Dear Jørgen Christiansen

Thank you for reaching out to the Microsoft Q&A forum. I'm sorry to hear about the issue you're experiencing with your website being incorrectly flagged as unsafe by Microsoft Defender SmartScreen. 

Microsoft Defender SmartScreen is designed to protect users from potentially harmful websites and downloads. In case you are confident that your website is legitimate and safe, you have two options to address the issue: Report the false warning to Microsoft and Temporarily turn off Microsoft Defender SmartScreen.

1. Turn of Microsoft Defender SmartScreen 

• Open Microsoft Edge. 
• Click the three-dot menu in the top-right corner and select Settings. 
• Go to Privacy, Search, and Services → scroll down to Security. 
• Toggle Microsoft Defender SmartScreen to Off. 

Note: Disabling SmartScreen may expose your device to malicious websites or downloads. This is not recommended unless you fully trust the site. 

2. Report to Microsoft  

• Visit the Microsoft report page: Report an unsafe site - Microsoft Security Intelligence (the language of this link is English)
• Enter the URL of the flagged website. 
• Select the type of incorrect warning:  
• If flagged as phishing → choose Phishing 
• If flagged as malware or suspicious behavior → choose Malware or other threats 
• Choose the primary language of the website (e.g., English, Norwegian). 
• Complete the CAPTCHA to verify you're not a robot. 
• Submit the form. 

Note: Microsoft will review the site and, if confirmed as safe, will remove the warning within a few days. 

Important: Ensure your website uses a valid SSL certificate, contains no malicious code, and passes security checks 

I really hope that the information I gave above was helpful to you. Please feel free to reply below and let me know if you have further concern on this matter.
