Trevor Pottinger, a software engineer on Facebook’s threat infrastructure team, offered more details in a note on the Facebook Security page:
For the past year, we’ve been working with anti-malware companies like ESET, F-Secure and Trend Micro to offer free malware cleanup software to people who use Facebook. Thanks to the collaboration with these companies, in the past three months, we have helped clean up more than 2 million people’s computers that we detected were infected with malware when they connected to Facebook. In these cases, we present a cleanup tool that runs in the background while you continue using Facebook, and you get a notification when the scan is done to show you what it found.
To make this program even more effective, Kaspersky Lab is bringing its expertise to our malware cleanup efforts. If we detect malware on your computer, we will offer Kaspersky Malware Scan for Facebook among our other cleanup tools to help take care of the problem. That means that another leading anti-malware company is helping you keep your computer safe and secure, just by using Facebook. And in the past three months, Kaspersky Lab helped us protect more than 260,000 people accessing Facebook from malware.
