Removed Spysheriff, now error message 'ibm0001.exe not found'

Your article on Spysheriff is very helpful, however when booting I still get the message ibm00001.exe not found. Any suggestions?


It is unclear if this ibm0001.exe is really related with Spysheriff. When my machine was infected with Spysheriff, I did not have this file on my hard disk.
However, after some research it has been found that they appear to be related. Maybe there are different versions of Spysheriff or different degrees of infestation.

This file is either in the root folder (c:\) or for example here:

c:\Program Files\Common Files\Microsoft Shared\Web Folders\ibm00001.exe

Other files involved are:

If you boot in safe mode and delete this file or if you delete it using a tool which will delete it right at boot time, then you still will have a reference in the registry to this file.

(Look at the registry by starting REGEDIT.EXE from the Run box.)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

This branch has an entry named 'Shell' which should simply say 'explorer.exe'.

In case of an infestation, it will have the ibm0001.exe (or ..) as an argument after explorer.exe, e.g. like this:
  • Shell: explorer.exe "c:\ibm00001.exe"
  • Shell: explorer.exe 'c:\Windows\System32\kernels64.exe'

Modify this registry entry back to 'explorer.exe' only. and delete the file kernels64.exe which may be located either in c:\ or in c:\Windows\System32\

As described in the comments section, there may be a LOT of spaces between the word 'explorer.exe' and the argument. If you just briefly view the entry, then you will not see the argument. Make sure to edit the value.
Alternatively you can also search the registry for occurences of the term 'ibm000'.


If you cannot find the reference in the registry, do not forget to check in your file 'system.ini' as reported by an anonymous user in the comment section. In his case, Explorer.exe is starting with ibm00001.exe as a paramater passed through the system.ini. (This may depend on the various Windows versions.)

  1. Open file SYSTEM.INI with NOTEPAD and press F3 to find it:
    shell=explorer.exe ibm00001.exe
  2. Delete the 'ibm00001.exe' here.
  3. Then reboot and it should be good.

I had spysheriff awhile back and I uninstalled it but I still can't alter my desktop background, occasionally when the computer is shutting off the image I had there pops up just before windows begins to shut off. How can I alter my background image again?

I've got in c:\WINDOWS only a system.ini file that contains very few text. Seems quite strange as i know that system.ini should actually manage the boot-process. This is what it contains:

; for 16-bit app support

No 'shell=explorer.exe' or something... i tried to F3-search this string, but no success. On the other hand, there is a log-file (named setupapi.log) which prooves that following happened:

#-199 Executing 'C:\WINDOWS\explorer.exe' with command line: explorer.exe (lots of spaces...) 'C:\Programme\Gemeinsame Dateien\Microsoft Shared\Web Folders\ibm00001.exe'

Yahoo antispy now will fix the frozen background image problem caused by spy sherriff. Best of all you don't have to edit your registry manualy. This program is free with yahoo tool bar and can be deleted after the problem is fixed if you don't want it.
