(CNN) -- Google says it will spend $5 million on an effort to wipe pictures of child sexual abuse from the Web and another $2 million to research more effective ways to find, report and eradicate the images. "The Internet has been a tremendous force for good -- increasing access to information, improving people's ability to communicate and driving economic growth," Jacqueline Fuller, the director of Google Giving, said in a blog post. "But like the physical world, there are dark corners on the web where criminal behavior exists." Part of the $5 million will go to established child-protection groups that have been partnering with Google to fight the problem. They include the National Center for Missing and Exploited Children and the Internet Watch Foundation.
