The result of MiniToolBox is pasted below (I've also attached it herewith). I am desperately in need of good advice and guidance.

It has gotten to a point where I am starting to have a phobia about turning on my modem & router, and I don't even know if a VPN service would work at all because I do not know exactly where is his point of interference. I have to gather concrete information as proof to support my claim because I want to go to the authorities with this.

I am, therefore, pleading for urgent help on how to go about identifying and locating whatever has been added to my network to feed this sick person's twisted desires. One might be forgiven for thinking that it is my paranoia, but I am willing to bet my life that my network has been tampered with to include some kind of mirroring of my online activities to another machine, gadget or smartphone. When I clicked on it or tried to access it through Settings, it drops thus preventing me from accessing any information further: Today, my computer detected a connection called Local Area Connection and it has an ethernet symbol (whether the connection is really via an ethernet cable I am not so sure, it could be fake). Secondly, I have noticed a change in my home WiFi network lately and I am pretty certain that I am being spied on (that person is probably reading what I am typing right now) through my network.
