BBC NEWS | Technology | Google warns on 'unsafe' websites

Google has started warning users if they are about to visit a webpage that could harm their computer.

The warning will pop up if users click on a link to a page known to host spyware or other malicious programs.

The initiative comes out of a larger project cataloguing programs that plague people with unwanted ads, spy on web habits or steal personal data.

Google is one of several companies trying to act as an 'in-flight adviser' to ensure people stay safe online."
