Personal Computer Firewall Issues

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. Defense from malicious data harming your computer is provided by a firewall. With one, you can avoid dangerous attacks that can wipe out your data or steal personal information.

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 computer that came installed with the Microsoft XP or Vista operating system is likely to have a firewall already set up and ready to use.
However, it may not be turned on or working properly. If you do not have one of these later operating systems, then you need to purchase your own software. The XP version doesn't get great reviews so you may still want to buy separate firewall software if you have Microsoft XP.

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.
