If you are using ForScore on a single machine, firewalls are not an issue.

If you are running on computers networked together and any of the machines has a firewall, you will need to configure the firewall to enable the client machines to communicate with the server or master computer on which the database resides.

 

ForScore itself does not engage in any network activity that's likely to make a firewall unhappy.

FSCheckUpdate.exe is invoked when you use the Help menu option to check the Beach Bunny Software website for possible updates.
