McAfee Firewall is a simple-to-operate security tool that dynamically 
manages your computing security behind the scenes.

During the installation process, the Configuration Assistant prompts you with 
basic questions to set up McAfee Firewall to do specific tasks – according to 
your needs (e.g. allow sharing of files or not).

McAfee Firewall filters traffic at the devices that your system uses - network 
cards and modems. This means that it can reject inbound traffic before that 
traffic can reach vital functions in your computer and waste valuable system 
resources. 

When McAfee Firewall is running, it monitors trusted and untrusted 
programs that communicate using the Internet. If a trusted application 
attempts to communicate, McAfee Firewall allows the program to function 
without restrictions. If an untrusted program attempts to communicate into or 
out of your computer, McAfee Firewall blocks the program’s attempt to 
communicate via the Internet.

Some network communications are needed to maintain network-based 
services. These are managed through user defined rules under the system 
settings of McAfee Firewall. The default system settings feature provides 
superior protection from hostile threats.

This manual provides the basic information you need to install, set up and get

get Help while working with the different windows and dialog boxes. You can

known issues, etc., about this product.
