VirusTotal Scan is an anti-spam and anti-spy add-on for Firefox that enhances security by allowing users to scan URLs through multiple virus scanners. This subscription-based tool leverages the capabilities of VirusTotal to provide comprehensive analysis results. Users can simply right-click on any URL and select the VirusTotal Scan option to initiate the scanning process, making it user-friendly and accessible for anyone concerned about online security.

The add-on is designed to display scan results conveniently in a new window by default, with an option to configure results in a new tab for improved usability. It requires permissions to access data from virustotal.com and to send notifications regarding scan progress or any errors encountered. This ensures that users remain informed throughout the scanning process.
