I am running the BitDefender Firewall with "Allow Known Programs" - the setting it was installed with. In the "Whitelist" of "Trusted Applications" I see names that are unknown to me. For example, "123 Hidden Sender"; "Alchohol 120" ""Alchohol 120%"; "Any FLV Player";..........."Rufus" etc. Can I assume that this long list is valid - there does not seem to be any way for me to remove names that are unknown to me.
