Hello dear @tmagames
You can submit a request to Microsoft to let them know that your site is legitimate.
If I am a website owner, how do I correct a warning on my legitimate site?
You can immediately submit a request for a correction. Microsoft Defender SmartScreen has a built-in, web-based feedback system in place to help customers and website owners report any potential false warnings as quickly as possible. In Windows Internet Explorer, from a red warning, click More information then Report that this site contains no threats. This will take you to a feedback page where you can indicate you are a site owner or representative. Follow the instructions and provide the information on this site to submit a site for review.
To report feedback from the Internet Explorer Download Manager, Right-click on the blocked download and choose Report that this file is safe. This will take you to the feedback page.
Once a dispute is submitted, a team of graders inspects the site in question. All disputes should be submitted through the website reporting process to ensure the quickest resolution.
In Microsoft Edge, click More information then Report that this site does not contain threats.
What can I do if SmartScreen warns me about a site I visit, but it’s not unsafe?
From the warning page, you can choose to report this site as a safe site. Select More information, and then select the Report that this site does not contain threats link to go to the Microsoft feedback site, and follow the instructions.
If you visit a site that you think SmartScreen should warn you about in the future, you can report it to Microsoft by tapping or clicking the Tools button, pointing to Safety, and then choosing Report unsafe website.
