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.

13

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.

14

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.

15

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).

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.
