McAfee Internet Security 5.0

McAfee Internet Security’s security features safeguard your Internet 
connection and protect the files on your PC from prying eyes and destructive 
programs.

Gatekeeper lets you control what programs on your PC can have access to 
your Internet connection. Gatekeeper can also warn you about any of these 
potentially harmful actions:

n

Your browser is directed to a harmful site—one that has been known to 
contain virus-infected files (e.g., Trojan horses, prank or destructive 
ActiveX controls, or other security concerns).

n

A program silently uses your modem to connect to another computer.

n

A program starts up another program. 

n

A program sends out over the Internet a number that follows a common 
credit card number pattern.

McAfee Internet Security can display five different Gatekeeper-related alert 
messages. If you are using the default settings suggested by the Interview, you 
will see the messages related to Internet access, harmful sites, programs 
starting another program, and programs sending out credit card-like 
numbers. 

Each time you start a program that attempts to use your Internet connection, 
McAfee Internet Security checks to see if that program is in the list of programs 
allowed to access the Internet. If the program is not in the list, McAfee Internet 
Security displays an alert message to tell you that the program is trying to 
connect to the Internet and asks you how to deal with the program. 

Because McAfee Internet Security displays an alert the first time you start an 
Internet program, you may want to start each of the Internet-connected 
programs you use regularly in order to get those alerts out of the way at one 
time.
