Just the ot her day I was looking for free downloadable games to play and needless to say I found several and installed them only to find they had spyware/addware included in the exe. The first game is called industryplayer and the other is Wik and the Fable of Souls.
Also if you look for websites for cheat codes for some of the more popular games using http://www.cheatgenius.co.uk/cheatsingame/XBOX_16395_Halo_2_cheats.html as your base address.
Thanks for the heads up-- I'll give that a try. Do you need the actual games installed in order to install the cheats?
