i bought a new computer and it wouldnt work so i phoned the costomer support and he said it runs better under windows!! so i took it downstairs and put it against the middle of the window because the front room has more light. when i pluged it in it started working, but now my g/f says i have to close the curtains at night because they havent been closed for a month and she is worried about spyware

i told my g/f that if i close the curtains the computer wont work, but he wont let me keep them open, so would my computer still work even if i close the curtains? would it still work if i closed the curtains and put the computer in the middle of the room under the light? or do i need a brighter bulb? would NET curtains stop spyware? can somebody please help me?
