    I am having problems with my computer and have discovered through AVG that my computer is infected by multiple Trojan Horses as listed below. I have scanned and cleaned with AD-AWARE and scanned with HiJackThis. The HiJackThis Log is also listed below. The main problem so far is that I cannot access Notepad.exe. Thanks in advance for your help.

    first Turn off system restore by following instructions here
    http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001111912274039

    That will purge the restore folder and clear any malware that has been put in there. Then reboot & then re-enable sytem restore & create a new restore point.

    then empty temporary internet file

    IE/tools/options/general/press delete files and tick include offline content

    then
    download CWshredder from https://www.wilderssecurity.com/showthread.php?t=14086 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.

    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 &
    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

    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\System32\dp-k13w13.exe
    C:\windows\temp\v.exe <<<< select everything in the temp folder and delete it all
    C:\documents and settings\Rob\local settings\temp\bdl14025 <<<<< select everything in the temp folder and delete it all
    C:\WINDOWS\System32\bridge.dll
    C:\WINDOWS\emsw.exe
    C:\windows\system32\notepad.exe

    then
    Reboot normally &

    Empty recycle bin
    using windows explorer go to C:\WINDOWS\system32\dllcache and copy notepad.exe and then paste it into C:\WINDOWS\system32 to replace the infected one you removed earlier, also paste another copy in C:\windows and if windows asks allow it to overwrite the existing file

    then run a full anti virus scan and post back with the results please
