How to unblock removed threats?

AVG is usually very good about finding threats so when a window popped up saying there was a threat I vaguely glanced over it before instinctively hitting the button to remove said threat. Turns out what it wanted to remove was the executable file for one of my games. Now even if I uninstall and reinstall the game it seems as if AVG will not allow the executable on my computer, making the game unplayable. Is there a way to unblock that file specifically so that I can play my game again?
