Windows Network Diagnostics - Proxy Settings Not Automatically Detected

I have recently run a virus scanner from mcaffee stinger. I had several virusus and it removed them. Although there gone I had just booted my laptop and it wont let me connect to the internet. It said limited access on the icon. I troubleshooted the windows network diagnostics and it said this. Problem found windows could not automatically detect this networks proxy settings. Whatever I try to run as administrator it will come up with an error saying

C:/Windows/system32/cmd.exe <-that was an example the name changes for different items.

I basically cant use it at all now. I go to the control panel and click right click properties to disable and it will come up with the same error. It also said windows has encountered an error saving the wireless profile specific error: the data is invalid.
