    Website Blacklisted by Windows Defender SmartScreen But Unable to Determine How to Remove...


    Earlier this week, we started having a website blocked by Windows Defender SmartScreen and Google Chrome. Chrome indicates it is some type of phishing issue. Windows Defender SmartScreen gives us very little information on what caused it or how to resolve it. The only changes to our website recently were some additional text and a couple additional graphics.

    This issue has caused us to have to pause our Microsoft Advertising account completely, and Google Adwords has disapproved every keyword in our account so we are completely down there as well. The website is lemingtonit.com. We need to know immediately why this is happening and what we can do to remove the false blacklist.


    Thank you,

    Defender/SmartScreen warning.

    Though this doesn't explain why an application's specific reputation might have changed, the addition of granular controls for these settings in the recently released Windows 10 Creators Update may have something to do with it.

    Smartscreen in Creators Update

    This newer implementation of SmartScreen within Windows 10 has also been renamed to

    Windows Defender SmartScreen
    rather than the old Windows SmartSreen and SmartScreen Filter name within the browser.

    Again, none of this specifically explains a change in reputation, but it's possible that all of these changes might have affected the reputation for some applications or certificates.

    Since you didn't specify what type of certificate you are using, since this affects the ability to add or gain reputation status more quickly. The

    Windows Defender SmartScreen® Filter Frequently Asked Questions
    page covers this as follows.

    There are industry best practices for application developers that will affect your download's reputation and help ensure reputation is established and maintained. If your program is not digitally signed, reputation cannot automatically be shared
    across different versions and builds.

    To help establish your application's reputation, consider doing the following:

    • Digitally sign your programs with an Authenticode signature

      Reputation is generated and assigned to digital certificates as well as specific files. Digital certificates allow data to be aggregated and assigned to a single certificate rather than many individual programs. Only Authenticode Certificates issued by a Certificate
      Authority (CA) that is a member of the Windows Root Certificate Program can establish reputation.
    • Apply for a Windows Logo

      To learn more visit the
      Windows Logo Program
      page on MSDN.
