McAfee Firewall 4.0

The following are some frequently asked questions that you can briefly 
review:

McAfee Firewall protects your computer at the network level. It acts as a 
gatekeeper, checking every data packet going in or out of your PC. It allows 
only what you tell it to allow.

McAfee Firewall has been designed to be easy to use, while providing superior 
protection. Once you install and run it, it is configured to block known attacks 
and to ask you before allowing applications to communicate.

When you connect to the Internet, you share a network with millions of people 
from around the world. While the Internet is a wonderful and amazing 
accomplishment, it brings with it all the problems of being accessible to 
complete strangers.

While communicating via the Internet, you should take safety precautions to 
protect your computing environment. If you use IRC (Internet Relay Chat) 
programs, be suspicious of files total strangers send you. Programs that give 
others remote access to your computer, such as Back Orifice (BO), are 
frequently disseminated in this manner. It is a good practice to scan files 
received using anti-virus programs such as McAfee VirusScan before you 
open or view files and their attachments. 

When on the Internet, others can try to access your file shares. Therefore, you 
should check that they are only accessible to those you trust. Otherwise, 
untrusted parties can read and delete what is in your computer.

McAfee Firewall provides network level protection. Other important types of 
protection are:

n

Anti-virus programs for application-level protection.

n

Logon screens and screen saver passwords to prevent unauthorized 
access.

n

File encryption or encrypting file systems to keep information secret.

n

Boot-time passwords to stop someone else from starting your PC.

n

Physical access to the computer, e.g. stealing the hard drive.
