I think based on further comments in the topic and on the forums, that particular pre version 5 code drop doesn't work completely, but they haven't released an update to that code (certainly not for testing).
However when any anti-kill functionality is released it should make it more difficult, but I doubt it would make it impossible, like anything there are ways round things if you are prepared to devote the time to it.
I think the key is to try and prevent the thing getting established in the first place. Like the use of DropMyRights for any program that you use to access the internet, stop that writing registry entries for the various files, etc.
You could also look at things like CyberHawk or other HIPS options, etc. to add to a multiple-application approach to protection.
If all else fails, you must have a back-up and recovery strategy that can recover from virtually any disaster. I would much prefer paying for a hard drive imaging software than have to contemplate dealing with some of these rootkit infections. Over the last few months I have actually restored my system twice in under 10 minutes using my last weekly image of my hard drive partitions. Compare that to how long it takes to recover from a bad infection or having to format and reinstall everything.
