McAfee Firewall
80 McAfee Internet Security 5.0
Program configuration
During your first attempt to start McAfee Firewall, the Configuration
Assistant asked you to identify programs that you want to allow to
communicate. At such time, McAfee Firewall created a default set of
communication rules for the programs (applications); designated as allowed
to communicate.
Based upon the type of program, for example, Internet browsers, e-mail, ftp,
IRC, and file sharing programs, McAfee Firewall identifies the type of
program and creates a default set of communication rules for each program in
your computer. That is, to either block, allow, or filter a program’s
communication attempts via the Internet.
Firewall Communication Alert Messages
A McAfee Firewall Communication Alert message displays if an
unrecognized program attempts to communicate. There are several scenarios
that could cause a program to be unrecognized.
n If you install a program that communicates via the Internet after
installing McAfee Firewall, the program’s first attempt to communicate
will cause an alert message to display.
n Although the Configuration Assistant performs a thorough analysis of
your computer’s programs that use the Internet to communicate, it may
not have been able to identify all of your computer’s programs that use
the Internet to communicate.
If an unrecognized program attempts to communicate, the resulting alert
message generally asks you to select one of the following options:
n No, deny at this time: Blocks the program’s current and all future
attempts to communicate. The active program is added to the trusted list
of programs with an allowed state of “blocked.”
n Yes, allow this time: The active attempt to communicate is allowed. The
program is not added to the trusted programs list.
n If you recognize the program and do not want to receive any future
alerts for this program, check the I recognize this program check box.
TIP
If you allow or block a program the first time you are prompted,
McAfee Firewall provides you with the flexibility to change this
setting and block or allow it to communicate at any time in the
future. As you exit McAfee Firewall, your settings are saved and
will be the same the next time it is run.
