virbr0 -- just discovered and wondering if it is causing Skype problems

Asked by Michael Lynch

While trying to have a Skype video call tonight, our call kept getting cut off or otherwise not connecting. While trying to figure out if there was a problem with my WiFi and internet connections, I suddenly discovered that "virbr0" showed up. I have never seen this before.
I followed some instructions at http://askubuntu.com/questions/246343/what-is-the-virbr0-interface-used-for for trying to remove it, but the terminal says "bridge virbr0 is still up; can't delete it" (it will not allow me to turn it off, either).
Numerous questions related to this:
1. What is virbr0?
2. How did it end up on my machine? (Dell Inspiron Desktop -- running Ubuntu 15.10)
3. Would it affect my laptop computer's ability to connect to WiFi via the router?
4. How can I shut it off?
5. Can I delete it, and if so, how?
