Problem with Malware; just can't shift it!

    Hi there. This is my first post so appologies if this is wrong.

    In Late July, My machine picked up a piece of malware which used the smss.exe file name to disguise itself. However this was recently eliminated thanks to a combination of Spyware Doctor, Spybot S&D, Ewido, AdAware and AVG. It was completely removed from the system.

    However, my computer now has a curious problem (we originally thought it was part of the original infection, but as it is still continuing we aren't so sure.) The problem is that the computer is generating spam through Microsoft Outlook. We use Outlook to communicate with our ISP and a few other addresses, but most of our mail goes through gmail/hotmail accounts. Unfortunately however, we cannot delete Outlook even if we wanted to!

    The Mail always takes a simmilar form (see the attached screenshot) and are easily blocked through a set of Outlook 'mail rules' which prevents them from spreading to other machines, and deletes them instantly.

    The spam is generated at apparently random times, sometimes even when the machine is off. I believe that the malware may have invaded Outlook's .Dll files but I'm not sure if that is possible or not!

    Basically, does anyone know what's happening to my computer? And what can I do about it!

    I've gone through all the steps in the 'what to do' thread, but the problem is still with me! I wasn't able to post a Panda log as it said the machine was clean and didn't give me the option. Or was I not looking hard enough? (if so just say the word and I'll do another scan.) The other problem I had was that I was unable to run Bitdefender and Panda in anything but normal mode. Will this have made a large difference?

    Please find attached the screenshot of the email(s), The GetRunKey & ShowNew logs. I'll post the Bitdefender and HijackThis logs in the next post.

    Edit: The pic was attached in a rather odd way, here is the link instead:

    Thanks for all your help!

    Here are the Bit Defender and HJT logs, like I said, I'll rerun the Panda scan if you want.

    Thanks.

    Well it's been a day since I ran all the tests etc. and Outlook is still producing spam, this should confirm that it isn't due to any viral activity.

    Welcome to Majorgeeks!

    You need to follow the directions in step 7 of the READ ME and make sure that you are not using MSconfig to control startups. Please run MSconfig and select Normal Startup. Then attach new logs from GetRunKey and HijackThis. You were hiding a load of stuff we need to see.

    You should also goto Add/Remove programs and uninstall the below old version of Sun Java:
    Java 2 Runtime Environment Standard Edition v1.3.1_01
    Java 2 Runtime Environment, SE v1.4.2_03


    Also I have a couple questions!

    Is the below really for iRiver? And why is it installed like this to be running from the root folder? And does it need to always load and run at startup?

    O4 - HKLM\..\Run: [iRiver Updater] \Updater.exe


    Do you recognize the below URL to be valid?
    O17 - HKLM\System\CCS\Services\Tcpip\Parameters: SearchList = stoke.ramesys.com,crick.ramesys.com

    Thanks for your reply.

    Here are the 2 new .txt files, I hope this helps! I've also deleted the old Java 2 stuff.

    As for the questions;

    1. Yes this is from Iriver. I've no idea why it needs to load & run at startup; as far as I'm aware it doesn't need to (it is very rarely used anyway.) It's been like this since it was installed I believe.

    2. Yes the Url is valid, (it relates to my father's previous job) but I belive it has not been used for some time, would it be worth deleting it anyway?

    Thanks,

    John Wedge

    You attach new logs from GetRunKey and ShowNew. I needed a new log from GetRunKey and HJT so just attach a new HJT log now that msconfig is disable.

    If you don't need that URL line for an old job, we will remove it. As for the iRiver update, you don't need to run it. You can get the updates for it manual when desired. We will fix that too later after I get the new HJT log.

    Start by downloading - - Pocket KillBox

    Extract it to its own folder somewhere that you will be able to locate it later.


    Run HijackThis and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now (some of these may no longer be found if the uninstalls above worked):

    O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime

    After clicking Fix, exit HJT.

    Now run Pocket Killbox by doubleclicking on killbox.exe
    Choose Tools > Delete Temp Files and click Delete Selected Temp Files.
    Then after it deletes the files click the Exit (Save Settings) button.
    NOTE: Pocket Killbox will only list the added files it is able to find on the system. So when you do the below, if some files do not show in the list after pasting them in, just continue.

