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.
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.
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. If you do not have one of these later operating systems, then you need to purchase your own software. Since the XP version doesn’t get great reviews, you may still want to purchase separate firewall software if you have Microsoft XP.
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.
Access to certain parts of the Internet is limited by a firewall. Awareness of how you connect is important as if you use a local area network or a router, this could happen. 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.
