Hello, jwes:
I think you want to prevent someone to modify your PowerPoint
presentations, respect the strange behaviour of publishing a pps file
on the web and renamed to pppt when downloaded, please, check that the
link of the page is pointing to a pps file, not to a ppt one. In any
case, this is not a secure method, a pps is not a non-editable
presentation, as you may read below.
By the way, I have found a page that shows you how to protect your
presentations:
Password protect a presentation
http://www.rdpslides.com/pptfaq/FAQ00038.htm
Please note the following paragraph:
"You can't password protect presentations in versions of PowerPoint
prior to 2002"
That means that if you have PowerPoint XP, you can password protect
your presentation to allow anyone view it, but prevent any kind of
edition. If this is not your case here are some alternatives listed on
that web.
-Distribute a show file instead of a presentation file
Rename your presentation from .PPT to .PPS. This doesn't change the
presentation in any way, nor does it really secure it.
-Distribute a show within a show
* Create and save your presentation as a PPS file.
* Open a new presentation, click on Insert, Object, Create From
File and
select the PPS file you just created. Do not check the link or
icon box.
* Resize your embedded PPS (powerpoint show) to cover the whole
screen.
* Use the custom animations setting to make it run automatically,
etc. However you want it to appear.
* Make sure your Multimedia setting is set to SHOW.
* Save your new file as PPS. You may have to experiment a little
to get the exact results you want.
-Zip it
Distribute your presentation inside a password-protected ZIP file or
self-extracting EXE created from a ZIP file. Software and knowhow
about ZIP files here
-Don't distribute your real presentation
Distribute a presentation that contains only pictures of your
presentation. Export each slide in your presentation to a WMF or
bitmap (JPG, PNG, etc.) file, then import each of these files into a
new presentation and scale them up to fill the slide. WMF will usually
make for a smaller presentation, but can be ungrouped and edited to
some degree; bitmap files can't be edited but will make your
presentation file size larger.
-Distribute Acrobat/PDF files instead of PPT files
You can use Adobe's Acrobat or other software to convert your PPT
presentations to PDF files. These can be password protected in two
ways, against opening/viewing the file and against editing the file
and/or copying text and graphics from it.
-Distribute an AVI movie of your presentation
There is also the "convert your PPT presentation to an AVI movie file"
solution. Our screen camcorder and video production tool "Camtasia"
can record anything on the desktop and produce standard AVI files.
Camtasia can also produce Microsoft and Real streaming video files.
For simple screen video capture tasks, also checkout our screen
capture tool "SnagIt".
-Secure Pack
-PrezGuard Pro
-And finally, you can password protect presentations in PowerPoint
2002. Unfortunately, only those who have a copy of PowerPoint 2002
(and your password) will be able to open or view the presentation.
Users of earlier versions of PowerPoint or the Viewer will see a
misleading message suggesting that the presentation file has become
corrupted.
Your case is in the Microsoft's knowledge base:

I hope this is the answer you were looking for and don't hesitate to
request for any clarification or any help implementing the solutions
exposed above.
