Lots of malware infections are through visiting web pages which hosts them, when you open these kind of websites, your machine might be infected. BitDefender Traffic Light is a nice freeware tool which is actually a cross browser app which prevents web threats through websites. TrafficLight intercepts and scans web traffic before it even reaches the browser, effectively blocking disguised or stealth attacks before it’s too late.
When you visit any webpage using browser, it shows a pull down menu at the top and this menu shows whether the webpage is safe for browsing. TrafficLight works with virtually any Windows-compatible browser. It even keeps look, feel and functionality consistent if you switch browsers.
TrafficLight won’t block an entire website if just some pages within are malicious. Only the potentially harmful elements are blocked, leaving you free to view the rest of the site if you so choose. Using the settings, you can choose what all needs to be blocked while browsing.
TrafficLights works on Windows XP, Vista and Windows 7 and on browsers Internet Explorer 7+, Opera, Mozilla Firefox, Google Chrome and Safari.
