Disabling Instant Messages:

To disable the ability for anyone to send netbios messages to your computer, you can deactivate the Messenger service. Its easy to reverse if you wish to later. Should you have any difficulties disabling the Messenger service please email us and we'll help you out. If you do not wish to disable File and Printer Sharing you may install a firewall and block the incoming traffic on port 135 UDP.
To deliver the message, our program uses a NetBios call built into the Windows API.

We are aware there are several imitators of our software that send on UDP port 137 and TCP 139, so you may want to block those also.

Disabling File & Printer Sharing on a Single Computer
If you are only using a single computer (not using a LAN), File & Printer Sharing should be disabled to reduce any potential security risks on your PC. Please use the following instructions to disable File & Printer Sharing:

On the desktop, double-click on My Computer.
Double-click on Control Panel.
Double-click on Network.
From the Configuration tab, click on the File & Print Sharing button.
Turn off file sharing and print sharing by clicking each box to remove the check marks.
Click on the OK button.
Select the TCP/IP protocol that is pointing to your Ethernet card or USB cable modem.
Click on the Properties button and click on the Bindings tab.
Click to uncheck the boxes next to "Client for Microsoft Networks" and "File and printer sharing for Microsoft Networks". NOTE: If there is more than one listing of TCP/IP, steps 7-9 should be repeated.

Enabling File & Printer Sharing on a Local Area Network
If you wish to share files on a Local Area Network (LAN), you should use File & Printer Sharing with NetBEUI. NetBEUI is a safe, non-routable protocol that can be used on a LAN to share files and printers.

Ensure that TCP/IP is not bound to File & Printer Sharing as shown in the previous section.
On the desktop, double-click on My Computer.
Double-click on Control Panel.
Double-click on Network.
Click on the Add button.
Select Protocol, then click the Add button.
Under Manufacturers, click on Microsoft and then double-click NetBEUI.
Click on the OK button to restart your computer.
