explorer.exe being an absolute memory hog

Thanks for the reply, tried it and I'm afraid it didnt work...yes it
registered the dll, but the memory problem still exsists. The PC did have the
Dlder.exe trojan, which I'm told can be part of the problem, that has been
removed and any traces of it in the registry deleted. I think now the only
course of action is to wipe it and start afresh, unless anyone else has any
ideas. Screen res and drivers haven't changed at all. I am sure that the
small icons and the memory prob is linked somehow as the issue only happens
when opening a folder containing pics. Anyway, thanks for trying. Cheers

Sounds like starting over from scratch might be the best (and most
peace-of-mind-ful) solution - it can be with some particularly entrenched
nasties. Are you positive you've got rid of all traces of the trojan and its
effects - what tools have you used to sweep for it and other nasties? It's
best to use more than one - the standard set recommended in these here parts
are Malwarebytes' Antimalware, SuperAntiSpyware and Spybot S&D, as well as a
full sweep with a decent AV product such as NOD32 or, for free, AntiVir or
Avast!.

If you know you've had a specific trojan, it may pay to research it on the
Web, looking for specific instructions for repairing damage it does, which
won't necessarily be limited to the registry.

http://www.google.com/search?hl=en&num=100&q=Dlder.exe+trojan

Description of the Win32.DlDer Trojan Program
http://support.microsoft.com/kb/317013
D1Der.exe was installed in November and December 2001 as an added component
called "ClickTillUWin" with LimeWire, KaZaa, Grokster, Net2Phone,
BonziBUDDY, and some other person-to-person file-sharing software programs.
The trojan program was installed even if you selected not to install any
additional components from those packages during setup. Most software
packages no longer contain DlDer.

NOTE: DlDer is NOT a virus, because it does not spread.

The trojan program downloads the Explorer.exe file, which connects to a Web
site and reports the user's ID (unique for each computer), IP address,
which Web browser a user is using, and each URL that a Web browser opens.
Explorer.exe is installed in C:\Windows\Explorer\ folder.

NOTE: The Windows Explorer executable file is also called Explorer.exe. By
default, it is located in the Windows folder and is not changed or replaced
by this trojan program. Do not confuse the Windows Explorer Explorer.exe
file with the Windows\Explorer\Explorer.exe file (the trojan program).

For more information about DlDer.exe, see the following Web site:

Thank you for all that Info Richard....I have downloaded and installed the
following software to try and fix this issue, Malwarebytes, SuperAntiSpyware,
Spybot S&D, AVG 9.0, HijackThis....I have run the all both in safe mode and
normal mode, all are now reporting a very squeaky clean machine. Have
searched the registry for Dlder.exe and removed the reference. Have deleted
the Dlder.exe file. Deleted all temp files on the PC, deleted all Thumbs.db
to force the computer to re-cache them. No ClickTillYouWin found in the
registry. Nothing running as a sheduled task. Nothing running in startup,
have used msconfig to turn off all un-needed functions, still the problem
exsists in normal and safe mode. The strange part is that the PC behaves
normally under general operation...ie explorer.exe sits around 22k...but as
soon as I open a folder with pics in it, can spike to 120mb or more...this
has got me completely stumped. Thank you all so much for your help this
far...bout to wipe the computer i think. Cheers

Does the problem occur if you switch from Thumbnail mode to a different one,
eg Details? Does it happen for *any* folder with pictures in, or just one?
If just one, try splitting the contents 50-50 into two folders, see if the
memory usage shoots up for just one of those. If so, it could be a problem
with one (or more) of the files, and you could ascertain which by further
50-50 whittling.

Just in case there are video files in the folder(s) in question, and it
might be *those* that are causing the problem, try the related media preview
load/unload command from Start > Run:

regsvr32 /u shmedia.dll

and press Enter. Then the same again, but type

regsvr32 shmedia.dll

and press Enter.

Could well be malware-related, though, and you'll end up starting over.

Hi Anthony,

After a lot of testing, it seems that the spike with explorer.exe may be
normal if you have a lot of pics. In Task Manager (Alt+Ctrl+Del) in the
Processes tab, I clicked View, and Select Columns, and checkmarked:
[Image Name], PID, Memory Usage, Peak Memory Usage, Virtual Memory Size.

I clicked explorer.exe to highlight so it is easy to spot. Since I do not
have any folders with a lot of pictures, I used Search Find Files and
Folders, and searched for *.jpg files, which appeared as thumbnails in the
search results pane. Most had never been displayed as thumbnails before, so
as I scrolled down through the results list, I could see them quickly
changing from generic icons to thumbnails. The MemUsage of explorer.exe was
about 37MB before starting, and gradually increased as I scrolled down
through the search results, and PeakMemUsage got up to 207MB after all the
JPG files had thumbnails. I noted that some of the files from compressed
(ZIP) folders had small generic icons, rather than regular thumbnails.

Another test search with both GIF and JPG separated with a semicolon:
*.gif;*.jpg
found 14,103 objects
Explorer PeakMemUsage= 377,700 K (369MB)
After closing search window, explorer MemUsage= 64,864 K (64MB)

So maybe your 120mb spike is what is supposed to happen.

HTH. (Hope This Helps.
