Install a Firewall

How to install a new firewall:

If you are not certain you have a firewall, and that also it is enabled, go to the "firewall emergency" page before you do anything else.

1. Physically disconnect from the Internet
2. Turn off the Windows Firewall
3. Install the new firewall
4. Reconnect and quickly test the new firewall
5. Disconnect, and take corrective action if the test fails

If you are installing Service Pack 2 for Windows, you may want to keep an existing firewall instead of turning the new Windows Firewall on. Read through the tracks below before you make up your mind.

In any case, be sure you do not have more than one firewall activated at the same time. The two may even defeat each other. [Instructions for deactivating Windows Firewall]
