CDO is the acronym that means that you're using MS web based interface.
And the bad news is that the web based stuff does sometimes add those extra
characters.
I have no idea why it's sometimes and not always.
You may want to switch to a real newsreader (Rick's suggestion).

=============
Sometimes, these newsreaders can't access the newsgroups from behind firewalls
(like at work). If you can't use a newsreader, you may want to switch to
Notepad (instead of MSWord).
There are lots of characters that get mangled when copy|pasting from MSWord into
a plain text message.
