| Internet firewalls are an important
part of keeping your computer protected from worms and viruses.
If kept frequently updated, and internet firewall will offer you
some measure of protection from destructive forces that can cause
permanent damage to your computer. Without a firewall, your computer
could be flooded with worms, viruses, spyware, and several other
detrimental elements that could potentially steal your personal
information and/or cause your hard drive to crash. Most internet
firewalls can be updated and adapted to intercept new bugs, but
you will need to check for updates often.
The more layers in your firewall, the better protected you
will be. A firewall resembles a system of tunnels that causes
spam and viruses to travel through a maze, which makes it quite
difficult for the virus to reach its target - your computer
files. As worms and viruses become more complex, the harder
your firewall will have to work to protect your computer efficiently.
Each time you operate a computer that is connected to another
computer, you run the risk of allowing destructive information
to pass through. Surfing the internet without a firewall is
much like entering battle with no body armor. You run the risk
of infecting your personal files with a virus or worm that could
prove to be quite difficult to get rid of. You must make sure
that your firewall protects incoming as well as outgoing information.
There are different kinds of firewalls. Some are free, some
charge a small monthly fee, and some can be purchased outright
and updated on the manufacturer's web site. There are several
well-known brands of firewall software than can be installed
on your computer or network that will give you a reasonable
measure of protection. Make sure you always have the latest
version of whatever type of firewall you choose. There is no
foolproof way to protect your computer from harmful worms and
viruses, but a firewall is the best place to start.
