Well, the good news is that Microsoft will remove it from your machine in Windows AntiSpyware \ Windows Defender as well as the Malicious Software Removal Tool on the next update. This is important because people with Automatic Updates turned on will be helped, even if they don’t know about Sony’s Rootkit of all evil.
So, I think a few brownie points are in order? Cheers Microsoft! Now, go break Sony’ back.
