Do
I Need Both a Firewall and an Anti-Virus Program?
By Dennis Brooks
The
answer to that question is an emphatic YES.
They are
both security devices that protect your computer while you
are on the internet, but they do different jobs.
Firewalls
A firewall
protects your computer from invasion by blocking the ports
that allow access to your computer, but allows traffic to
pass through from it.
There
are basically 2 types of firewall, software and hardware.
A software firewall is a program you run on your computer
that blocks all the ports for you, it then checks the programs
on your computer to see which ports it needs to open to allow
these programs to run.
A hardware
firewall is a separate device that is installed between your
computer and your modem. This then physically stops anything
getting to your computer from outside unless you have allowed
it, normally it has certain common ports open to allow access
that is needed.
If you are using a router to connect to the internet, most
of the modern ones have firewalls built into them, so you
don't need an extra device.
Anti-Virus
Programs
Anti Virus
software protects your computer by stopping the activity of
viruses or malware programs when they have got into it, you
may well have allowed them onto your computer by opening an
infected email or visiting a website that has asked you to
download an infected program.
Of course
you wouldn't deliberately allow something into your computer
so they are usually disguised as something you do want.
Anti virus
software is installed on your computer and is constantly checking
the system for unexpected activity, if it sees some it checks
it out, if it is suspicious it will warn you and you will
get the option to delete it or put it into quarantine.
This is
just a very basic overview but as I said at the beginning,
to make sure your computer is as safe as you can make it you
need both a firewall and anti-virus software installed on
your system.
Dennis
has been working with computers and network marketing for
the last 3 years and wants to pass on some of the information
he has learnt over that time, to help you to market better.
His website is http://dennisb.ws
there is a lot of information there to help newcomers to internet
marketing.
It is still under development so there is frequently new information
added.
Another
aspect he is passionate about is computer security, too many
people do not take the protection of their computers seriously
until they are attacked and possibly their data destroyed,
or they find their information is being used for illegitimate
purposes
If you
want to learn more about marketing efficiently one of the
best resources available is The
Renegade University. You can join for free to get started,
then if you want to upgrade you can.
This was
originally created for the MLM industry but the methods are
applicable for all forms of network marketing.
