With the onslaught of computer hackers, scammers, and viruses that are prevalent around the Internet, it is important to know how and why you should install a firewall. This is your first line of defense between your computer and data that is entering it. Dangerous attacks to your computer can negatively impact upon you but these can be avoided.

You first need to determine what kind of firewall you need for your computer as there are many available including some from major corporations such as Microsoft. A firewall is likely to be set up and ready to use if the computer came installed with the Microsoft XP or Vista operating system. However, you do need to make sure that it is turned on and working properly. Purchase your own software if you do not have one of these newer operating systems. Even with Microsoft XP, you may still want to purchase separate firewall software since the XP version doesn't get great reviews.

The many products available, include Norton, AVG, and McAfee and can be purchased in store or downloaded from the internet. 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. You need to take a few things into consideration prior to installing your firewall. The program must be configured to permit 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.

Access to certain parts of the Internet is limited 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. A pc linked to a company network may require a specific settings configuration to allow you to connect a firewall to them and the company's IT department should be able to advise you with this.
