Success!!!!
In addition to my external clone drive (F), I have a second internal drive
(E) that I had cloned my IE7 based system on before I downloaded IE8 so I
could easily return to IE7 in case I had problems with IE8. To my delight,
it had the uncorrupted add/remove list. The "missing" item on my (C) drive
list was the GeoSoft Hosts Manager (MVPS) entry. I was able to find its
uninstaller on my (C) drive, and after uninstalling it, my add/remove list
is back to normal.
Thanks again to all the help from those of you who responded to my problem.
I learned a lot, including the value of a good backup system that provides
fully bootable clones. FWIW, I use Casper 5.0 for cloning which seems to be
quick (7 minutes, typically) and foolproof.

PA,
I don't believe it is nonsense to live with an add/remove list that has a
big gap in the middle of the list IF this is the only problem that it
manifests. I have tried most all of the suggestions that have been offered
here and have tried several that I have googled. None has removed the
problem. You suggested a format and reinstall as a last resort.
I have a highly customized XP/IE8 installation that would take me a long
time to reconstitute. It has been working relatively trouble-free for
quite
some time. I use Avast! a/v, XP firewall, MVP Hosts file, SpywareBlaster
and do regular scans with Malwarebytes and SUPERAntiSpyware. I update
scrupulously. The recent Trojans I mentioned were the first such
infections
I have had in years. I don't have any idea how they crept in and I don't
believe the Add/Remove problem is connected to them. They have been
removed
and I have done complete re-scans with MWB and SAS and found no other
problems.
So, the tradeoff I face is to start over by dumping a well functioning
(except Add/Remove) system or continuing to use it "as is" and be slightly
inconvenienced with a gimpy add/remove function that I use maybe once a
week. Seems like a no brainer to me.
The biggest problem for me is that I am a bit of a perfectionist and hate
to
have anything about my computer that isn't "right" no matter how trivial.
I
will probably continue searching Google/Bing regularly for a solution.
As always, I appreciate your quick response and sage suggestions.

I also read that a chkdsk may reveal an issue. A refresher:
Right click on the C drive in Explorer and go Properties > Tools >
Check Now (under Error Checking). Check both boxes then click "Start
Now". A message will pop up saying that Error Checking will run after
you restart the computer. Restart the computer and Error Checking will
run automatically after the restart. After it’s finished it will
restart into Windows automatically.
Everything after this is just from tinkering with my system:
Since I can seem to recreate here by changing my registry, I will see
if I can figure out the mystery of the program listed on top of the
empty space and the one on the bottom and what is in between.
What is your last displayed program before the gap and what is the
first after the gap? If revealing does not compromise your
environment. Maybe it is the program that is the first missing one,
but I don't know how to figure out how that Add/Remove list is
presented yet - what program would come after this if things were
working properly...
If you use Add/Remove programs once a week (why?) you can't remember
what was installed between the last time it worked and when it got
broken? If we can't fix the situation the installed program causes,
may just that one can be uninstalled, see if things are fixed and try
a reinstall of that program.
Looks like Add/Remove display sorts alphabetically by default. If
not, sort it that way. For me it goes something like:
....
Adobe Flash Player 10
Adobe Flash Player Plugin
Adobe Photoshop Album
....
I changed the DisplayIcon in Adobe Photoshop Album from 0 to -1.
Now Add/Remove is broken and the last thing before the gap is Adobe
Flash Player Plugin. Then a big (big) gap and things pick up again
normally
I repeated this in the S section.
Look in C:\Program Files, sort by date - what program folders were
installed in the last week/month (I know a program update may change
the date) and maybe you can get a memory jog or help narrow down where
to look. If it is only a couple things and uninstall, reboot, test,
reinstall is no big deal...
Look in C:\Progam Files and sort by name. I have 4 things in my Adobe
folder and one of them was the last thing to display in the broken Add/
Remove. The one I broke on purpose (Photoshop Album) was in there and
(knowing what I know now) would have been the fist thing I would have
suspected as a registry entry to look at, or a program to consider
reinstalling if I could not fix it.
I did the same things with my S entries. Caused a big gap by changing
one S type program DisplayIcon from 0 to -1.
The entire empty space is caused by just one program - everything
before and after it is all still there.
Sorted alphabetically, look in Add/Remove Programs at the program on
top and bottom of the gap - what program is missing? You can probably
tell at least the first letter by now. Look in C:\Program Files - any
ideas?
normal....
Adobe Flash...
(big gap)
Canon...
....normal
The afflicted program is alphabetically somewhere between Adobe and
Canon.
I think the secret is to find the program that would normally occupy
the gap and it appears to be possible to figure that out.
