Researchers at AntiToxin Technologies found that Bing brought up photos of nude children and would recommend related search terms to users looking for child pornography.

The search engine also suggested similar images when the photos were clicked on.

AntiToxin was commissioned by TechCrunch to investigate the matter, after the publication received an anonymous tip about child porn on Bing.

"Speaking as a parent, we should expect responsible technology companies to double-, and even triple-down to ensure they are not adding toxicity to an already perilous online environment for children," AntiToxin CEO Zohar Levkovitz told TechCrunch.

Microsoft didn't immediately provide a comment about the report, but the software company told TechCrunch it had fixed the issue and said it's working on blocking other problematic searches.

AntiToxin told TechCrunch some of the search terms were still bringing up child porn.
