Information:
This will show you how to add or remove a Windows Firewall program exception for each type of network location (ex: Private or Public) that you use in Windows 7. Some of these steps may or may not work on Windows XP.
Warning:
When you add a program to the list of allowed programs in a firewall you allow a particular program to send information to or from your computer through the firewall. Allowing a program to communicate through a firewall (sometimes called unblocking) is like opening a tiny door in the firewall.
Each time you allow a program to communicate through a firewall, your computer becomes a bit less secure. The more allowed programs your firewall has, the more opportunities there are for hackers or malicious software to use one of those openings to spread a worm, access your files, or use your computer to spread malicious software to others.
To help decrease your security risk:
Only allow a program when you really need to, and remove programs from the list of allowed programs that you no longer need.
Never allow a program that you do not recognize to communicate through the firewall.
Here's How:
1. Open the Control Panel (All Items View).
