1Welcome to Internet Guard Dog
Using Internet Guard Dog
In the last fewyearsthe Internet has changedfrom acommunications network
that government entities and universities used almost exclusively, to an
information treasure house that people of all ages and occupations can now
access. With an Internet account, youcan send electronic mail (e-mail) around
the world in seconds, do research without leaving home, meet new friends in
an onlinechat room, or shop without getting out of your bathrobe. However,
with all these conveniences come a certain element of risk. When you use the
Internet, information istransmitted fromyourcomputer toother computers in
the Internet—information you may not want other people to have. And those
computers can also send files to your computer that may contain viruses.
While most of these files are harmless, some can invade your privacy or even
damage the data on your computer’s hard drive.
Figure 1-1. Internet Guard Dog Home screen
™
1
McAfee’s Internet Guard Dog addresses any of these potential risks with its
comprehensive features designed to protect your privacy and security when
surfing the Internet.
User’s Guide 1
Welcome to Internet Guard Dog™
With its new features, you can now also act as an Administrator and apply
customized protection settings not only for yourself, but for other users of
your computer and easily monitor potential risk they may encounter while
browsing the Internet.
How Internet Guard Dog works
Internet Guard Dog works via the following main features displayed in the
Home screen:
User Setup
As the Administrator, this feature allows you to setup protection settings for
other users of your computer. Y ou can add, edit and delete a user’s
profile—then setup individual privacy, security and Internet filtering options
that Internet Guard Dogwill apply w henever any of these users are browsing
the Web through your computer.
See the following for more information:
• “Customize User Setup Settings” on page 33.
• Chapter 4, “Privacy Features.”
• Chapter 5, “Security Features.”
VirusScan
Internet Guard Dog now uses the McAfee VirusScan to address virus-related
problems you may encounter through the Internet. This feature allows you to
set how to perform a virus scan operation on your computer; what to do if a
virus isfound; and how it should alert you once thevirus is detected. You can
also direct VirusScan to keep a recordof actions performedon yourcomputer.
With these mainfeatures of InternetGuard Dog, youarein controlat all times.
You decide what security and privacy features to use. If your concerns or
computing habits change, it is easy to change Internet Guard Dog protection
settings to meet your needs and those of others who use your computer
frequently. See “What is McAfee VirusScan?” on page 49.
Activity Logs
On the Internet Guard Dog Home screen, Activity Logs allow you to view a
list of all the interactions that you and other profiled users of your computer
had with Internet Guard Dog, including the date and time of the action. You
can print, save or clear this list. See “Viewing Activity Logs” on page 23.
2 Internet Guard Dog
Welcome to Internet Guard Dog™
Security Check
You can run a complete check of your computer for any privacy or security
problems via this feature. After Internet Guard Dog performs the check, it
displays any problem found, provides additional information about the
problem, and guides you through on how to solve the problem. See
“Performing a Security Check” on page 25.
Internet Guard Dog and your online connection
To use all Internet Guard Dog features, you must have an Internet connection
through a local network or a modem. Some networks have an Internet
connection that you can use by connecting to the network-either directly or
through dial-up networking. If you don’t connect through a network, your
computer must have a modem installed.
You can establish anInternet connectionthrough anInternet Service Provider
(ISP) such as Earthlink. An ISP acts as a middleman between you and the
Internet. Your computer connects (using your modem) to the ISP’s equipment,
which in turn connects to the Internet. You may also be connected to the
Internet through an online service such as America Online or Compuserve.
In addition, you must also have a browser. A browser is software, such as
Netscape Navigator or Microsoft Internet Explorer (it must be a version
designed for Windows 95 or Windows 98), that allows you to view text and
graphics and download files from Web sites.
Internet Guard Dog features
This section brieflydescribes other featuresof Internet GuardDog that protect
you from the most common Internet threats. If you want more background
information on Internet privacy, security, and virus issues, see “Internet
Security and Privacy” on page 55.
NOTE: Only the designated Admi nistrator or Self-Administrator can
have access to these features which allow them to customize protection
settings for themselves and in the case of the Administrator, protection
forotherprofiledusersofthesamecomputer.
User’s Guide 3
Welcome to Internet Guard Dog™
Protection from privacy threats
• Identity Protector monitors your Internet connection and warns you
before private information is sent to an unsecure Internet site. It stops
programs and other people that use your computer (like your kids) from
sendingyour name and credit cardnumbers overthe Internetwithout your
approval.
• Cookie Blocker prevents Web sites from storing cookies on your hard
drive. Third-party Web sites use cookies to track your Web browsing
habits. You can choose your level of interaction with Cookie Blocker. (For
more information, see “What are cookies and how are they used?” on
page 65.)
• Web Trail Cleaner cleans yourWeb browsing trailssuch as cachedfiles; list
ofURLs (Uniform ResourceLocator,also known as Webaddress)visited; and
history files—when you close your browser. This feature prevents other
users of your computer to track your online movements by viewing the
files and URL addresses l eft over from your Internet browsing.
• Search Filterprevents search information that you request at one Web site
from being passed along to the next site you visit. Without Search Filter,
your browser can transfer your search request information from one Web
site to another without your knowledge.
Protection from security threats
• Gatekeeper allows you to control the programs that have access to your
Internet connection. Programs on your PC can be programmed to access to
the Internet without your consent.
• File Guardian protects files that contain your sensitive data from being
opened, renamed, copied, moved, or deleted. Programs, such as ActiveX
and Java programs, can scan your PC for personal information or delete
files without your permission.
File Guardian also limits access to protected files either to programs you
specify or through file encryption. It can limitthe programs that can access
your tax, on-line banking, or personal accounting data files.
• Password Manager stores your Web site login names and passwords for
protected Web sitesin one securelocation. When you are visitinga site that
requires this information, drag it from Browser Buddy to the form
displayed in your browser. No more storing your login names and
passwords in an unsecure location, such as post-it notes on your monitor
or in a text file on your Windows desktop.
4 Internet Guard Dog
Protection from virus threats
Using the McAfee VirusScan, the following features are available:
• Scan to start the default virus scan task immediately, or config ure a virus
scan task that suits your needs.
• Scheduler to launch the McAfee VirusScan Scheduler. This utility enables
you to configure and run unattended virus scan operations.
• Virus info to display virus information via the McAfee Web site.
What’s new in Internet Guard Dog
Internet Guard Dog version 3.0 includes these new features.
• Inclusion of McAfee VirusScan
McAfee VirusScan is now included in Internet Guard Dog. Select from
availableoptions to customized how you want itto protectyour computer.
• Multi-user Logon and user settings
Internet Guard Dog now allows multiple users to have different
protections settings. The main user can also act as an Administrator
customizing settings for other users of the same computer.
Welcome to Internet Guard Dog™
• Internet Filtering options
After an Administrator has added profiles of other users of the computer,
Internet Filtering optionscan be usedbased ondefault URL sites,word list,
rating systems, and Internet access time. Administrator can also enter
additional lists or sites if desired.
• Activity Logs
An Administrator can view a list of activity, maintenance and violation
logs at the single click of a button. This list contains information such as
duration of computer use or any protection setting violation that a profiled
user may have committed (e.g., attem pting to pass credit card number).
Administrator also has the option to clean, print or save this list.
• Improved online Help interface
The online Help is now displayed via a tri-pane Explorer View Help
window. While viewing a topic within the Help file, the user can now also
view the table of contents as well as access the index and full-text search
options simultaneously while the topic is displayed on the right-hand side
of the window.
User’s Guide 5
Welcome to Internet Guard Dog™

