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.

Some sites have also included another nasty little payload with this one... Look for paytime.exe folders/app/reg values.

'I got my desktop back to normal, however I am being bombed with pop ups as if I was trying to send an email from outlook and norton would be checking it for virus... Over and over.....the popups emulate the symantec real deal and will read scanning message one of eleven. It will keep on doing it until it fills the entire desktop. Has any of you had this before?'

I'm having the same problem, although I'm pretty sure it isn't just 'emulating' the Symantec e-mail scan...the virus/worm is actually using our computers to send e-mails.

Can anyone help us out with this? Every time my computer connects to the Internet, it automatically starts sending out tons of e-mails.

Explorer.exe is starting with ibm00001.exe as a paramater passed through the system.ini. The f3 find for the text should be able to find it. Open it with notepad and find

shell=explorer.exe ibm00001.exe

delete 'ibm00001.exe'
reboot and should be good

Picture of it here
