  2. This can be an adware, which is represented as BHO (Browser Helper Object)
    which hooks DocumentComplete & BeforeNavigate events, since when you go to
    some folder location, these events are fired, adware takes control,
    retrieves the path of a folder, and makes popup.

    Try to change the AV, or try to remove the registered BHO extension.

  4. But usually, I open regedit and look at the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser
    Helper Objects

    It contains list of GUIDS - these are class ids of COM extensions (in a
    simple words, GUID is some long and strange number). Basically, edit the
    GUID, for example, my first GUID is: {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3}

    I just edit it by changing the first elements,
    {BLA49E9F-C8D7-4D59-B87D-784B7D6BE0B3}and then you can try to check, whether
    the bug disappeared or not. If not, restore the original value of GUID and
    play with second GUID.

    Also, remember, that adwares and other crap tryies to restore it's GUIDs in
    BHO registry keys. So, if you delete the entry from registry, it appears
    there again within second. This also can be checked.

    For non-viral malware...

    Please download, install and update the following software...

    * Ad-aware SE 2007




    * SpyBot Search and Destroy v1.4



    * SuperAntiSpyware


    After the software is updated, I suggest scanning the system in Safe Mode.

    I also suggest downloading, installing and updating BHODemon for any Browser Helper
    Objects
    that may be on the PC.

    * BHODemon


    For viral malware...

    * Download MULTI_AV.EXE from the URL --


    To use this utility, perform the following...
    Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
    Choose; Unzip
    Choose; Close

    Execute; C:\AV-CLS\StartMenu.BAT
    { or Double-click on 'Start Menu' in C:\AV-CLS }

    NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
    FireWall to allow it to download the needed AV vendor related files.

    C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
    This will bring up the initial menu of choices and should be executed in Normal Mode.
    This way all the components can be downloaded from each AV vendor's web site.
    The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

    You can choose to go to each menu item and just download the needed files or you can
    download the files and perform a scan in Normal Mode. Once you have downloaded the files
    needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
    during boot] and re-run the menu again and choose which scanner you want to run in Safe
    Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

    When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
    file.

    Additional Instructions:



    * * * Please report back your results * * *

  8. Events from Windows Explorer also fires DocumentComplete and BeforeNavigate,
    and the path is the path from address bar of Windows Explorer.

    I just fixed this problem from my computer a few minutes ago and have
    restarted my system, so this is a verified solution. The problem began when I
    plugged in a USB drive that has been in contact with a public PC.

    Treatment:
    * Run the file 'autoruns' available from the zip file downloadable from
    <http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx>. Go to the
    second tab ('Logon'), untick the entry 'shell.dll.exe' and then right-click
    it to select delete. If warned, give your affirmative to delete. (You may
    want to try deleting it straightaway instead of unticking first, I am just
    retelling how I did it.)

    * in WINDOWS directory (e.g. C:\WINDOWS), remove the file 'shell.dll.exe'
    Note that the file 'shell.dll' - without the .exe extension - should be in
    \WINDOWS\SYSTEM32, \WINDOWS\SYSTEM and \WINDOWS\SYSTEM32\dllcache folders
    [. * go to Task Manager (i.e. press...ll scan. > > > <!--colorc--><!--/colorc-->

    I forgot to add that you will need to change the files-view settings in the
    windows explorer to see the relevant files.

    Go to windows explorer (e.g. by going to My Computer), go the menu Tools
    (ALT-T), click Folder Options..., choose the tab View, activate Show Hidden
    Files And Folders and UNtick the Hide Protected Operating System Files
    (Recommended) and, for the latter, click Yes when they ask whether you are
    sure. Click OK at the Folder Options dialog box.

    Do the opposite after you restart your computer doing the steps in the
    previous post. I.e. DEactivae Show Hidden Files And Folders and retick the
    Hide Protected Operating System Files (Recommended). Click OK at the Folder
    Options dialog box.
