An interesting addition to last month’s update to Microsoft’s Malicious Software Removal Tool (MSRT) was the ability to detect a virus that entered systems from the Facebook social-network site. Messages enticing Facebook users to watch a video would instead launch the Koobface virus.
Microsoft and Facebook worked together to add Koobface detection to MSRT, as discussed by Jeff Williams in the Facebook blog.
Several people who install the MSRT update each month ask me, “Does this program really do anything?” The fact that you never see MSRT in action is actually a good thing; if you don’t see any malware alerts, your PC probably isn’t infected. In this case, silence is indeed golden.
