False alarm

Hello, I was coding something and avast said it was virus:

    class Program
    {

        static void Main(string[] args)
        {
            Console.WriteLine(CountEven(new int[]{2,4,5,6,7,78,6,8,54,33,4,2,1,1,231,45,46,527,3547,3,735,34,42,423,423,56,4362}));
            Console.ReadKey();
        }
        static int CountEven(int[] array)
        {
            return 0; 
        }
    }

And your question is… ?
