Firewall won't start in AIS 2014

Avast Free Antivirus / Premium Security

When I try to start the firewall I just get the message “unable to start firewall” I’ve tried switching from public to private, I’ve tried rebooting but it’s made no difference. Any suggestions. I’m using Windows 7.

TIA

I’m glade this was posted, I was trying everything except Repair. Worked Great.
