Could you create a gnome applet for Ubuntu, that would use the Kaspersky Security Network to analyze web traffic? In exchange, for contributing to KSN, a user would receive protection from KSN. Web browsers have anti-phishing, but if a user’s web browser gets infected with malware, malware could disable anti-phishing and/or collect and distribute user data to a identity thief. A security app outside the web browser would protect the user from this security risk.
