Dangerous websites are not blocked!

Opera does not maintain its own phishing, fraud, or malware blacklist. If you feel that our browser failed to recognize a fraudulent or malicious website, you can contact the following companies to have the URL added to their blacklists (after they have tested the sites). Opera will then use the updated blacklists as soon as the website is added to it.

You can contact each of the companies here:

Information from Yandex is also used to identify websites with malware, but there is no way to report suggestions to them.
