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...
