I don’t get it. What’s all the fuss?
I just set up my virus software, it
does it’s thing and I don’t have
any problems. So why do I need
more than a virus program?

There is more to protecting your
computer than setting up a virus
program. Go to Microsoft.com
and you will see this …

The Big Picture
We equate Internet security to Medieval
days. There is no Internet army to stop an
attack on you. You are on your own. To
protect yourself you must build a castle and
a really big moat around it.

DSL or Cable Modem
• This is your Broadband, ISP, Cable provider
or Satellite dish hookup
• Essentially, this is your high speed
bandwidth connectivity to the internet.
• If you have dial-up (phone line), then you
will not likely have a router or physical
firewall.
• You will depend on software protection.

12
Router
• Splits up a single user on a DSL/Cable
modem to into multiple users. Often serves
as a firewall device.
• A commercial router, like a CISCO,
provides many more capabilities.

13
Firewall
• A firewall has several uses. Primarily it is
used to stop intrusion. It can be a software
program on your pc or it can be a hardware
device.
• Hardware firewalls protect more effectively
than most of the low end software packages.

14
Software Firewalls
• Norton internet security (virus & firewall)
(popular & suitable)
• McAfee (good web site)
• Trendmicro (great site too)
• BlackIce (technical, but also good)
• ZoneAlarm Pro4, or free (ZAP4: my
personal choice for most protection and
detailed control).

What’s the difference between a Worm and a Virus?
A worm is a program that can run independently and can propagate a fully
working version of itself to other machines. It is derived from the word
tapeworm, a parasitic organism that lives inside a host and uses its
resources to maintain itself.
A virus is a piece of code that adds itself to other programs, including
operating systems. It cannot run independently—it requires that its
‘‘host’’ program be run to activate it. As such, it has an analog to
biological viruses — those viruses are not considered alive in the usual
sense; instead, they invade host cells and corrupt them, causing them to
produce new viruses.
