Hide My MAC Address has a straightforward interface that displays your network adapter and your computer's real Media Access Control (MAC) address. One click on the Hide button and the program assigns you a new MAC address. The advanced mode let us create our own MAC address and returned quick, accurate results. We tried using another program to retrieve our test PC's real MAC address and Hide My MAC efficiently protected our system.
Offered under a tight-fisted 3-day trial period, this simple program adds an effective layer of security to your system.
Anyone with the right tools can track your Internet activity if they know your MAC Address. Your MAC Address is continuously being sent over WiFi networks, even if they use secure WEP/WPA Encryption.
