Conficker Worm is spreading and dangerous. I'm sure you are aware of it. Since one of the characteristics of the threat is that it blocks access to removal tools, you might want to download a copy of a removal tool ahead of time, even though your OS is patched and you have preventive tools. You never know when a friend might need it! I have it on my desktop for easy mailing if anyone does need it.
