When I run the Firmware update tool, the "Program failed to run" message appears on my PC screen.

The scanned data is attached to an E-mail application which I do not use regularly, or the error message indicating no default E-mail application is registered on my computer (CC4-121-xxxxxxxx) when trying to scan a document directly into my E-mail application using ControlCenter4 or the SCAN key on my Brother machine.

When I install the drivers, Norton AntiVirus displays a Security Alert that a medium risk application "xxxxx.exe is attempting to connect to a DNS server".

I am using Safari in Mac OS X. When I created a CSR or a Self-signed Certificate using the IP address to configure the "Common Name" and I try to access the Print Server using Safari with SSL communication, Safari issues an alert.
