Steps To Protect Your Computer:

1. What is a firewall?
A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet.
NOTE: A firewall is essential, but you also need antivirus software and antispyware software.
•If you use a computer at home, the most effective and important first step you can take to help protect your computer is to turn on a firewall.
•If you have more than one computer connected in the home, or if you have a small-office network, it is important to protect every computer. You should have a hardware firewall (such as a router) to protect your network, but you should also use a software firewall on each computer to help prevent the spread of a virus in your network if one of the computers becomes infected.
(If your computer is part of a business, school, or other organizational network, you should follow the policy established by the network administrator. In some cases, network administrators may configure all computers on the network so that you cannot turn on the firewall while your computer is connected to the network. In those cases, you should ask your network administrator for guidance on whether you need a firewall on your computer.)

How to choose a firewall?
Three basic types of firewalls are available for you to choose from:
•Software firewalls
•Hardware routers
•Wireless routers
To determine which type of firewall is best for you, answer these questions and record your answers:
1.How many computers will use the firewall?
2.What operating system do you use? (This might be a version of Microsoft Windows, Apple Macintosh, or Linux.)
That's it. You are now ready to think about what type of firewall you want to use. There are several options, each with its own pros and cons.

Use the right firewall for your version of Windows?
A firewall helps protect your computer from hackers who might try to delete information, crash your computer, or even steal your passwords or credit card numbers. Depending on which operating system you have on your computer, you might already have a firewall and it might already be turned on for you. A firewall is included in most Windows operating systems. To turn on or check your firewall settings, click the link that corresponds to the operating system you use.
