A firewall is a software program or piece of equipment that can track hackers, viruses and worms that reach your computer over the Internet.
However, even if a firewall is essential, you also need antivirus software and antispyware software.
Here are some tips to remember to secure your computer with firewall software:
- Windows XP SP2 or higher and Windows Vista have a built-in firewall and enabled by default.
- If you use a computer at home, the most effective and important first step you can take to help protect your computer is turn on a firewall.
- If you have more than one computer connected at home, or if you have a small office network, it is important to protect all computers. You must have a hardware firewall (a router) to protect your network, but you must also use a software firewall on each computer to help prevent the spread of a virus in your network if one computer is infected.
