Not necessarily: I uninstalled and reinstalled Windows Defender in an
attempt to fix the problem, and it's now stuck at Definition version
1.0.0.0 2006/01/25, so my machine isn't terribly well protected.

I'm frankly stunned that this could get released with such a clear
problem, and that Windows Security Support still doesn't know about it
(as of my call 2 hours ago).
