Avast firewall turned off.

A pop-up happened just before by avast saying avast firewall turned off.

Is the firewall included in the free version of avast? I noticed then I clicked the firewall option in Tools I get taken to 2 priced plans.

I’ve never seen this firewall pop up before, so just clarifying, is the firewall part of the free version of avast?

If it is, then how do I turn it back on?

I’m using Win10 Pro.

Nope.

Ok, thanks for the reply.

You’re welcome.

There’s also nothing wrong with the firewall already built into Windows 10.
The free version of Avast and the firewall built into Windows 10 work very well together.
It’s the combination I use. ")
