Problems with prize-wave.com?

i just 'won' a xbox 360 + kinect via twitter but i didn't know but now know i'm in a scam, if i get it soon, does it mean i going to get something like a piece a paper, wanting money, should i throw it away and ingore it and have that gift, and just forget it?, i kinda worry. plus, my pc auto-update because they want my id stuff.
