I am SO not a technical person.... I was infected as well (currently I am not on my PC). I found the msblast.exe and deleted it, and also deleted it from the regestry. Still no go, so I downloaded the removal tool, and obviously it couldn't scan because the computer kept shutting down. So I opened it in safe mode. Now it could scan. At the end of the scan it said that this worm was not on my computer. Ok, I restart the computer, and guess what - I got the same error and "system will shut down in one minute" or however it's phrased. Any ideas what I can do, other than reformat the computer?....
