To configure advanced security settings

located at the top-left corner.

Select 'Settings' from the menu > 'Show advanced settings' link.

Clear history and cookies at exit. This setting is disabled by default and clears all history and cookies when the user closes the application.
Do not allow websites to know where you came from (suppress HTTP referrer header). The disable referrer option stops website owners from knowing which URL (website) you visited immediately before arriving at their website. This option is disabled by default. Enabling this option will immediately stop referrer information from being passed to websites that you visit.
Use a prediction service to help complete searches and URLs typed in the address bar. Click the following link to know more about Prediction service.
Predict network actions to improve page load performance. If enabled, Comodo Dragon will look up the IP addresses of all links on a webpage. Then, if you decide to click one of those links, the resulting page will load faster. By default, this option is enabled.
Phishing and Malware Protection. This setting is enabled by default in Comodo Dragon and alerts you if the website that you are trying to browse contains malware or suspected of phishing attacks.
Enable malware domain filtering (Comodo Secure DNS). If enabled, Comodo Dragon will use Comodo Secure DNS servers instead of default DNS servers provided by service providers. Visit http://www.comodo.com/secure-dns/ for more details.
Regardless of whether or not you have chosen the option 'I would like to use Comodo SecureDNS Servers (with all applications)' or 'I would like to use COMODO SecureDNS Servers (in Dragon only)' in step 4 during installation, selecting this option will force Comodo Dragon to use Comodo SecureDNS for malware domain filtering.
SecureDNS references a real-time block list (RBL) of harmful websites. These include phishing sites, malware sites, spyware sites, and parked domains that contain excessive advertising. You'll be warned whenever you attempt to access a site containing such potentially threatening content. Our highly secure infrastructure also reduces your exposure to DNS poisoning attacks.
In addition, enabling Comodo SecureDNS makes the web pages you visit to load faster as Comodo operate a huge network of fully redundant DNS servers located at optimal locations around the world. Your requests for web-pages are always resolved by the high performance DNS cluster closest to you. Hence the websites load faster than if you continue to use the DNS server provided by your ISP (which you share with all their other customers of the ISP).

Send a 'Do not track' request. A 'Do Not Track' request notifies websites that they should not store or profile your online activities. This setting mainly affects 3rd party web tracking companies such as advertising networks, analytical services and social networks. Users should note that the Do Not Track system is voluntary and websites are not compelled by law to honor these requests.
