Spybot detects three registry keys that are related to the Caishow adware program, but I have confirmed that the adware does not exists in my computer. The registry keys detected were in fact related to the game "Command and Conquer: The First Decade" released by EA Games in Feburary 2006. Removal of the registry keys did not affect the game in any way; however everytime I restart my computer the registry keys come back and Spybot detects them again as adware.
