If you want to do one better make sure to run ccleaner after deleting any registry key to nuke any registry keys that may have been relying on it. Run ccleaner 2-3 times and you'll save yourself from a world of hurt.

If you want to do a thorough job of such mitigation as a Q&D fix, you
may also need to nuke the

   HKEY_CLASSES_ROOT\nntp\shell

entry.

I can't easily test the viability of exploiting this via an nntp:// URI
just now, but "nntp" is normally registered (at least with OE -- can
someone check for Windows Mail?) with exactly the same sub-keys and
values as the "news" and "snews" URI handlers...
