Firewall and Shield

My Firewall is suddenly not working. I press the button to turn it on and nothing.
I go to the settings, everything is the same except now its telling me “Protection Status: Unknown”
So then I click Start and still nothing, it pops up with a message saying “Unable to start the Firewall! Shield unreachable.”
What the hell does that mean and how do I fix it?
I’m starting to get extremley irritated.

Have you tried avast repair?

I don’t see anything about a repair

Go to remove programs and click on uninstall avast, when you receive the popup screen choose repair and reboot when completed.

Thanks a ton! That fixed everything
