I'm unaware if this topic has been brought forth. If it has I do apologize. Comodo system information has shown under adapters; 5 Eset Perosnal Firewall Miniport(s) ("3" of which share the same information!) Adapter type: Ethernet 802.3 Description:Eset Personal Firewall Miniport MAC Address:------------ Which I have but don't recognize. Manufacturer:Eset Service name:Epfwndis System Name:blank-pc Of the remaining 2, MAC & Adapter type are blank the other is the MAC Address of my Laptop. Is it necessary to have 3 identical Mini port(s)? Why would one's adapter&MAC not be able to be identified? Can/Do I need to close the port(s) that I don't recognize?
