I might have installed this a long time ago and not remember it, but I definitely did not install this on the 20th of last month. Nobody uses this computer but me, and nobody has my password. I have accidentally left the computer logged in, but I have it set to ask for Admin privileges when installing new apps.
I did have Unifi tech do a remote on my network last month, so it could be that. I watched everything he did and was on the phone with him.