    Select:
    • Delete on Reboot
    • then Click on the All Files button.
    • Please copy the file paths below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy):

    C:\WINDOWS\System32\stlbdist.DLL
    C:\WINDOWS\System32\ydocsm.exe
    C:\WINDOWS\uptodate.exe
    C:\Program Files\Power Scan\powerscan.exe
    C:\WINDOWS\NastySex.exe
    c:\program files\internet optimizer\sim\msbb.exe
    C:\Program Files\ISTsvc\istsvc.exe
    C:\Program Files\Internet Optimizer\optimize.exe
    C:\WINDOWS\System32\dp-him.exe
    C:\WINDOWS\dcxkvsl.exe
    C:\Program Files\ClearSearch\Loader.exe
    C:\WINDOWS\System32\bdit142k.exe
    C:\documents and settings\helen\local settings\temp\AZ1jp.exe
    C:\Program Files\AutoUpdate\AutoUpdate.exe
    C:\WINDOWS\Adult_Chat.exe
    C:\WINDOWS\System32\Sfr88l14.exe

    • Return to Killbox, go to the File menu, and choose Paste from Clipboard.
    • Click the red-and-white Delete File button. Click Yes at the Delete on Reboot prompt.
    If you receive a PendingFileRenameOperations prompt, just click OK to continue (But please let me know if you receive this message!).
    If Killbox does not reboot just reboot your PC yourself.

    After reboot locate the below folders and delete them if found:
    C:\Program Files\Power Scan
    c:\program files\internet optimizer
    C:\Program Files\ISTsvc
    C:\Program Files\ClearSearch
    C:\Program Files\AutoUpdate

    Also delete all files in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\TEMP\
    C:\Documents and Settings\John\Local Settings\Temp\

    Now attach a new HJT log and tell me how the steps went.

    Also attach a new logs from ShowNew and GetRunKey.

    Make sure you tell me how things are working now!

    Hi there.

    I've got as far as deleting all the temp files using killbox, but I've run into a rather daft problem; every time I try to use the 'paste from clipboard' option, the blue text informing me that it may take some time appears for a brief second, then nothing happens. When I attempt to use the 'delete files' button, Killbox says I have't selected any files to delete.

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Let's see if a one at a time copy and past works. You may have a problem with copy and paste and may need to use the browse function in Killbox to locate each file one at a time.

    Now run Pocket Killbox by doubleclicking on killbox.exe
    Choose Tools > Delete Temp Files and click Delete Selected Temp Files.
    Then after it deletes the files click the Exit (Save Settings) button.
    Now back on Killbox's main window, Paste the below filenames into KILL BOX one at a time. Check mark the box that says "Delete on Reboot" and checkmark the box "Unregister DLL" (If available) Click the RED X and it will ask you to confirm the file for deletion…say YES and when the next box opens prompting you to reboot now...click NO...and proceed with the next file. Once you get to the last one click YES and it will reboot. Note some of the files listed below may not exist but we need to check for them anyway.

    C:\WINDOWS\System32\stlbdist.DLL
    C:\WINDOWS\System32\ydocsm.exe
    C:\WINDOWS\uptodate.exe
    C:\Program Files\Power Scan\powerscan.exe
    C:\WINDOWS\NastySex.exe
    c:\program files\internet optimizer\sim\msbb.exe
    C:\Program Files\ISTsvc\istsvc.exe
    C:\Program Files\Internet Optimizer\optimize.exe
    C:\WINDOWS\System32\dp-him.exe
    C:\WINDOWS\dcxkvsl.exe
    C:\Program Files\ClearSearch\Loader.exe
    C:\WINDOWS\System32\bdit142k.exe
    C:\documents and settings\helen\local settings\temp\AZ1jp.exe
    C:\Program Files\AutoUpdate\AutoUpdate.exe
    C:\WINDOWS\Adult_Chat.exe
    C:\WINDOWS\System32\Sfr88l14.exe


    If Killbox does not reboot or if you get a Pending Operations type error message just click OK to continue and then just reboot your PC yourself.

    Then continue as instructed in my previous message.

    The one-at-a-time c&p system seems to have worked fine; all the files were deleted. In addition, the folders:

    C:\Program Files\Power Scan
    c:\program files\internet optimizer
    C:\Program Files\ISTsvc
    C:\Program Files\ClearSearch
    C:\Program Files\AutoUpdate

    Had been removed, The two temp folders were both cleared without any problems.

    Here are the attached logs, it is a little early to tell whether or not this has succeeded in shifting the problem, but I will inform you as soon as I know the answer either way.

    Should I continue to run the machine in 'normal' startup or should I reactivate MSConfig?

    Thanks.

