Handling windows Security when accesing webpage

Im trying to make login into a page for making the testing on it. The problem is when opening the page "Windows Scurity" appears and the page does not load till you fill it. Also tried to put the credentials on the link.

It is possible to make some script to wait in background this window and fill it? Calling it before the driver.navigate line?

IWebDriver driver = new InternetExplorerDriver();
                driver.Navigate().GoToUrl("https://www.mywebpage.com/loader.aspx");
                //NEVER REACH THIS PART WINDOWS SECURITY
                driver.SwitchTo().Alert().Accept();

Any solution for this problem?windows security photo
