Message Warning CS0108!

Because when I inherit an interface and implement the same methods I get Warning CS0108.

  

Active A variable was declared with the same name as a variable in a   base class. However, the new keyword was not used. This warning   informs you that you should use new; the variable is declared as if   new had been used in the declaration.

For example;

public interface IRepositorioDeValidador : IRepositorio<Validador>
{   
    void Adicionar(Validador validador);
    void Alterar(Validador validador);
    void Excluir(Validador validador);
}

public interface IRepositorio<TEntidade> where TEntidade : Poco
{
    void Adicionar(TEntidade entidade);
    void Excluir(TEntidade entidade);
}

In% with IRepositorioDeValidador and void Adicionar(Validador validador); shows me this message, I know I did not need them in this interface , but it was created like this and I have several cases that way.

Is there any way I can not display the message in my interface that inherits from void Excluir(Validador validador); and is already in this form?
