Dear Microsoft Defender SmartScreen Team,

I am writing on behalf of Scanova, the owner and operator of the domain scnv.io, to formally dispute its classification as a malicious website by Microsoft Defender SmartScreen.

We have recently been informed by our customers that scnv.io and its generated short links (e.g., https://scnv.io/7LGB) are being blocked with a "This website is classified as malicious" warning. This classification is incorrect and is causing significant disruption to our customers and their end users.

About scnv.io:

  • scnv.io is the short link and QR code redirect domain operated by Scanova (app.scanova.io), a legitimate SaaS platform used globally by businesses, event organizers, and enterprises
  • Our platform allows customers to create dynamic QR codes and short links for events, marketing, and communications
  • We have an active and growing customer base with paid subscriptions
  • We do not host, distribute, or facilitate any malicious content, phishing pages, malware, or unauthorized redirects

We believe this flagging may be the result of an automated classification error or domain reputation issue, and we respectfully request:

  1. A manual review of scnv.io by your security team
  2. Removal of the malicious classification from Microsoft Defender SmartScreen
  3. Whitelisting of scnv.io to prevent future false positive detections

We are happy to provide any additional information, domain ownership verification, or technical details required to expedite this review. Please do not hesitate to contact us.

Thank you for your time and assistance.

    Microsoft Defender SmartScreen classifications are based on URL reputation, page content, file behavior, TLS security, user feedback, and dynamic behavior. Newly registered or low-traffic domains, redirects, or content patterns that resemble phishing or abuse can cause a domain or specific URLs to be flagged as unsafe, even when operated by a legitimate service.

    To dispute a false positive and request review/removal of the “malicious” classification for scnv.io and its short links, the supported path is to submit the affected URLs/files to Microsoft for analysis:

    1. Collect representative URLs
      • Include the main domain (for example, https://scnv.io/) and several sample redirect URLs that are being blocked.
    2. Submit to Microsoft for SmartScreen review
      • Use the Microsoft Security Intelligence submission site to submit a file or URL for analysis.
      • When submitting for SmartScreen, select Microsoft Defender SmartScreen from the product menu, as documented in the SmartScreen guidance.
      • Provide details that you are the domain owner/operator, describe the service (QR/short-link redirect platform), and explain that the site does not host or distribute malicious content.
    3. Monitor and respond to the determination
      • After submission, sign in to the Microsoft Security Intelligence submission site to check status and results.
      • If the determination still classifies the content as malicious and this appears incorrect, use the developer contact form provided with the submission results to escalate and request re-evaluation.
    4. Ongoing best practices
      • Ensure that any user-generated destinations reachable via scnv.io comply with Microsoft’s malware/PUA criteria to avoid reputation issues.
      • If abuse is detected on customer-created links, remove or block those quickly so that reputation signals improve over time.

    Microsoft does not operate a general “whitelist” or manual allow-list program for developers, and does not accept standing requests to pre-approve all files or domains. However, consistently maintaining a clean reputation and, where applicable, using trusted certificates and secure configurations helps SmartScreen build positive reputation and reduce future false positives.
