Running a boot scan now with Avast. Actually, the tech went on to other customers and had me time it.

@Keith, mine is a private internet connection, not the facility. I have absolutely no problem with YT on my desktop.

Tech suspects Freecorder. What do you use for recording audio from the web? I just neutered Freecorder. At one time, Firefox recommended it. They don't any longer. To much invasive garbage attempts to bloat your system.
