Critical Steps to Protecting Your Computer on the
Internet

Spyware, viruses and worms... oh my!
If you are connected to the internet, you need to make sure you get
your computer set up properly if you want to avoid problems down the
road.
With all the viruses, spyware and other threats on the internet today,
no computer should be set up without the proper protection.
And that protection needs to be in place as soon after you hook up your
new machine as possible.
The following five steps will make your computer a much harder target
for threats. You still won't be completely immune to problems, but 99%
of the time the threat will pass you by, looking for the easy mark.
1. Running a Personal Firewall
A personal firewall is software that basically makes your computer
invisible to hackers, worms and other threats that can infect your
computer over the internet.
Setting up a firewall is the absolute first thing you should do if
you're going to connect to the internet. Without a firewall, your
computer could get infected in as little as one minute after
connecting.
If you have a brand new computer running Windows XP Service Pack 2,
there is a firewall built into Windows. It will already have been
turned on when you first set up your computer.
If you're running an older version of Windows, even an earlier version
of Windows XP, there is no firewall automatically set up for you. In
this case there are two possibilities:
- Your computer came pre-loaded with a firewall such as Norton Internet
Security or McAfee Internet Security
- You have no firewall installed and should download one ASAP.
If you don't have any personal firewall software installed, you should
do so right away. Zone Alarm is a very good firewall program that has a
version that you can download and install for free.

2. Turn on Windows Updates
Again, if you're running Windows XP Service Pack 2 this is already set
up, but otherwise you should turn on Windows Updates. Microsoft
releases updates for security problems and other bugs in Windows on a
regular basis.
These updates will keep your computer running better, and they often
fix security issues that could compromise your information or privacy.
If you are running Windows XP Service Pack 2, you can double-check that
automatic updates are turned on by clicking Start, then click Control
Panel, then double-click Security Center. The window that opens will
tell you if automatic updates are turned on, and lets you turn them on
if they're not.
To turn on automatic updates in earlier versions of Windows XP, click
on the Start menu, click Control Panel and then double-click on System.
On the "Automatic Updates" tab, click the option to "Automatically
download the updates and install them on the schedule I specify."
To turn them on in Windows 2000, click on Start, click Control Panel
and then double-click on Automatic Updates. Again, click the option to
"automatically download the updates and install them on the schedule I
specify."
Now when Microsoft releases updates, they will be downloaded for you
automatically and Windows will tell you when they are ready to be
installed.
3. Install & Update Antivirus Software
Most new computers come with antivirus software these days. You might
have Norton, McAfee, PC-Cillin or another brand. No matter what program
you have, you will need to update it when you get connected to the
internet.
It doesn't matter how new your computer is - there will be new viruses,
and new updates for the antivirus software, since it was loaded.
The exact process is different for each brand of antivirus program, but
most of them will have an icon in the bottom right corner of your
desktop, beside the time. The icon might be a picture of a shield
(McAfee), a stethoscope (Norton) or something else.
In most cases, if you point to the icon for your antivirus and click
the right mouse button, a menu will pop up with an update option. It
could be simply called update or could be something like Live Update or
Download Latest Updates. If you click on the update option (with the
left button this time) it will install the newest updates for you.
If you're not sure which icon is for your antivirus software, just
point to each one for a few seconds and a little title should pop up
telling you what it is.
4. Install Anti-Spyware Software
Spyware - and other things known as adware and malware - is becoming as
big a problem as viruses. Spyware programs can cause a lot of problems
with your computer, not to mention they can track your personal
information and you never know where it's being sent.
Some new computers might includes antispyware software, but most of
them don't yet. There are quite a few anti-spyware programs available,
some free and some not. The one I recommend is from Microsoft and is
one of the free ones.
One of the reasons I like it is because it always runs in the
background and will automatically catch a lot of spyware before it gets
on your computer.
Many of the other programs don't catch it until you run a scan. Not
only does this allow things to get on your computer, it also means you
have to actually remember to run a scan.

5. Set up a Free Email Account
This last item is not as critical as the first four, but I would highly
recommend you set up an email account with one of the free services
like Hotmail or Gmail.
Once you're on the internet, you'll find a lot of useful information
that you want that requires you to provide an email address. In some
cases, these people will end up sending you a bunch of spam.
If you use a free email account to sign up for anything that you don't
know for sure you can trust, it's not going to fill your main email
with a bunch of junk.
This goes for anything really, not just online information. If you're
entering a contest or signing up for anything offline and you don't
know where your information could end up being used, I would suggest
using your free email address.
If worse comes to worse, and your free email address gets inundated
with spam, you can always just set up a new one and let the old one
expire.
Some of the better free email services are www.hotmail.com,
www.gmail.com and www.yahoomail.com.
If you've had your computer for a while and never done any of these
things, you should still take these steps to get it set up properly. It
will definitely save you a lot of time - and possibly money - as you
use your system.
