multiple trojans and malware - yieldmanager

    Hi, I wonder if you could help please?

    I have followed your READ ME FIRST thread as far as I can, with a view to getting rid of mainly Yieldmanager. Unfortunately, although I have got as far as uninstalling Java, (version 6.17), I cannot now install the update of Java6 version 20. I get an error message, Error 25099 - unzipping core files failed. I looked this up on the java help, and it said to delete C\ProgramFiles\Java\jre6 - which I did, and to download the update again, which I also did.. same error..

    What should I do now?

    To give you a bit of background, I am running Windows XP service pack 3, with full AVG (not free version), with AVG firewall, and Spybot Search and Destroy. Windows firewall is turned off, as is system restore.

    I have, as usual with YieldManager, been getting pop ups on my system - when I first downloaded AVG to clean these, (after running Housecall and not finding it), AVG found two trojans - cannot remember the names of them now as I have emptied the vault at least 3 times in the last 2 weeks. Since finding and quarantining these 2 trojans, my system has been over-run with trojans and malware - its as if quarantining these two spawned a whole host of others! I've taken off over 70 trojans and hundreds of malware instances.

    Last run of AVG, in the early hours of this morning, found and healed/quarantined the following:

    Malware:
    Yieldmanager (numerous entries)
    Atdmt (lots again)
    Serving-Sys
    WebTrends
    Adtech
    Adviva
    Tribalfusion
    Dealtime

    and these trojans:
    Exploit_c.DSO (3 instances)
    Crypt.WCI (4 instances)
    SHeur3.YNJ (2 instances)
    SHeur3.ZRB
    Backdoor.ircbot.MKU
    Crypt.WSG

    Also, when I uninstalled Java, as directed, AVG popped up straight away with a critical notice, and forced a restart on C:\Documents and Settings\Ali\ApplicationData\YCEKT, saying it had found 3 trojans (Crypt.WSG, Exploit_c.DSO (x2)). When the system had rebooted, I opened AVG and it said while quarantining those, it had terminated 74 processes (I never have more than 56 in my task manager), removed 38 files, and deleted 2 registry keys - no info as to what.

    So.. where do I go from here? Can I follow the rest of the steps in your READ ME FIRST thread without installing Java?

    Any help would be greatly appreciated - I've been battling this for nearly 3 weeks now and it's getting kind of wearing :(

    Regards

    Hello - I've run into some problems with combofix. It says to turn off or disable antivirus, antispyware and firewall before running... I'm running full AVG with firewall. Although I can and have disabled the firewall, I can't find any setting which allows me to disable the antivirus or the antispam or the online shield components. I've tried taking them out of task manager and they just come back in immediately. The only option I can see is to uninstall AVG completely, but I don't really want to do that as I'd have to pay for it again. Can anyone give me some quick advice? Should I skip ComboFix (although I am definitely running 32bit windows)? Should I run ComboFix with AVG still running? or is there an easy way to take AVG out of the start menu and still put it back again later?

    I know.. I'm such a non-geek... *sighs*

    Thanks in advance for your help

    Re: multiple trojans and malware - yieldmanager - LOGS attached

    Hi
    I've finished the READ ME Cleaning process, the logs are attached. RootRepeal wouldn't extract so I couldn't run it. The others ran fine with no problems.

    After finishing the cleaning process I ran AVG and it's still finding YieldManager, among others. I've pasted the scan results below so you can see what's still on here. I'm thinking the Trojan AVG found is just that it doesn't recognise MGTools and thinks it's a virus, but I could easily be wrong!

    Also, since running ComboFix, I have no start menu. Neither AVG nor SpyBot will now load as resident scanners unless I start them manually, and all my tray icons have gone. I've also lost the 'file' toolbar from IE. I haven't tried to re-install java yet - if you remember from my previous post, after deleting the java6 version17, the install of 6.20 failed with error 25099 - unzipping core files failed.

    I forgot to mention earlier what SpyBot found last night:

    MyFreezeToolbar
    Win32.ZBot
    PlayMP3z
    Virtumonde.prx
    WhenUSearch
    WhenUSearch.Desktoptoolbar

    It said it had healed these, but somehow I doubt it!

    Also, if anything, since running the cleaning process, my system is running slower than ever. IE hangs for a while before it will load pages, and if I try to open something in a new tab the new tab comes up as 'connecting' but stays blank, and the page requested comes up in a new window. If I try and close either the blank tab or the new window, it takes out all the pages and closes IE totally.

    Here's the scan results from AVG run just now:

    Cookies are not problems and yes avg flagging MGTools.exe as a baddy was a false positive.

    I cannot see that any of the scans have caused this.

    Try this for avg and spybot S&D:

    Adding Programs to your start up folder

    You might as well delete these old files for old versions of avg.

    • c:\program files\avg75free_485a1117.exe
    • c:\program files\avg70free_344a618.exe

    Now we need to use ComboFix
    • 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.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    DirLook::
    c:\documents and settings\Jali\Application Data
    c:\documents and settings\Jali\Application Data\Olutd
    
    Folder::
    c:\documents and settings\Jali\Application Data\Avyn
    c:\program files\Free Offers from Freeze.com
    
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}]
    
    • 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.
    • 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.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this.

    Let me know how the machine is running now.

