Another smitfraud victim...

    Overview/Intro:

    Smit won't let Firefox run at all! Disgusting little thing. Refuses to die.

    All required logs have been put into the MGLogs.zip file - only one attach.

    I've run SpyBot which finds smitfraud and removes 'svchost.exe' from
    C:\Windows where it 'resides' (hides) after booting into Windows XP. SAS
    does the same. Logs echo the find and removal of svchost in scans.

    The 'good' version of svchost.exe I have is dated 2001 and the file size is
    smaller than the infected file that is found and deleted. Combofix finds and
    deletes it too.

    ----------------------------------------------------------------------
    "C:\WINDOWS\svchost.exe" 22528 10/13/2008 07:48 PM !!!

    "C:\WINDOWS\system32\svchost.exe" 12800 08/23/2001 08:00 AM
    "C:\WINDOWS\system32\dllcache\svchost.exe" 12800 08/23/2001 08:00 AM
    ----------------------------------------------------------------------

    I have tried rebooting into Safe Mode with a command prompt so I can check
    if svchost.exe is there.

    svchost.exe is gone from c:\Windows in Safe Mode with cmd-prompt.

    Once Windows XP is loaded and 'settles' down:

    (1) The infected svchost.exe file is back,
    (2) Firefox will not run or comes up and exits after a few seconds.

    I also tried the online scanner that was suggested.

    Thanks,

    Bill

    Welcome to MajorGeeks, wpaladin

    Please be patient while I review your logs.

    Note: One of the mods will edit out your e-mail addy - not a good idea to post it in the open forums.

    Thanks for looking at my stuff. OK to remove the email address. Quick question:

    Would re-installing WinXP wipe it out? Thanks - BPal, Long Island

    Yes - a "clean install" would.... that's quite a bit of work - to reload everything, IMO. Please advise me if this is what you intend to do.

    No, not ready to re-install WinXP. 'Sides, it does not have SP2 (long story). I do have a large flash drive and a very small hard drive.

    TBC,

    Two files from MalWare Bytes runs are attached. It seems that each time I run MWB, it finds smithfraud. I request removal, it goes ahead and deletes it.
    Does not show in C:\Windows where it usually hides. Then when I re-boot its back.

    Thanks for your help,

    Bill

    Have you disabled your av programs and esp. disabled TeaTimer when you run the SAS and MWB's scans?

    Hello, wpaladin

    Step 1:
    First you need to disable Spybot's Teatimer as requested in the READ & RUN ME. See this: How to disable Spybot's TeaTimer

    After rebooting from disabling Teatimer, continue with the below.

    Step 2:
    Please look in Add/Remove Programs for the following and uninstall if found. If you get any errors just make a note and proceed
    Step 3:
    Now we need to use ComboFix to remove a bunch of malware files.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    
    File::
    C:\WINDOWS\system32\atlcom374_705.dll
    C:\WINDOWS\System32\BCB80684.EXE 
    C:\WINDOWS\svchost.exe
    
    Folder::
    C:\WINDOWS\Gameeeeee.vbs
    C:\Documents and Settings\All Users\Application Data\Viewpoint 
    
    Driver::
    wowsystemcode
    5BB6D41E
    
    Registry::
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
    "QuickTime Task"=- 
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
      If it asks you to overide the previous file with the same name, click YES.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
      http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\\combofix.txt
    • I will ask for this log below

    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    Step 4:
    Run Ccleaner, then re-boot into normal mode


    Step 5:
    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, use right click and select Run As Administrator).

    Then attach the below logs to your next reply:
    • C:\MGlogs.zip
    • C:\combofix.txt

    Make sure you tell me how things are working now!

    Deleting the Java jre's, re-running Combo Fix, disabling TeaTimer etc., seems to have fixed Firefox! Svchost is gone and never comes back. I'd like to make a PayPal contrib.

    How do I do that?

    Hello, wpadalin

    Alittle more work to do....


    Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    Now we need to use ComboFix again.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    
    File::
    C:\WINDOWS\system32\tmp.reg
    C:\WINDOWS\system32\smithf.bat 
    C:\WINDOWS\Gameeeeee.vbs 
    C:\WINDOWS\syscheck
     
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
      If it asks you to overide the previous file with the same name, click YES.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
      http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below

    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    Run Ccleaner, then re-boot into normal mode

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file along with the C:\Combofix.txt log.

    *Also tell me how your pc is running now.

    PC is running fine - very quiet; only 5% CPU utilization or less. I will run the last bat-file you suggested and send logs late today/tonite.

    BTW, smithf.bat I created so that I could look for all copies of svchost. Not a threat:

    dir /s svc*exe

    Thanks for the help,

    Bill

    Thanks for letting me know - newly created files named as such, will draw attention. ;)

    Will give you the final cleanup if there's nothing found in your next logs.

    Windows Messenger util. did not run. Only asked for setup info.

    Logs are in attached zip file.

    The batfile to collect and zip log files was not there so I zipped
    them myself along with the ComboFix log.

    PC still runs smoothly. No popups.

    Thanks,

    Bill

    Yes it is there. It is right where the procedure said it would be. The below is taken right from your logs and it shows the file.
    Code:
