OREANDA-NEWS. June 29, 2015. Facebook announced Tuesday it has been using a new security tool to help detect and remove malicious software for users of the world's biggest social network.

Facebook said it was working with Kaspersky Lab, bolstering a program implemented with other online security firms including ESET, F-Secure and Trend Micro.

"Thanks to the collaboration with these companies, in the past three months we have helped clean up more than two million people's computers that we detected were infected with malware when they connected to Facebook," said Trevor Pottinger, a Facebook security engineer.
