I can have three if I enable my tcpip on the firewire connection as well as the ethernet and wifi.
I have two internet connection icons on the taskbar. One is my regular internet connection and the other is something which came up a week ago. I have uploaded the screenshots here
I scanned my system with avast, asquared free, ewido, avg, spycatcher express and ad aware. My security setup includes Comodo firewall pro.
