Security Features
Guard Dog’s security features safeguard your Internet connection and protect
the files on your PC from prying eyes and destructive programs.
What Gatekeeper does
Gatekeeper lets you control what programs have access to your Internet
connection. Gatekeeper also can warn you about any of these potentially
harmful actions:
• Your browser is directed to a harmful site—one that has been known to
contain virus-infected files, Trojan horses, prank or destructive ActiveX
controls, or other security concerns.
• A program silently uses your modem to connect to another computer.
• A program starts up another program.
• A program sends out over the Internet a number that follows a common
credit card number pattern.
Responding to a Gatekeeper alert messages
Guard Dog 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.
Internet access alert message
Each time you start a program that attempts to use your Internet connection,
Guard Dog 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, Guard Dog 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 Guard Dog 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.
