On startup, the background on my monitor is BLACK and there is a large ad in the middle of my screen! This is the most recent of a list of harassments with NO
Explanation of any kind WHY I've been targeted! One day when I started my
Computer, there in the middle of the screen was my name in large black capital
Letters. What gives Google the right to persecute ANYONE?

How do you know the agents behind this act ?

Sounds like you have some malware issues, that can be easily solved with a complete rebuild.

Doubt Google. Do a scan for malware.

I agree, doubt it was Google... Facebook I wouldn't put it past those bunch of fascists, but I think you have malware on your machine.
