Why is there a new account called "AvastSoftwareUpdater"?

Today when I turned on my computer it said there were two accounts and Avast Software Updater was one, and it is pw protected. What is this and why did Avast create it? I certainly didn’t do it, I’m freaked out right now. I tried to go into users to see where it was but it isn’t showing up.

What is going on with this?

Reboot. Is it still there…??

Okay I restarted and I don’t see it now. Just a temporary glitch?

Yep.
