Strange explorer.exe Found

J

Jerry McMorran

Hi all,

I'm using WinXP Pro.

When I opened the task manager, I found 2 instances of explorer.exe.
After further investigation, one is the normal one C:\windows\explorer.exe, one is C:\windows\system32\explorer.exe

I'm afraid of directly deleting that strange one from my hard disk because I don't know whether it is really normal or not. When I
searched the registry with the string "system32\explorer.exe", only one result is found:
Location = HLM\software\Microsoft\Windows NT\CurrentVersion\Winlogon
Name = Shell
Value = c:\windows\system32\explorer.exe

By the way, I heard from some BBS that the software StyleXP is related to "system32\explorer.exe". And as I'm using StyleXp too, I
really don't know whether I should manually delete that "system32\explorer.exe" or not.

Could someone help me?
I've put all the information of my investigation here, see if you have any idea:

Thanks in advance!

Jerry,

Number one, after looking over your HijackThis log, you have stuff
you may niether want or need. You have lots of SCUMWARE!!!

Here are just a few:

C:\WINDOWS\System32\ctfmon.exe {Not scumware, but a resource waster if you
don't need it}

Thanks, Wesley.
I've removed those unnecessary scumwares.
What should I do with explorer.exe now?

Hi Jerry,

Reboot, if you haven't since removing, and run HijackThis again and see what
it finds. Some of this stuff is like the plague, it keeps coming back.

Post your new HijackThis log at your link.

Did I see a Firewall?

You *should* have two explorer.exes
C:\WINDOWS\explorer.exe
and
C:\WINDOWS\system32\dllcache\explorer.exe

File version: 6.0.2800.1106
Size: 980 KB (1,004,032 bytes)
================

The explorer.exe that should be running is in this registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell REG_SZ Explorer.exe
===========

Something you can try.
This opens Task Manager:
Ctrl + Shift + Esc | Highlight: explorer.exe | End Process button |
Answer Yes |
You lose everthing except your Desktop wallpaper.
If that doesn't happen | repeat for the other explorer.exe |
When you do lose everything | With the Task Manager open | File | New Task
(Run..) |
Type: explorer.exe | OK |
Your Desktop and Taskbar will reappear.

Don't try to delete either one. XP won't let you anyhow.
You probably still have crapware on your system.

Hi Wesley,

I think you may have mis-understood my meaning.
I not only have TWO explorer.exe, there are actually THREE.
1. C:\WINDOWS\explorer.exe
2. C:\WINDOWS\system32\dllcache\explorer.exe
3. C:\WINDOWS\system32\explorer.exe
#1 & #2 is the same file with version 6.0.2600.0 & size 977KB.
#3 has no version tab page & its size is 84KB only.
Here is the screen-shot of its look:
http://blueboy1.hp.infoseek.co.jp/explorer_bad.jpg
I've zipped & uploaded that explorer.exe here, you may download & take a look:
http://blueboy1.hp.infoseek.co.jp/explorer.zip

And the explorer.exe that is written in this registry key of my registry is:
H_L_M\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell REG_SZ C:\windows\system32\explorer.exe

And there are TWO explorer.exe running in my Task Manager, they are #1 & #3.

Do you have any idea about that strange explorer.exe?
Can I delete that file directly? What should I do to solve this problem?

Thanks in advance!

Jerry,

I did misunderstand. I understand THREE.
[[you may download & take a look]] No thank you.

If when you right click it and it has no version tab, I would suspect
SCUMWARE. It has the wrong icon. It's the wrong size. It's in the wrong
folder. No legitimate program would name something the same as the Windows
shell. ad infinitum.

Since you know which one it is,
Ctrl + Shift + Esc | Highlight the INCORRECT explorer.exe |
End Process | Go to C:\WINDOWS\system32 | Locate explorer.exe |
Highlight it | Shift + Delete | Answer Yes |
Reboot and see if it's still around.

If you can't delete it this way, start in Safe Mode and repeat above to
delete it.
