I think it’s Bright VPN. Remeber when you Installed it, it explain that it uses your connection? Going to their web site, it tells you on the front page “You allow Bright Data to use your Internet connection. This pays for your premium VPN subscription.”

I have the same problem. I noticed it few days ago. Maybe its a bug in new Windows update.
