Macbook and iTouch don’t connect to the internet. Where’s the problem?
I have owned my black macbook for 2+ years. It has served me well despite laggish operating speed. I come back one day to connect to the internet on my computer and it doesn't work, but it has full signal. So I test my Itouch (gen2) and it has the same symptom...I tested the server with a different computer and it worked perfectly fine...Any thoughts?

You might have spyware on it. Try Spybot Search And Destroy from the link below, if it doesn’t work try it in safe mode.
