HELP! Login/logoff loop problem!

    I have a big problem - two of my home machines seem to have been hit with
    some kind of virus. When I type my password to login it immediately logs me
    off. All I can see is my desktop background flash on screen before it logs me
    right off.

    I found some articles on fixing this like these:
    http://www.winxptutor.com/wsaremove.htm
    http://techrepublic.com.com/5208-11...=160649&messageID=2208716&tag=content;leftCol

    however I got a big problem - I dont seem to have a copy of userinit.exe to
    copy! it simply does not exist on that machine or the recovery console can't
    see it!

    To make this even worse I wanted to try using my KNOPPIX Linux boot cd to
    try and see if I can get a userinit.exe file in there from another PC but
    that PC wont boot the linux either!

    What frustration... can anyone provide any ideas on how I an resolve this? I
    dont have any floppy drives so that's out. I have USB flash drives but
    without being able to boot windows or linux I can access them

    Have you successfully used this Knoppix live CD before? On this PC? If
    the answer to the first question is no, there very well may be something
    wrong with the CD. If the answer to the second question is yes, it
    sounds like a hardware problem.

    As you found out, this is most likely a userinit.exe problem caused by
    malware. Either the file does not exist or its registry reference points at
    the wrong location. I would fix it by creating a Windows 7 boot CD (yes,
    Windows 7!), then boot the machine with it to get a Command Prompt. This
    will give you full access to the hard disk. You can then run regedit.exe to
    examine and fix the userinit reference if necessary. Ask a friend with a
    Windows 7 PC to burn a 32-bit Repair CD for you or get one from here:
