Is there such a thing as hardware spyware? I recently sent my computer to the shop for repair, since then it has been behaving quite strangely and slow. I'm wondering if the shop may have installed a hardware spyware(if there is such a thing) in my hardware to spy and steal my info. Is it possible? Or rather is there such a thing?
I have reinstalled my Windows Vista since then, would that stop the spyware from working if there is one?
Thank you.
