The best way to "unblock" the program is to go into the firewall
configuration and create an exception for the particular program. The
following KB has more information and good list of steps to accomplish this:

Enable programs by using Windows Firewall
If you do not click Unblock the program in the Security Alert dialog box,
the program continues to be blocked. To enable a program by using Windows
Firewall, follow these steps: 1. Click Start, click Run, type wscui.cpl in
the Open box, and then click OK.
2. Click Windows Firewall.
3. In the Windows Firewall dialog box, click the Exceptions tab, and then
click Add Program.
4. In the Add a Program dialog box, either select the program from the list
that appears, or click Browse to locate your program.
If you cannot locate your program, see the next section.
5. After you select your program, click OK.
6. On the Exceptions tab, make sure that the check box next to your program
is selected, and then click OK.
Note If you later decide that you do not want the program to be an
exception, clear this check box.
Adding a program to the list of exceptions has the following advantages:
• You do not have to know a specific port number. (By contrast, when you
want to open a port, you have to know the number of the port that is used
by the program. This is described later.)
• The port that is used by the program that is on the list of exceptions
will be open only when the program is waiting to receive a connection.
