    My searchbar/homepage/etc has been taken over.. I ran HijackThis and here's what it found:

    After that I went to C:\Windows\mrhop.dll and opened it in notepad, and found it was related to the "http://searchx.cc/" problem. But this one won't go away.


    Here's a StartupList report too..

    please do this to post the hijackthis log so it can be seen properly

    When you have posted we will delete the link to the image as it breaks the forum layout due to it being too wide

    doubleclick the Hijackthis.exe.
    Click the "Scan" button, when the scan is finished the scan button will become "Save Log" click that and save the log.
    Go to where you saved the log and click on "Edit > Select All" then click on "Edit > Copy" then Paste the log back here in a reply.
    It will possibly show issues deserving our attention, but most of what it lists will be harmless or even required,
    so do NOT fix anything yet.
    Someone here will be happy to help you analyze the results.

    there should be a lot more in ahjt log than that

    you either have it set to ignore some entries or have fixed a lot already

    please do this

    open HJt/config/ignore list press delete all then do a new scan and post the log

    to see if we can prevent the cws hijackers reinfecting you try this
    a workaround seems to be install a good firewall, lists here http://www.wilders.org/firewalls.htm if you haven't already got one and block these ranges of ports, both incoming and outgoing 209.66.114.0-209.66.115.255 and 81.211.105.0-81.211.105.255 and 213.159.117.0-213.159.118.255
    that stops the known cws servers responding or the hidden files on your computer updating. This works sometimes but not always, but it's a help. The problem with this approach is that some good sites might also be blocked

    First download CWshredder from http://www.thespykiller.co.uk

    boot 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"

    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

    Now Run Cwshreddder
    Close all browser windows, click on the cwshredder.exe then click "FIX" (Not "Scan only") and let it do it's thing.


    Reboot After running cwshredder and as soon as possible follow this advice:
    Now as CWS Hijacks are normally installed 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 normally

    Go here:
    http://www10.brinkster.com/expl0iter/freeatlast/PVtool.htm
    And download "Xfind.zip" from there.
    Unzip, run the 'find.bat' inside.
    Wait till it terminates and find 'log.txt' inside which
    you'd need to attach into your next reply.

    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 01R300 28.04.2004 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 along with the log.txt from the xfind

    Thank you sooo much. I haven't gotten to follow through with everything yet but sometime this afternoon I'll definitely try that.
