I had a similar issue over the past few days. I updated to Windows 10 and have found they are leaving of back doors with mini VPN Virtual Private Network. Ports are opened up. I thought I had a virus. Apparently the new Windows update wants to hold you hand while you're on the internet. What I found disturbing is how many Windows listening devices were listed on my network. The only way I found out what was going through my firewall was with my ESET smart security tools under network scan. There is a little tension between the two firewalls (integrated and installed), plus ESET has a scanner tool that will look for antivirus conflicts. I ended up blocking everything until I could figure out who was who. I hope this has helped you as it has helped me come to grasp the new age of software. These days it says just click here to install, and your privacy goes out the window.