    Remain in normal startup! But you are not in Normal Startup anyway. You have 3 services unchecked from loading at startup (they look like things related to Symantec Proxy Service, Norton Internet Security Stats, and Norton Firewall ). Even though it may look like MSconfig is in Normal Startup mode these registry entries indicate those services are unchecked.

    Why do you want to use MSconfig? Exactly what is it that you do not want to run at startup. MSconfig is not supposed to be used for permanent disabling. It is meant only as a temporary debugging tool! If you don't use software, uninstall it. If you don't want or need it to load at startup, configure the program not to load at startup. If it does not provide an option to not load at startup, then you can use HJT to remove the registry key from the startups.

    A tool like this Startup CPL should be used to control startups otherwise.

    Are your copies of Spyware Doctor and Ewido free trials or paid version? You should not keep Spyware Doctor, Ewido, and Windows Defender all installed. Only one should be used.

    Your logs are clean! You need to tell me how things are running now.

    Truth be told, until you asked me to deactivate MSConfig I didn't know what it was or that we were even running it. I have no idea why it was running in the first place; I'll ask my father as it's his old machine.

    Spyware Doc & Ewido were both free trials. They've both been uninstalled now.

    I just checked Outlook and the problem is still there! I've recieved 4 emails since using killbox, all of which arrived while the computer was off. However, we've been assured by our ISP that the spam is comming from this machine and not from elsewhere.

    Is it possible that a corrupt .dll file is to blame, or would all the checks have picked this up?

    Well did you fix what I was saying now?

    The Received time is when your ISP received them. You need to find out when they are sent. You need a more detail mail header report. A spammer could just be sending your spam and they could even spoof (fake) your IP address. Did your ISP actually have an experience person check to make sure that your address is not being spoofed.

    Do you have other user accounts, are they all having this problem?
    If you do not have another user account, can you create one and give it a mail address and see if it gets spammed.

    No to part 1? And no the check don't look for corrupt DLLs. They look for malware.

    John Wedge Private E-2

    Yep, it's all been sorted.

    Unfortunately I'm not too familiar with Outlook; can I obtain more information via the program (i.e. do I just change some settings) or do I have to install something. As far as I know, my ISP checked to make sure I wasn't being spoofed, but this raises another question.
    If I was being spoofed then why was I receiving the mail, rather than it simply being sent out to my address book?

    If you mean Outlook accounts, the Spam is being sent to various addresses within the @unholytrinity.plus.com domain. As for other accounts on the machine, there are 3 others, but only 2 of us have Administrator status, and one account hasn't been used for several months.

    This is probably the part where you bash your head on the keyboard. Should I run all the checks, scans etc on each user, or simply on the main account (mine) when the problem has most probably come from?

    p.s. appologies for the late reply; I've been away for a few days.

    I don't really use Outlook so I'm not sure. But you would need to have more experience at doing this tracing. Just looking at expanded header info is not suich an easy thing to do. DID YOU ask your ISP to check to see if your address is being spoofed.

    Your account is the email address that is known to the spammer. Thus they are spamming you. They don't have the address in your email address book, they have yours.


    But my question is, are any of the other user accounts on this PC being spammed. If not, and also based on the fact that you say others in your domain are being spammed, it sounds to me like your problem is from an external spammer and not a problem local to your PC. This is not anything out the normal for spammers. Once you are on one list, you get on dozens of more lists. And if you ever respond to one their emails or click a link that tells you click this to remove from our list, you just confirmed your email address is valid and got yourself added to more lists.

    John Wedge Private E-2

    I've sent them another email, with any luck they'll get back to me soon.

    The account I'm using now (mine) is the only account that has access to Outlook that I'm aware of. I'll check the unused account and see if this is being spammed. Though I'm not sure if this account has Outlook access either.
     
  18. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Can you create a new user email account to your ISP? Usually they allow you to have 5 to 6 email addresses that the main account (I assume this would be your account) can set up. If you setup a new account, obviously no one would have the email address yet since it is new. Thus it could not be on any spammer lists yet. If it starts having the same problems right away, then your PC could definitely be infected. But the downside of this is that, if it does not have the same problem, it does not prove that your original account is not infected. If only would mean at the higher level (the PC level) there is no infection but a particular user account could be infected. But based on what I saw in your logs, you are not infected. Your address is just known to spammers. A solution for this would be to actually change the user account email handle to a new name. Then no one would have it. Then do not use this account on any questionable sites and do not give it to anyone unless you trust them with your email address. Friends who are careless in protecting their own PCs could easily have their email address books stolen. This can get anyone in their address book added to spam lists.
