Building on my previous suggestion: https://kagifeedback.org/d/9316-automatic-checking-of-search-results-against-virustotal
Domains that are flagged as malicious should prompt the user before they are navigated to the search result. This would help protect users from phishing and malware by providing a clearer warning that they have to acknowledge before visiting the site.
For any domains flagged by VirusTotal (again, building off this), a warning message should be shown to the user when they click on a result from those domains.
Something like "This domain has been flagged as malicious by VirusTotal. Are you sure you want to proceed?" And then with two options: "Cancel" and "Proceed anyway"
