other scan logs as noted, and the like. This glitch, which I still think it was, consisted of whatever can be gleaned from the screencap posted previously and nothing more.
