Well I did not use it.
I read and figured that I could take a chance on replacing the file, so I removed the hard drive and put it in another computer with the same XP service pack 3 as Drive D. Then copied the file userinit.exe from the good drive. Took it out and put it back in the orginal computer. Now Malwarebytes says it is O.K. and finds nothing. I am still doing some checking. Let's see if it stays fixed for a day. Did you see alot of junk in the file that i should remove with hijack.
Thanks
