windows 10 update and firewall won't come on

[REDACTED]

I've restarted my computer numerous times does not help bring back firewall thru avast.  The windows firewall seems to be working as well as all of the updates for avast are current, but I still get the warning icon on avast icon in my task bar that shows my firewall is not on and I can' turn it on.


Any help, suggestions, support would be appreciated.
