"tu_logonui.exe" problem: Help

  1. Hello,

    My problem is the following: when starting my computer, I have a message telling me that "tu_logonui.exe" encountered a problem and has to close.

    Then, everytime I open any file / application, a windows pop-up appears briefly and tells me that it has to close. Since then, any application I try to open have to close.

    I scanned my computer with several anti malware but the problem is still here... Any help would be greatly appreciated!

    My HiJackThis log is attached.

    Open HijackThis and select Do a system scan only then place a check mark next to:

    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page =
    R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page =
    O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)

    Close all windows and click Fix checked.

    * When the Software Installation dialog box opens. Click on the Install Now button.
    * Follow the prompts to complete installation.

    The tu_logonui.exe has to do with a registry setting that has changed for some reason.

    This post deals with it.

    Thank you Evilfantasy for your help.

    The error with tu_logonui.exe seems to be solved.
    However, my applications keep closing by themselves.

    When looking at the windows error report, it seems that it is related to "kernel32.dll". Do you have any idea to solve this?

    Hard to tell. kernel32.dll could be a number of things.
