    Hi Guys

    Looking for your expert guidance ! Problem exists on a laptop used by young kids for school work, playing games etc.

    Initially noted problems with connecting to windows update - 2 weks ago, then noted AV scanner temporarily dectivated about 1 week ago and multiple items unenabled on Spyware Blaster at same time. Thereafter unable to connect to microsoft sites. AV scanner back working, SWB - still problems.

    Ran scans as per your protocol found trojans with SAS - apparently quarantined and removed, then malware found via MBM. Have both on computer and run rsemi regular with minimal findings previously.

    When it came to Combofix - installed MS Rec Console, created restore point, then scanned for 2 mins and hung. Continues to hang at about same point despite reboot, reinstall, in safe mode and rename to Kestrel. There is no log.

    MG Tools file seems small !

    Also tried Trojan Remover unable to install properly - can't find its directory.

    Finally when trying to upload logs to this message - page hung, hence using main computer to send message and logs.

    Thanks in advance

    Run this:

    Go to TDSSKiller and Download TDSSKiller.zip to your Desktop

    • Extract its contents to your Desktop so that you have TDSSKiller.exe directly on your Desktop and not in any subfolder of the Desktop.
    • Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor.
    • Allow the application to run and a window will open showing that it is TDSSkiller from Kaspersky
    • Click Start scan
    • It will run rather quickly and will notify you of whether anything is found or not.
    • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
    Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply. (See: HOW TO: Attach Items To Your Post )

    Now see how you get on with running Combofix and MGTools. Let me know how it goes and attach logs if successful.

    Hi Kestrel 13

    Thanks for your reply. Nil found by TDSS - log file attached.

    Still no luck with ComboFix or MG Tools.

    ComboFix still stalls/hangs - created restore point, saved current info to registry, began auto scan, then stopped after about 2 mins

    In fact MG Tools stops/stalls running first batch file. No further logs made.

    Over to you !

    Run Malware Bytes again and attach the log

    Run SUPERantispyware again and attach the log.

    Download OTL to your desktop.

    • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    • Vista and Windows 7 users Right-click OTL and choose Run as Administrator)
    • When the window appears, underneath Output at the top change it to Minimal Output.
    • Check the boxes beside LOP Check and Purity Check.
    • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.

    When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.

    Attach both of these logs into your next reply.

    Run this and attach the results.

    Using ESET's Online Scanner

    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.

    Find logs below.

    Nil found with SAS & MBAM.

    OTL and Extras for your review.

    Will post ESET log on next reply - nil found.

    Finally GetLogs Bat file began running and then stalled/hung as previous, so no change in MGTools output.

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) 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:

    • O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file)
    • O2 - BHO: NCO 2.0 IE BHO - {602ADB0E-4AFF-4217-8AA1-95DAC4DFA408} - (no file)
    • O2 - BHO: Symantec Intrusion Prevention - {6D53EC84-6AAE-4787-AEEE-F4628F01010C} - (no file)
    • O2 - BHO: Ask Toolbar BHO - {D4027C7F-154A-4066-A1AD-4243D8127440} - (no file)
    • O3 - Toolbar: (no name) - {7FEBEFE3-6B19-4349-98D2-FFB09D4B49CA} - (no file)
    • O3 - Toolbar: (no name) - {D4027C7F-154A-4066-A1AD-4243D8127440} - (no file)
    • O9 - Extra button: (no name) - AutorunsDisabled - (no file)
    • O24 - Desktop Component 0: (no name) - (no file)

    After clicking Fix exit HJT.

    Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.

    Also delete all files in the below bold 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\Darren\Local Settings\TEMP

    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.

    Tell me what malware problems remain.
    Are you able to connect to microsoft sites now?

    I went rhough the logs again, and am not seeing anything in the way of malware.

    There are so many possible causes of problems with Windows Update that it would probably be best to send you to the Software Forum. However, there are a few things we can try first.

    1. Make sure time and date and TimeZone are correct
    2. See if it works in safe boot mode
    3. Reset HOSTS file

    Download HostsXpert and then follow the below steps.
    • Unzip HostsXpert.zip
    • It will create a folder named HostsXpert in whatever folder you extract it to.
    • Run HostsXpert.exe by double clicking on it.
    • Click the Make Writeable? button. (if you only see a Make Read-Only selection, it is already writeable so skip this button).
    • Click Restore Microsoft's Hosts File and then click OK.
    • Click the X to exit the program

    4. flush DNS server

    Right-click on the Command Prompt icon and select
    "Run as administrator". Then type in: ipconfig/flushdns
    and press the Enter key on your keyboard.

    5. add Microsoft URLs to the Trusted Zone (see below)
    6. shutdown firewall and retry
    7. shutdown AntiVirus and try

    MS URLs

    http://*.update.microsoft.com
    http://download.windowsupdate.com
    http://genuine.microsoft.com
    http://go.microsoft.com
    http://support.microsoft.com
    http://update.microsoft.com
    https://*.update.microsoft.com <--Notice the https designation.

    the first thing to always check for Windows Update problems! make sure that Automatic Updates is not turned off. It needs to be on and the service status needs to be Started and the Service type needs to be Automatic.

    You're welcome. :)

    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:
