Left click on My Computer and in the menu bar across the top under Edit click on Find.
In the Find box type in winmx and hit enter.
Right click and delete any reference to winmx that may come up. An easy way to find the next reference is to hit F3 on your keyboard to Find Next after you find the first reference.

Once you have uninstalled any P2P software that was detected by the security scan and taken any additional steps needed to remove them please rescan your computer to continue the registration process.

Find a Game Console's MAC Address

Nintendo DS

To obtain the MAC Address from a Nintendo DS, you must first insert a Nintendo Wi-Fi Connection compatible game and access the WFC Setup Utility.

After accessing the utility, tap "Options," then "System Information."

The MAC Address and Nintendo WFC ID will be listed on the screen. Unless the game player has successfully connected with Nintendo Wi-Fi Connection, the WFC ID will be blank.
