Guys I am not too worried about this.
The scanning is just very brief.
It could just be firefox loading all kinds of DLLs...
It's not like hours or days or anything like that.
So it's probably nothing... or just tiny little bit of spieing from FireFox.
If I catch more severe spying like windows 7 to windows 10 update/telemetry software/sneakyness I will let you know.
For now consider this very minor issue
Bye,
Skybuck.