viewed or changed. It also prevents other users of your computer from
sending out information that you specify as private.

Protects individual files even when encrypted.
• Improved cookie management

without your OK.

being read—until you decode them.

What information does Internet Guard Dog ask me to enter?
The Internet Guard Dog interview asks you to enter the personal andfinancial
information that you want to protect. All the information you enter into
Internet Guard Dog is stored in encrypted form on your hard disk— it is never
sent to McAfee Software.
You may want to gather your personal information before you start the
interview. During the interview, Internet Guard Dog allows you to enter:
• A password that you can use to protect your Internet Guard Dog
information.
• Personal and financial information that you want to protect from being
sent out over the Internet without your knowledge:
•Name
• Address
• Social Security number
• Telephone number
• E-mail address
• Other financial numbers such as bank account, brokerage account,
credit card, phone card, and so on.
• Any Web site login names and passwords that you want to store in
Password Manager.
• Information about other users of your computer. If you are the
Administrator, you can create user profiles and set protection settings that
Internet Guard will use whenever the user is browsing the Internet via
your computer. See “How Internet Guard Dog Administrator works” on
page 17.
For optimal protection by Identity Protector, include all dashes (such as Social
Security number, bank account numbers, brokerage accounts, and ATM
cards). For example, if you enter 123-45-6789 as your social security number,
Guard Dog will recognize the number with or without the dashes. If you enter
123456789, Guard Dog won’t alert you if the number is sent out with dashes
(123-45-6789). Credit cards do not need dashes because you type the numbers
into separate boxes.

How Internet Guard Dog Administrator works

certaintypes of informationthat you donot want your children toaccesswhen
browsing the Internet.
Creating an Internet Guard Dog Administrator account can only be done in
the Interview feature of Internet Guard Dog. And only the designated
Administrator can access and change information and protection settings of
the computer.
After this setup is complete, the Administrator can add other users and set the
levels of security and protection for each user profile.

how to set an Administrator account.
