With the level of malware on Facebook rising on pretty much an hourly basis, it's high time the social network tried to tackle the problem. Facebook is now offering free anti-malware software to its abuse detection and prevention system for users with infected devices. With the support of F-Secure and Trend Micro, Facebook will recommend a download based on the sort of malware detected. Once malware is detected, a notification will pop up including a link to the software in question. Once you click Download, the app will install itself and run. Any results will be displayed as a notifcation within Facebook. The software will uninstall itself when the malware is removed. According to Facebook you can bypass the whole system, but it says it is very likely that you will get the pop up again.
While this is by no means an alternative to full anti-malware software on your PC, it is a great way to combat those annoying links your friends accidentally post when their own systems are compromised. Facebook says it plans to offer "additiona software options in the future," so this could be just the first step towards that.
