Protecting Your PC on the Internet
By Wayne Hamilton | March 15, 2009
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. It stops your computer being prone to dangerous attacks that can negatively impact upon you.
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 though you might have to tweak it if you are using broadband telephony with software offered by various Voip companiesor other addons to your PC. Check that it is turned on and working properly. Purchase your own software if you do not have one of these newer operating systems. Owners of Microsoft XP may still want to purchase separate firewall software as 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. 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.
The functions that you need, such as file and printing sharing, must not be blocked by the program. Settings can be configured during installation or at a later date using the documentation provided.
Certain parts of the Internet can be blocked by a firewall. You should be aware how you connect as this may happen if you use a local area network or a router. When you have installed a firewall in place, secured networks in particular are difficult to access. 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.
