How can i stop these questions from being in a google search ?

Hi I previously asked a question about my personal site , but i dont want it to be affiliated with get satisfaction or synthasite. It was my fault for typing my link , i have sinced delted the thread but it still comes up in google when i search my site, will it have been properly erased and will it just take time to disappear from google or is it like hell in the back office of get satisfaction ? any one got any ideas ? thanks
