I'm connected to three networks at once, what does thet mean?

Hello!
I have a short question, why the firewall shows that I’am connected to three networks at once? I have Avast Premier, I’am connected through ethernet cable.
It looks like this: https://drive.google.com/open?id=1t7CaYdDbLdffT4ebiBaeIeCF276hnoNi

Thanks!

Please attach your screenshot, some of us don’t follow external links. :wink:

Since the screenshot is not in English, it’s difficult to understand. I would assume they are virtual network adapters which were installed with VPNs and Virtualization software. It’s nothing to worry about.
