Why You Need A Computer Firewall

By: Roncgeorge
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.

Since there are a wide variety of firewalls available, including those from major corporations such as Microsoft, you first need to determine what kind of firewall your PC requires. It is likely that your firewall will already be set up and ready to use if your computer came with the Microsoft XP or Vista operating system installed. However, it may not be turned on or working properly. If you have one of the earlier operating systems, you will need to purchase your own software. Even with Microsoft XP, you may still want to purchase separate firewall software since 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. Even from the leading companies, there are plenty of low cost versions available, with prices varying according to the sophistication of the software. Before your firewall is installed, a few things must be taken into account. The functions that you need, such as file and printing sharing, must not be blocked by the program. The documentation provided allows the settings to be configured during installation or at a later date.

Firewalls can limit access to certain parts of the Internet. Awareness of how you connect is important as if you use a local area network or a router, this could happen. Accessing secured networks when you have installed a firewall is difficult. 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.

Regardless of some of the technical issues when installing a stand alone firewall, which of course can be overcome easily if you read the documentation supplied by the software vendor. The benefits and security of your personal data and details is protected giving you more piece of mind against internet attacks and malicious programs.
