Using the Firewall

Using the Firewall
Essential Information
If the firewall encounters software on the Internet trying
to connect to your computer it will block it and pop-up
a message to tell you (Fig. 3). You must then choose to
keep blocking it or to unblock it. Check what the program
is. To begin with it’s likely to be your instant messaging
program or your e-mail software. These are fine. But if
it’s a program you don’t recognise, block it.
Action 1
Make sure your firewall is turned on. Open the Security
Centre and click on the Firewall button on the right to
switch it on. The Security Centre will then configure all
your settings automatically.
EXPERT TIP
Your fi rewall should work fi ne without the need to tweak
the settings. If you want to do this however, go to the
Security Centre and choose Manage security settings
for Windows Firewall. Select the Exceptions tab to
see the list of software to which you’ve already given
permission to access your computer. Untick any of the
software in the list if you wish to remove permission.
