What is a firewall?

Greetings!

What is a firewall? How safe is your computer?

Have you ever wondered what the computer term "firewall" means? I went to Google for a definition I could understand: "A firewall is an extra layer of security built into computers which restricts access from the outside world. Firewalls protect against hackers and malicious intruders." Windows XP comes with a firewall as do many anti- virus programs. To see if your firewall in Windows XP is turned on follow these steps: LEFT click the Start button in the lower left corner of your screen. LEFT click Control Panel. DOUBLE LEFT click Windows Firewall. (LEFT click Security Center if you don't see Windows Firewall on your screen. Then LEFT click Windows Firewall.) If the button beside "ON" is not checked, LEFT click the button to turn it on. LEFT click OK. Close control panel. If your virus protection program also provides a Windows firewall you may get a message telling you that you don't need both and recommending that you turn off the Windows Firewall. Just follow the steps above to do so. Do you have friends or family who would find this tip helpful? Please click on the link below, Forward email to a friend!, and send it to them.
