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.

The warnings will be seen by anyone using the search engine who clicks on a link to a site identified as harmful by the Stop Badware coalition.

Google, PC maker Lenovo and Sun set up this initiative in January 2006 to identify dangerous software and the websites that try to trick people into installing these malicious programs.
