Something is seriously wrong with both your systems, and it�s impossible to guess exactly what it might be, or how it could be happening on both your systems. I�ve never seen anything comparable on macOS or Windows. This is only a guess, but perhaps you changed some default security settings? There is a lot of dreadful but plausible-sounding advice out there about security and privacy, sometimes offered through mere incompetence, but sometimes, apparently, through mischievousness. I�ve seen advice about protecting systems from intrusions from Apple or Microsoft by making changes that in fact increase risk and cause endless inconvenience. If you changed security settings, and you don�t remember what they are so that you can try to reverse them, then you may need to back up all your documents, wipe your disks, and start over with fresh installations on both machines, this time not changing any settings that affect security. Even if you didn�t make any changes, the only solution may be to do the same thing, because something is drastically wrong with both your setups.
