Hello Jose,
As by now, the problem appears only inside Windows Explorer.
I don't have many icons on the Desktop, but they all appear correctly.
Also, icons on the taskbar, start menu, a.s.o. are all correct.

The icon for .TXT files was defined by the initial XP installation.
The first time that the problem happened, I tried to replace it using
"Folder Options --> File Types --> Change Icon and I changed it to the icon
of Notepad, that is,
instead of using an icon from shell32.dll, I set it to use an icon from
notepad.exe
and this worked ok.
But, since I am not confortable with that icon, after the problem was solved
I reset the icon back to the original one, the one from shell32.dll.

But, for example the icon for .dll files was NEVER changed, and it comes and
goes
when the problem happens.

Also, I never changed the MyVideo and MyMusic icons, they were only changed
by themselves (to the wrong ones) when the problem appeared, and restored back
when the TweakUI utility succeded in repairing the problem.

It looks to me that, when the problem happens, it is somehow related to the
shell32.dll file, because all the icons that disappear are taken from that
file.
The file shell32.dll looks the same as on the original XP installation CD,
but maybe something prevents it to be read correctly.
This is why when the problem happens, I cannot change any icon (even a
desktop icon) to any icon from shell32.dll, but I can change it to an icon
from another file
that contains icons (ex Notepad.exe).

On the other hand, I know that the icons are stored in IconCache.db,
so, if I understand it correctly, while I am browsing files in Windows
Explorer for
a few hours, and the problematic icons were initially displayed ok, this
means that
those icons are already stored in IconCache.db, so, why are they suddenly
replaced
with the wrong (default or undefined) icons ?
And why do this always happen to the same set of icons, not to others ?

I also found web sites where they suggest that this problem may be related to
some virus or malware ... and they suggest scanning for such viruses using
several tools, because no single tool can detect all of them.
I am using ZoneAlarm with default settings as my security program, and I am
not too familiar with any of these tools.

Could it be a good check if I try to use the computer for some time WITHOUT
connecting to the Internet at all, and then, if the problem does not come
back,
then maybe to conclude that it is indeed caused by something external coming
from the web, and undetected by my AntiVirus program ?

Thanks again a lot for your further help & Best Regards,

Hello Jose,

Thanks a lot for your information.
I hope you don't mind if I will only be able to answer all your questions
when I will be again at my home computer (the one with the problem),
since for the moment I am at my office computer.
I hope I will be able to access this forum from home as well.

Regarding the shell32.dll file, when I said that it looks like the original
one
I meant that its "Date changed" was not altered.
Also, it is not clear to me how is XP capable of putting it back if I rename
it,
except if from the original installation CD.
Does Win XP keep any backup of this and other files on the hard disk ?

I saw on the web some custom replace utilities that can be used to replace
DLL-s,
which are said to work without problems, but you need a replacement DLL file
for using them (usually they say they use it for replacing shell32.dll with
a modified/customized version of it, for which there also exist tools).

When the problem first appeared, my first attempt to repair it was to do an
SFC, which asked for my original CD, and performed a long running scan,
after which it did not report about any problems found.

Next, I understood than XP is supposed to perform an automatic system backup
each time when the OS is updated.
I have automatic check for Windows Update turned on (from the original
installation)
and several times when I turn off the computer it reports that it is
installing one
or more updates before shutting down and this always happens without any
problems.
However, when I tried to perform a System Restore, it told me that it did
not find any restore points available.
Does this mean that I can only create such restore points manually ?

The next attempt, as I already mentioned, was to use TweakUI and to rebuild
the IconCache.db file.

As I mentioned, I will revert when I will be at my home computer, probably
during this week-end.

Thanks again a lot and enjoy a pleasant New Year holiday !
