    Ok the ntvdm means your App is a 16 bit app. That should not be the issue.

    Your issue is:

    1. You have someone trying to damage the system either an employee or from outside hacked in.

    Did you translate what lm4ku migh mean?

    (I am Fu*king you) sorry I don't know from what country you are from.

    Just wanted to know if you caught that.

    You should unplug the network cable on this station so it don't boot up when fixed and send Malware across the network.

    Below is steps to fix it. But you need to know that your entire system may be compromised and take steps to look for this logon plus deep inspection on all stations.

    Update all Firewalls Virus scanners and other security measures you have and increase the security.

    There are 2 steps to try.

    First there may be a backup in the root of C: boot.bak if so it can be copied to boot.ini.

    If the above don't exist or don't work do the below.

    Secondly boot from 2K cd choose Recovery console and run Fixboot.

    When it boots then you need to use a CD or Flash drive to get Malware repair tools on this computer and check it thoroughly before connecting it back.

    We will help you with that.

    Let me know.


    EDIT: Saw introduction and now know where you are from!:)
