The default behavior of ASP.NET is to write unhandled exceptions to the event log. The way to prevent it from writing them to the event log is to handle them yourself. You can do this via your Global.asax file in the Application_OnError handler.
You can also call Server.ClearError() to prevent it from bubbling up to any other handlers.
