..pf files have NOTHING to do with .pdf files.

Prefetch files are essentially a resource list. Any time a program is
executed, Windows XP will attempt to find a pre-existing prefetch file, and
if it's available, it will use it to make the application load up faster.
The file will also be updated after it is accessed, so that the more an
application is used, the bigger the drop in loading time (to a point). If
the application doesn't already have an associated prefetch file, Windows XP
will create one. Those files are stored in the \%windir%\prefetch directory.
One important note is that the process depends on the Task Scheduler
service. If the Task Scheduler service isn't running, the prefetch mechanism
isn't used and the files won't be read or updated.

What Prefetching does...
[[Windows XP Professional monitors the files that are used when the computer
starts and when you start applications. By monitoring these files, Windows
XP Professional can prefetch them. Prefetching data is the process whereby
data that is expected to be requested is read ahead into the cache.
Prefetching boot files and applications decreases the time needed to start
Windows XP Professional and start applications.
Prefetching is further improved if the files are located next to each other
on the outer edge of the disk. Windows XP Professional optimizes the
location of boot files and applications when the computer is idle. The
optimization occurs in the background and lasts only a minute or two; you
might hear the hard disk being accessed when optimization occurs. After the
initial optimization takes place, subsequent optimization occurs, at most,
every three days.
When you run the Disk Defragmenter tools that are included with Windows XP
Professional, they can perform any optimization updates that are scheduled
to take place during the next idle period. The Disk Defragmenter tools do
not disturb the existing layout of optimized boot files and applications.
Note
Computers running Windows XP Home Edition also prefetch and optimize boot
files and applications.]]

I have decided to turn of XP's Indexing Service on my HD and when I
did that, while it was "applying attributes" to everything on the HD
I got Errors for about 10 files. The Error was "Access is denied."
Two examples of two of the errors:
C:\ProgramFiles\CommonFiles\Ado...\ActiveX
C:\WIN...ADOBEUPDATER.EXE-1AB51BCE.pf
I kept hitting Ignore and saved the first few error windows and then
finally just hit Ignore All.
Have I broken something?
I also went into Services and Disabled Indexing Services there. Is
this OK?

Hi JD,
Your computer may be infected with viruses and malwares, so try to
clean up by scanning on line for both.
For scan online go here:
http://www.pandasecurity.com
http://www.sophos.com
http://www.avast.com
http://www.trendmicro.com
For malwares:
install, then run the updates to get the new definitions and scan for
malwares:

BTW, Adobe extension will end with PDF not PF, the spyware would like
to trick you and your system.
HTH.
Let us know.

That's silly advice; where the heck do you get that idea from?
Rhetorical, don't answer.
So can you or dave explain for me what can help the OP in this matter,
C:\WIN...ADOBEUPDATER.EXE-1AB51BCE.pf, if it doesn't belong to Adobe PDF
and I can't see Adobe will create a profile and call it something else
rather than PDF.
And nobody asked if the OP have Adobe or not?.
HTH.
Let us know.
