About the extension

VirusTotal Domain Monitor gives you a practical, browser-native way to keep an eye on domain reputation without constantly opening VirusTotal by hand. Add your own domains to a watchlist, let the extension check them on a schedule, and use the badge to understand the current site's status at a glance.

When a domain is flagged, you can open the record, review vendor verdicts, and start dispute work directly from the side panel. The extension is designed around the free VirusTotal Public API, so the workflow stays realistic for solo webmasters and small teams. It spaces requests, shows daily usage, supports pause mode, and keeps data locally in the browser.

This extension does not block websites, does not replace antivirus software, does not inject warnings into pages, and does not use its own reputation backend. It is a focused monitoring tool for people who manage sites and want an operational view of domain reputation.
