Protecting Your PC on the Internet
Given the rise in numbers of computer hackers, scammers and viruses around the Internet, you should install a firewall. Between your computer and data that is entering it, this is your first line of defense. 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.
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 - this is especially true if you are using software from various Voip companies such as broadband telephony.

Since the XP version doesn’t get great reviews, you may still want to purchase 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. There are plenty of low cost versions available, even from the big name companies, with prices varying according to the sophistication of the software.

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.

Parts of the Internet may be restricted by a firewall. Awareness of how you connect is important as if you use a local area network or a router, this could happen. It is difficult to access secured networks when you have installed a firewall. If you work from home or connect to a company computer, you need to coordinate with the IT department in your company before installing a firewall since they may have specific instructions concerning how to configure its settings so you are still able to connect to them.
