How to request a review

Website / URL review

Trend Micro's Site Safety Center supports website safety-rating and category reclassification.

  1. Check the affected URL in Site Safety Center and choose Reclassify Request.
  2. Site owners and home users can proceed to URL Reclassification Request; business customers are directed to their support portal.
  3. Choose the proposed safety rating and category, explain your relationship to the site and the reason for review, and enter your email.
  4. Confirm the validation link delivered by email to finish the request.
  • Business customers use the support case category Threat Issue > URL Reclassification.
  • If the product still detects the site after reclassification, Trend Micro asks for the URL and product web-reputation logs through support.

File review

General preparation checklist. A separate vendor-specific workflow for this report type has not been independently checked.

  1. Record the file SHA-256, filename and exact detection label.
  2. Use a listed contact that accepts this indicator type. If the listed route handles a different type, ask the vendor or project for the responsible review team.
  3. Explain why the detection appears incorrect and include supporting evidence. Follow the recipient’s instructions before sending a sample.

Scope & contact notes

  • VirusTotal does not specify an indicator type for this contact. Confirm that the recipient handles your exact file, URL or rule result.
