With the increase in the number of computer scammers and hackers as well as viruses on the Internet, you need to consider the installation of a firewall. Between your computer and data that is entering it, this is your first line of defense. Malicious attacks targeting your computer can negatively impact upon you but these can be avoided.

The firewalls available vary widely and you must determine which type is suitable for your computer. 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. If you do not have one of these later operating systems, then you need to purchase your own software. Owners of Microsoft XP may still want to purchase separate firewall software as the XP version doesn’t get great reviews.

You can either visit a store that sells computer software or download a firewall product through the Internet - the most popular products available are Norton, AVG and McAfee. The price of software varies depending on how sophisticated it is but there are also plenty of low cost versions available, even from the big name companies. Once in hand and prior to installing your firewall, you need to take a few things into consideration. The program must be configured to permit the functions that you need, such as file and printing sharing. The information supplied gives you all the settings you need to be able to configure the software during installation or at a later date.

Access to certain parts of the Internet is limited by a firewall. If you use a local area network or a router this may happen, so you should be aware how you connect. Secured networks in particular are difficult to access when you have installed a firewall in place. Installing a firewall to a pc linked to a company network may require a specific settings configuration to allow you to connect to them and this can be provided by a company’s IT department.

Installing a computer firewall is not as hard as you think. All the documentation you need is bundled with your software package and there is usually a 24/7 support desk to assist you. To have a stand alone firewall is far better than having a internet intruder steal your valuable information or install some malicious file without your knowledge to track your every move while online.
