Wireless Networks Unavailable After System Recovery?

I did a System Recovery after my computer had the virus that redirected me to a pop ups and different websites every time. After System Recovery I no longer have internet connection on the computer I used. All the other devices and computer can access my router but not the computer that I've used System Recovery on. I looked at Device Manager and all of my Networking Devices are working properly. I even looked at Wireless Zero Configuration and the Startup type is Automatic and the Service Status is Started.I go into Network Connections and my USB Adapter has an red X on it. I right clicked properties and looked at wireless networks and the preferred networks is grayed out[CODE]
