A few questions:

1. Wouldn't ctrl+alt+del on a windows box show the program running, and let you shut it down? If not, why not?
2. Wouldn't your firewall notify you if this program wanted to call out? (Everyone should have a firewall, IMHO, yes, even if you're on dialup; WinME 4.90.300 for instance tries to call out occasionally, regardless of what options the user sets about updating everything manually; that's the version pre-installed on my box; no, I don't know if any patches for that have been released).
3. If no to both of the above, what is the program? A plugin to, say, Systray or Windows Explorer?
4. Are people using linux at less risk (they tend to be "under the hood" of their computers more)?
5. Are people using Macs at less risk? (any way to find out if the FBI has ported the prog to macs?)

Beau regards, a good article otherwise. I know the FBI is keeping mum about it, "of course." --KQ
