A Dangerous Downloads warning means that the website is serving potentially dangerous software that contains viruses or spyware. Unsolicited Emails on the other hand refers to websites that either send unsolicited emails to users or sell user emails. Sites that are flagged as Browser Exploits will not appear in the search engines anymore.

The options provide a way to change the default Searchscan setting which warns the user from potentially dangerous websites to removing those websites from the search results list or disabling Searchscan altogether.

The warning message appears above all search results to warn the user that some of the websites in the results are potentially dangerous and are also appearing right beneath the title of the website using red text and an exclamation mark icon.

This could help protect users who do not care enough about the dangerous corners of the Internet. I’m not sure on the other hand about the effectiveness of the service. How often is the database updated, how are new sites added to the list ? Still, all in all, it’s good to see that search engines start to take responsibilities.
