So I'm working on a vista machine where 2 user accounts (both with administrative rights) log off just after the log in initiates. As soon as I click the user picture (no passwords) the screen shows "Welcome" with the blue circle. In about 1-2 seconds it changes to "Logging off" then turns black, and then I'm back at the log in screen.

I can log in to them in safe mode, but not normal mode.

I can also log onto the Admin and Administrator acounts without problem in normal mode.

Does anyone know what might be causing this or how I would correct it?

edit: it also has a fake AV trojan on it.
edit: Part of the trojan appears to be attached to the userinit.exe
edit: This is what the log shows:
