    I just spent all day long trying to delete two browser hijacks from my system.

    pmnlk.dll & nnnnkll.dll (both loaded by the Winlogon service)

    I wanted a simpler solution than the HijackThis stuff I've been reading on this website. Don't get me wrong, some of you guys are brilliant, but I wanted something old school. In the old days we just booted up DOS went in and deleted an offending file.

    My problem comes with the fact that all my drives are NTFS formatted. DOS doesn't read NTFS drives. With a lot of searching I came across two excellent FREE programs that did the trick.

    First download a Program called:

    Browser Hijack Retaliator 4.5


    This little gem will Identify loaded "Browser Helper Objects" (BHO's) and show you the associated dll file that goes with it. It will also reside in the background and protect your system from further Hijacks.

    Second dowload a little utitily called:



    Now if you still have FAT32 drives you should be able to use a normal bootdisk, navigate to the folder that has the offending file and use the "del" command to delete it.

    If you have NTFS drives this little program will create a bootdisk for you using FreeDOS
    and its NTFS4DOS addon. Simply boot it up, choose the menu for NTFS4DOS and get a command prompt. Navigate to and delete the offending file just like normal DOS.

    And it WORKS!!! I got rid of both files for good.

    The NTFS4DOS boot disk will also run CHKDSK utilities which is handy when your computer fails to boot. It will allow you to check the disk for errors.

    Also another little jem on the HijackThis site is:


    This program will show you all kinds of stuff. Mainly for me is the "Winlogon autoruns"
    and the "Browser Helper Objects". It will also jump you to regedit to the associated registry entries.

    I hope this helps someone out there because I was at my wits end and wanted to solve this
    problem myself.

    Good Luck!!!
