    You will need to download the following tools and have them ready to run.
    Do not run any of them until instructed to do so:

    http://www.ewido.net/en/

    * Install ewido.
    * During the installation, under "Additional Options" uncheck "Install background guard" and "Install scan via context menu".
    * Launch ewido
    * It will prompt you to update click the OK button and it will go to the main screen
    * On the left side of the main screen click update
    * Click on Start and let it update.
    * DO NOT run a scan yet. You will do that later in safe mode.



    Click: http://castlecops.com/zx/flrman1/cwsserviceremove.zip to download
    cwsserviceremove.zip and unzip it to your desktop.


    Download Killbox here: http://www.thespykiller.co.uk/files/killbox.exe and
    save it to your desktop.


    Click here: http://cwshredder.net/bin/CWSInstall.exe to download
    CWSinstall.exe to the desktop.


    Click: http://www.downloads.subratam.org/AboutBuster.zip to download
    AboutBuster created by Rubber Ducky.


    Unzip AboutBuster to the Desktop then click the "Update Button" then click
    "Check for Update" and download the updates and then click "Exit" because I
    don't want you to run it yet. Just get the updates so it is ready to run
    later in safe mode.


    Now go ahead and set your computer to show hidden files like so:


    Because XP will not always show you hidden files and folders by default,
    Go to Start > Search and under "More advanced search options".
    Make sure there is a check by "Search System Folders" and "Search hidden
    files and folders" and "Search system subfolders"

    Next click on My Computer. Go to Tools > Folder Options. Click on the View
    tab and make sure that "Show hidden files and folders" is checked. Also
    uncheck "Hide protected operating system files" and "Hide extensions for
    known file types" . Now click "Apply to all folders"
    Click "Apply" then "OK"


    ______________________________________________________________________

    Sign off the Internet and remain offline until this procedure is complete.
    Unplug your modem or disconnect the cable or phone line. Copy these
    instructions to notepad and save them on your desktop for easy access. You
    must follow these directions exactly and you cannot skip any part of it.
    ______________________________________________________________________


    Click Start > Run > and type in:

    services.msc

    Click OK.

    In the services window find Network Security Service (NSS)
    Right click and choose "Properties". On the "General" tab under "Service
    Status" click the "Stop" button to stop the service. Beside "Startup Type"
    in the dropdown menu select "Disabled". Click Apply then OK. Exit the
    Services utility.



    Note: You may get an error here when trying to access the properties of the
    service. If you do get an error, just select the service and look there in
    the top left of the main service window and click "Stop" to stop the service. If that gives an error or it is already stopped, just skip this step and proceed with the rest.

    ______________________________________________________________________
    In Hijack This, click on the "Open Misc Tools section" button. Next click the
    "Delete an NT service" button. Copy and paste the following in that box:

    11Fßä#·ºÄÖ`I

    Click OK.


    Restart to safe mode.

    http://service1.symantec.com/SUPPOR...001052409420406

    Perform the following steps in safe mode:
    ____________________________________________________________________

    Double click on the cwsserviceemove.reg file you downloaded at the beginning to enter into the registry. Answer yes when asked to have its contents added to the registry.
    ____________________________________________________________________

    Go to Start > Run and type Hijackthis. Press enter to start HijackThis.
    DO NOT OPEN ANYTHING ELSE!



    Put a check by these entries in Hijack This and click the "Fix Checked"
    button:

    O23 - Service: Network Security Service (NSS) ( 11Fßä#·ºÄÖ`I) - Unknown owner - C:\WINDOWS\system32\syshg.exe


    Double-click on Killbox.exe to run it. Now put a tick by Standard File Kill.
    In the Full Path of File to Delete box, copy and paste each of the following
    lines one at a time then click on the button that has the red circle with the
    X in the middle after you enter each file. It will ask for confirmation to
    delete the file. Click Yes. Continue with that same procedure until you have
    copied and pasted all of these in the Paste Full Path of File to Delete box.



    Note: It is possible that Killbox will tell you that one or more files do not
    exist. If that happens, just continue on with all the files. Be sure you
    don't miss any.


    C:\WINDOWS\sdkal32.dll
    C:\WINDOWS\system32\crwh32.dll
    C:\WINDOWS\system32\atlbj.dll
    C:\WINDOWS\system32\syscn.exe
    C:\WINDOWS\system32\syshg.exe

    ___________________________________________________________________


    Next run aboutbuster. Double click aboutbuster.exe, click OK, click Start,
    then click OK. This will scan your computer for the bad files and delete them.
    _______________________________________________________________________

    Finally, run CWShredder. Just click on the cwshredder.exe then click "Fix"
    (Not "Scan only") and let it do its thing.

    _______________________________________________________________________

    * Run Ewido:

    * Click on scanner
    * Click Complete System Scan and the scan will begin.
    * During the scan it will prompt you to clean files, click OK
    * When the scan is finished, look at the bottom of the screen and click the Save report button.
    * Save the report to your desktop

    ________________________________________________________________

    In safe mode navigate to the C:\Windows\Temp folder. Open the Temp folder and
    go to Edit > Select All then Edit > Delete to delete the entire contents of
    the Temp folder.

    Go to Start > Run and type %temp% in the Run box. The Temp folder will open.
    Click Edit > Select All then Edit > Delete to delete the entire contents of
    the Temp folder.

    Finally go to Control Panel > Internet Options. On the General tab under
    "Temporary Internet Files" Click "Delete Files". Put a check by "Delete
    Offline Content" and click OK. Click on the Programs tab then click the
    "Reset Web Settings" button. Click Apply then OK.
    _______________________________________________________________________



    Boot back into Windows now.



    Go to: http://housecall.trendmicro.com/ and do an online virus scan.

    Be sure and put a check in the box by "Auto Clean" before you do the scan.
    If it finds anything that it cannot clean have it delete it or make a note
    of the file location so you can delete it yourself. Housecall will detect
    the leftover files from this hijacker.


    This hijacker is known to alter or delete certain files so check this out
    please:


    Download the Hoster from:
    http://www.funkytoad.com/download/hoster.zip UnZip
    the file and press "Restore Original Hosts" and press "OK". Exit Program.


    If you have Spybot S&D installed you will also need to replace one file. Go
    to: http://www.spywareinfo.com/~merijn/winfiles.html and download
    SDHelper.dll. Copy the file to the folder containing your Spybot S&D program (normally C:\Program Files\Spybot - Search & Destroy)


    Check in the C:\Windows\system32 folder to be sure you have a file named
    Shell.dll. If you do not have one, go to the C:\Windows\system32\dllcache
    folder.


    Find shell.dll and right click on it. Choose Copy from the menu.
    Open the System32 folder and right click on an empty space in the window.
    Choose Paste from the menu. Otherwise, you can download following the
    instructions here: http://www.bleepingcomputer.com/files/shellxp.php


    control.exe may have been deleted.
    See if control.exe is present in C:\windows\system32


    If control.exe isn't there, go to:
    http://www.richardthelionhearted.co...es.html#control, and download
    control.exe per the instructions at the site.


    IMPORTANT!: Please check your ActiveX security settings. They may have been
    changed by this CWS variant to allow ALL ActiveX!! Reset your ActiveX security settings like so... Go to Internet Options > Security > Internet, press 'default level', then OK.
    Now press "Custom Level."
    In the ActiveX section, set the first two options (Download signed and
    unsigned ActiveX
    controls) to 'prompt', and 'Initialize and Script ActiveX controls not
    marked as safe" to 'disable'.
