This is necroposting, but I had the same problem -- virus broke the MS-help protocol. Fix is easy enough, but I couldn't find it on Google. Perhaps this will help someone.
The key for ms-help was deleted. First you have to find the CLSID. Do a search in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\ to find the "hx protocol class". I couldn't find it searching for that, so I searched the registry for help (or hxds.dll) until I found it. You have to click on the CLSID to see the name of the thing. Mine was {314111c7-a502-11d2-bbca-00c04f8ec294}, but that might change between machines.
Anyone, once you have the ID, go to HKEY_CLASSES_ROOT\PROTOCOLS\Handler\. Create a new key named ms-help. Add a new string called CLSID and paste in the CLSID, with braces. You can look at the other protocol handlers to see how they are formatted if you get confused.

My ms-help protocol is broken too. Glad that it's not just me. mshelp
protocol handler seems to be missing where I would have thought there would
be "HKEY_CLASSES_ROOT\PROTOCOLS\Handler\mshelp". Anyone know what should be
there? Perhaps a CLSID?

The mshelp:// links don't have a protocol handler, and won't work in IE (not
to be confused with ms-help:// links, which DO work in IE)
The images worked when I first installed Vista, but something has since
broken them. I just spent a few hours comparing a working system to mine,
then trying to break it. I didn't have any luck breaking it on the "good"
machine
or fixing it on the "bad" machine.
I looked through my list of installed software and tried installing anything
that might mess with Internet or help settings - MSDN Document Explorer,
Office 2007, Firefox, Nero, Adobe CS2, the latest Windows Updates.
Everything worked
fine. Deleting the merged help indexes didn't break the good machine or
fix the bad one.
It's not user specific. I created a new user, which had the same problem as
my logon. This should also rule out IE settings.
Using Process Explorer, the file versions of everything loaded into the
HelpPane.exe were the same between the two machines, though the bad
machine didn't have as many DLLs loaded (I'm assuming that's because the
images weren't actually loaded). Comparing
traces from Process Monitor didn't show anything obviously wrong. The
traces were different, but no obvious file not found or access denied
messages. There are lots of GUIDs and "expected" registry keys not found,
so I'm not 100% sure I didn't miss something.
Unfortunately, none of this information actually fixes anything - I'm just
sharing what I did to see if it helps anyone else troubleshoot this issue.
