    Hi need some guidance on which files to remove and how to nail this little F*****.

    Using XP Home SP1 and most recent updates.

    Have run SpyBot S&D 1.2 with 04 March 2004 update.

    Have read and follwed the thread:
    http://www.wilderssecurity.com/showthread.php?t=15913

    IE6 homepage is obviously nnsearch...
    IE6 often locks and won't load pages other than nnsearch.biz

    First download CWshredder from http://www.thespykiller.co.uk then Run it
    Close all browser windows, click on the cwshredder.exe then click "FIX" (Not "Scan only") and let it do it's thing.

    Now as CWS installs via the byte verifier exploit in M$ JavaVM, just surfing a page with an infected applet can install it with no user participation. So once you’ve run the above, it is vital that you go here, click Scan for updates in the main frame, and download and install all CRITICAL updates recommended.

    then reboot &

    Run hijackthis, tick these entries listed below and ONLY these entries, double check to make sure, then make sure all browser & email windows are closed and press fix checked

    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://nnsearch.biz/
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://nnsearch.biz/
    R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://nnsearch.biz/
    R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://nnsearch.biz/
    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page = http://nnsearch.biz/
    R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page = http://nnsearch.biz/

    O4 - HKLM\..\Run: [xyrsl] C:\WINDOWS\xyrsl.exe

    Reboot into safe mode by following instructions here: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406
    then as some of the files or folders you need to delete may be hidden do this:
    Open Windows Explorer & 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 untick "hide extensions for known file types" . Now click "Apply to all folders"
    Click "Apply" then "OK"

    Delete these files

    C:\WINDOWS\xyrsl.exe

    then
    Reboot normally &

    Download and unzip or install these programs/applications if you haven't already got them. If you have them, then make sure they are updated and configured as described

    Spybot - Search & Destroy from http://security.kolla.de
    AdAware 6 from http://www.lavasoft.de/support/download


    Run Sybot S&D

    After installing, first press Online, press search for updates, then tick the updates it finds, then press download updates. Beside the download button is a little down pointed arrow, select one of the servers listed. If it doesn't work or you get an error message then try a different server

    Next, close all Internet Explorer and OE windows, press 'Check for Problems', and have SpyBot remove all it finds that is marked in RED.

    then reboot &

    Run ADAWARE

    Before you scan with AdAware, check for updates of the reference file by using the "webupdate".
    the current ref file should read at least 01R279 31.03.2004 or a higher number/later date

    Then ........

    Make sure the following settings are made and on -------"ON=GREEN"
    From main window :Click "Start" then " Activate in-depth scan"

    then......

    click "Use custom scanning options>Customize" and have these options on: "Scan within archives" ,"Scan active processes","Scan registry", "Deep scan registry" ,"Scan my IE Favorites for banned URL" and "Scan my host-files"

    then.........

    go to settings(the gear on top of AdAware)>Tweak>Scanning engine and tick "Unload recognized processes during scanning" ...........then........"Cleaning engine" and "Let windows remove files in use at next reboot"

    then...... click "proceed" to save your settings.

    Now to scan it´s just to click the "Scan" button.

    When scan is finished, mark everything for removal and get rid of it. (Right-click the window and choose"select all" from the drop down menu) then press next and then say yes to the prompt, do you want to remove all these entries.

    reboot again

    then post a new hijackthis log to check what is left
