Internet users who try to search for illegal child abuse images on Bing will receive a warning message after Microsoft implemented a new ‘pop-up’ system for its search engine.

The US company said anyone that entered a search term from a list agreed with The Child Exploitation and Online Protection Centre (CEOP), would receive a Bing Notification Platform message.

It would warn them the content they were seeking was against the law and would also show them a link to a counselling service.

A Microsoft spokesman said: ‘If someone in the UK tries to use search terms on Bing which can only indicate they are looking for illegal child abuse content, they will activate the Bing Notification Platform which will produce an on-screen notification telling them that child abuse content is illegal.

‘The notification will also contain a link to who will be able to provide them with counselling.’

The action follows a threat from prime minister David Cameron that he would impose tough new laws on some internet firms if they failed to issue certain measures to crackdown on online porn.

The move from Microsoft to issue a message was welcomed by CEOP’s deputy chief executive Andy Baker.

‘While the Bing project isn’t the whole solution, I hope it goes some way to making those who are curious about searching for indecent images think again,’ he said.

According to a recent study Bing only has a 4.99 per cent share of the UK search engine market, with Google having a massive 88.3 per cent share.