    Hi,

    Thank you so much for your reply Kestrel - You have advised that I run ComboFix but specified that I disable the AV. I said in an earlier post that I couldn't find a way to disable my AV fully when running ComboFix... I can disable the firewall, identity protection, email scanner, resident shield and the online shield components of AVG 9.0 - but that still leaves the Antivirus, antispam, anti spyware and the rootkit still running. Other than uninstalling AVG I can't see a way around this - is there anything else I can do to disable AVG?

    I do take your point that cookies are not problems, but these cookies are ones I have had for weeks now, and even though AVG and SpyBot say they have got rid of them, they keep coming back. I'm not visiting these sites, and other than your forum I have not been on ANY sites tonight since running the cleaning programs. I emptied the temp files and the cache earlier before starting the cleaning process, so why are they still in there? They are all Ad sites too.

    Any advice re: disabling AVG would be very welcome! :)

    Regards

    Jali

    Please see the below and then complete the fix I provided for you with combofix.

    How to disable AVG Free temporarily


    (should be of a similar vein for the paid for version)

    Hi Kestrel

    Many thanks for your help :)

    Both logs attached.

    I followed the instructions in the link you posted about adding programs to the start menu, and put shortcuts to both AVG 9.0 and Spybot in there, but neither icon has come up. The machine does seem to be running a little smoother and faster, but still I have the problems that the file tool bar has gone from task manager and from IE. Also the tabs have gone from task manager so I can only view processes and nothing else.

    Regards

    I think you may have alot of issues that will be more suitably worked out in the software forum. I am not seeing alot else to do here, let's just try this:

    Now we need to use ComboFix
    • 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.

    • If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    File::
    C:\WINDOWS\DCEBoot.exe
    Folder::
    c:\documents and settings\Jali\Application Data\Olutd
    
    • 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.

    • I will ask for this log below

    Note:

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

    Now run this:

    GMER - running with a random name


    Run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from GMER.

    Hi Kestrel

    Thank you for your reply. I will run the ComboFix again as you asked, but thought you should know that things aren't so smooth running as I thought last night.

    This evening, when opening a new tab in IE or clicking on a link to open another page other than the first opened IE page, I get either a new tab that won't open, says 'connecting' but doesn't, and just whites out both pages, or I get a new seperate webpage that again whites out and won't connect. The system just hangs, and I have to force it to close in task manager by knocking out iexplore.exe (multiple versions of iexplore in the task manager). I ran both AVG and SAS again, and neither found anything, other than the same yieldmanager and other ad page cookies that were there last night. But, just now I checked in system tools and found that system restore had turned itself back on, even though I had it disabled yesterday.

    Heading off now to run the fixes you asked for.. back in a bit! :)

    Thanks once again :)

    Hi Kestrel

    Just a quick update before I head for bed - it's 5am and my eyes are square from staring at monitors all day and most of the night too!

    After posting the logs I did a windows update, including IE security fixes, and when I opened IE after the reboot I finally got a button on my toolbar giving me the option to put my file bar back! So I tried bringing up task manager, and that's gone back to normal too. I took out the google toolbar extension from IE, and the problem with the non loading/whiting out tabs seems to have gone! Although I'm not holding my breath... rolleyes

    I managed to install java again.. this time it didn't fall over during the install. The only thing I haven't managed is to get my AVG and Spybot resident tray icons back. Although I have managed to pin them both to the start menu now.. When I check task manager though, although AVG's numerous processes are there, I can't find any Spybot ones. Not a TeaTimer in sight! So I really don't think it's running. At least I have AVG back and active.. I'll perhaps try a re-install of Spybot tomorrow. That's me done for the night.. work in 4 hours!

    Thanks to your very patient and expert help I think the end is finally in sight... Fingers crossed for clean logs! :major

    All in all, not a bad night's work.. see you on the flip side.. :zzz

    Kestrel13! Super Malware Fighter - Major Dilemma Staff Member

    Yes those logs look good to me. Any issues you now have with avg can always be discussed in the software forum.

    One last question:

    What is this seen on your desktop?

    xn2wymib.exe

    Hi Kestrel

    Thank you so much for all your efforts and help. The pc is a lot more stable now and it isn't crashing like before, and IE seems to be working ok, but it is SLOW - Much, MUCH slower than before I was virused. I'll head over to the software forums and see if there's anything they can do to help perhaps! :)

    xn2wymib.exe - that's the random name GMer called itself when I downloaded it. You had me confused for a while as there's nothing called that on my desktop, but when I did a search, GMer came up!


    Can I ask one more thing? Perhaps it might be more suited to the software forums, but.. Is it usual to have more than one instance of IE in task manager? I've not used IE much, as I prefer alternate browsers, but as they stopped working when I was virused, I switched back to IE. I've never noticed multiple iexplore.exe's in my task manager before. Last night I had 2 tabs open in IE, and 3 iexplore.exe's in task manager.. and I have noticed this a lot recently, with sometimes up to 6 or 7 iexplore.exe's. It doesn't seem related to the number of pages open.

    Once more, thank you so much for your help. You people do a wonderful job here!! :cool

    Kestrel13! Super Malware Fighter - Major Dilemma Staff Member

    You're welcome. Yes do head on over to the software forum to persue this.

    rolleyes Oh silly me, yes.

    Yes, post in the software forum regarding this.

    You're most welcome. :) Safe surfing.

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:

    Hey Kestrel

    Thanks for this.. You've been great!
