by Marco Maseko

It is important to know how and why you should install a firewall with the onslaught of computer hackers, scammers, and viruses that are prevalent around the Internet. Defense from malicious data harming your computer is provided by a firewall. Without one, your computer is prone to a dangerous attacks that can wipe out your data or steal personal information that can negatively impact you.

Determine the type of firewall required by your computer as there are a wide variety available. Chances are that your firewall is already set up and ready to be used if you have a computer that came installed with the Microsoft XP or Vista operating system. You must check that it is turned on and working properly.

You need to purchase your own software if you do not have one of these later operating systems. Owners of Microsoft XP may still want to purchase separate firewall software as the XP version doesn’t get great reviews.

The most popular products available are Norton, AVG and McAfee and you can either visit a store that sells computer software or download a firewall product through the Internet. Depending on the sophistication of the software, prices will vary but there are also plenty of low cost versions available, even from the big name companies.

You need to take a few things into consideration prior to installing your firewall. The program must not stop you using the functions that you need, such as file and printing sharing. This is normally done during installation but can also be done later by using the documentation provided to change the settings.

Parts of the Internet may be restricted by a firewall. It is important that you are familiar with how you connect because this can happen if you use a local area network or a router. It is difficult to access secured networks when you have installed a firewall. Before installing a firewall to a pc linked to a company network, you should liaise with the company’s IT department since they may give you a specific settings configuration so you are still able to connect to them.
