win32/heur =(

I downloaded a game from the internet about a week ago and not long after opening the .exe file, i recieved a message about 'win32/heur' virus. I deleted all traces of the game and any files relating to it, however I keep getting the warning about the virus. The warning is about a different file each time, then I delete or quarantine the file only to get another warning later about a different file. My computer is running very slow and the only way I can get any decent use out of it is by booting into safe mode (with networking).
I've read the 'read me' and will attach my log files.
