ATAV Safe Browsing by ATDevs Team

If you try to visit a site that has been flagged for malicious or harmful activity, the add-on will block access and display a warning page explaining the reason.

If you encounter a suspicious or unsafe site that hasn’t been flagged, you can report it using the “Report” button.(Toolbar->Puzzle piece icon->ATAV Safe Browsing) Be sure to include details about why you believe the site is harmful. This helps us review and take action more effectively.

If you believe a website is being incorrectly blocked, you can report it as a “False Positive” for further review.
