HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options spyware program

Hi i keep have a re-encountering problem that i can easily fix but its a shared computer and i would like to know which piece of spyware is responsible for it. I boot up the computer and it cannot load explorer.exe i goto the registry and remove explorer.exe from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
and everything works but it will happen twice a month.  It would be nice to figure out what culprit is causing this. For now i plan on blocking write access to this key by everyone.

A lot of nasties now hijack Image File Execution Options(IFEO) key. It's now becoming very common. Sometimes instead of explorer.exe, nasties add a subkey "iexplore.exe" so IE won't load if the debuggers pointing to that file is deleted... or hijacks Userinit.exe etc.

Sorry for delayed reply.

If you can lock or change permissions on that key so no one can write or add to it, it would help.

Thanks!
