Cannot Join HomeGroup on Network

[davi31]

All was well I think until the last AVAST Update.
I have the Avast Premium on some Win 7 machines and I share files between them.
Windows HomeGroup troubleshooter is pointing at the Avast Firewall as the problem.
What setting do I need to make in the Avast Firewall to allow HomeGroup in Win 7 to work again?

Set the Avast Firewall to private mode and reboot.

Set the Avast Firewall to private mode and reboot.

I had to mess with this when I first purchased the Premium stuff.

Finally gave up and deleted the HomeGroup I had.
Went into the Advanced Sharing setting and turned off the PASSWORD REQUIRED
Rebooted
Created a new HomeGroup
Got all the machines JOINED
Rebooted
All seems well again
I somehow think the Avast Firewall isn't?wasn't allowing the HomeGroup Password through.

Thanks for the feedback.
