If you want to use your own computer as a WiFi access point one of the best tools for this is Maryfi.
With this application you will be able to share your Internet connection with as many people as you want, making it a very simple and totally secure process. After running Maryfi, whose interface will remain hidden in the Windows 7 taskbar, you will need to select the relevant network parameters you want to create, such as the WPA encryption-based password or the SSID name.
Finally, simply click on Start Hotspot and the program will create a virtual network available to anyone who knows the password you have defined in the program settings.
