How to request a review

File review

Webroot's official history records its acquisition of Prevx. The current Webroot file-review process is a route for asking about a legacy Prevx result.

  1. Identify the old Prevx or prevx1 result in the request.
  2. Open the Webroot file-submission page and select False Positive detection as the reason.
  3. Provide the affected file or its hash and the requested context, then complete the CAPTCHA and submission terms.
  4. For a ticket with a contact email, use Webroot support and include the VirusTotal report URL, exact detection and software details.
  • This is a historical engine name; Webroot must confirm whether it can change a legacy VirusTotal result.

Scope & contact notes

  • Listed in VirusTotal search-prefix documentation but absent from the contributor roster snapshot; this is not proof the engine is currently active.
  • This name appears in a VirusTotal engine-prefix list or contact table but is not matched to a current contributor entry. Current engine activity is unconfirmed.
