The router and ICF are about the same. The both stop unsolicted inbound
traffic to the machine, but they provide no outbound protection.

MaAfee should be providing application control and stopping a program
from accessing the Internet.

If you have gone to the Ethernet NIC's Properties on the Advanced Tab and
enable ICF, then it's enable on the NIC and it's active.

Yes the router is better than the ICF in someways, mainly because it's a
stand alone device that sits in front of the machine and the machines
behind it with the O/S and possible FW on them don't have to deal with
the scans/attacks.

Along with providing the ability to stop an outbound connection by an
application trying to connect to the Internet -- application control, it
provides inbound and possible outbound port control behind the router
