How to Install a Computer Firewall

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. Data that is entering your computer should be challenged by a firewall. Dangerous attacks to your computer can negatively impact upon you but these can be avoided.

The type of firewall required for your computer should be ascertained since there are a wide variety available including those 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. You must check that it is turned on and working properly. BTW, I found a site about program development in Spanish: desarrollo programas. Your own software needs to be purchased if you do not have one of these later operating systems. The XP version doesn't get great reviews so you may still want to buy separate firewall software if you have Microsoft XP.
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. There are plenty of low cost versions available, even from the big name companies, with prices varying according to the sophistication of the software. A few things must be taken into consideration prior to the installation of your firewall. These programs can block certain functions that you need, so you must configure it to allow those, such as file and printing sharing. Settings can be configured during installation or at a later date using the documentation provided.

Firewalls tend to stop you from going to certain parts of the Internet as well. 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. 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.
