No new process starts a few minutes after going online

  1. I had a recent virus attack in my system which i solved using avg. But a strange problem is affecting me now. A few minutes after I log on to the internet, I can not get any other process to start. I click on the exe file icons in vain.Even Task manager wont open. Mind you, the system doesn't hang, the existing processes run fine and there doesn't seem to be excessive CPU activity. Initially I thought it was a virus, so I ran Avg scans over and over again, but could not detect a thing. I also tried scanning the system with AdAware and Regrun reanimator, but they don't show any infections either.

    I found out that the command prompt worked fine , so I installed a command line process viewer to see a list of the running processes when the system stopped responding to exe files. I saw that while that there were no suspicious processes running , the unresponsive files have only one open thread. ex if I click on the taskmgr icon after the system has become unresponsive, the process viewer shows that the taskmgr process has indeed been created but has managed to open only 1 thread. I can not seem to fix the problem. Any help in this regard would be appreciated.

    scan from another computer not possible

    Unfortunately , I don't have another computer at my disposal... I'll try an online scan if that helps.

    I tried to run hjt while the system was unresponsive.I had the hjt window open beforehand. But the scan did not proceed beyond
    04 - registry and start menu autoruns

    The scan hung midway... I find myself more and more clueless.

    Your HJT log looks clean.

    However, do you recognise these entries as being from your ISP?

    O17 - HKLM\System\CCS\Services\Tcpip\..\{54EB3C52-C22E-4166-9C98-BA98B2396827}: NameServer = 61.1.96.69,61.1.96.71
    O17 - HKLM\System\CCS\Services\Tcpip\..\{E51F17D0-8C16-4DB9-9381-A02ADDE95503}: NameServer = 218.248.240.208 218.248.240.135
    O17 - HKLM\System\CS1\Services\Tcpip\..\{54EB3C52-C22E-4166-9C98-BA98B2396827}: NameServer = 61.1.96.69,61.1.96.71
    O17 - HKLM\System\CS2\Services\Tcpip\..\{54EB3C52-C22E-4166-9C98-BA98B2396827}: NameServer = 61.1.96.69,61.1.96.71

    Only fix the above, if they don`t belong to your isp.

    I need to have a more in depth look at your system.

    Please download Deckard's System Scanner (DSS) and save it to your Desktop.
    DISCONNECT FROM THE INTERNET...REMOVE THE PLUG FROM THE BACK OF THE COMPUTER

    Close all other windows before proceeding.

    This means TURN OFF ALL other security programmes.
    Norton Anti-virus, AVG Anti-spyware or any other security programmes you`re running.

    Double-click on dss.exe and follow the prompts.
    When it has finished, dss will open two Notepads main.txt and extra.txt -- please attach the main.txt and extra.txt in your next reply.

    Re-enable your security programmes and reconnect to the net.

    Regards Howard :)

    Your system is infected with some very nasty malware, including a rootkit and a backdoor trojan.

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.


    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).

    .exeOnly end the process that says .exe only
    mmdmm.exe
    sessnmgr.exe

    Close task manager.

    Locate and delete the following bold files and/or folders(if there).

    C:\windows\System32\.exe
    C:\windows\System32\ktbodhzu.bat
    C:\windows\System32\emptyregdb.dat

    C:\Windows\System32\drivers\runtime2.sys
    C:\Windows\System32\mmdmm.exe
    C:\WINDOWS\sessnmgr.exe

    Click start/run and type regedit into the run box and hit the enter key.

    Navigate to the following regkeys and delete the bold portions.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\runtime2.sys

    HKEY_LOCAL_MACHINE\software\microsoft\shared tools\msconfig\startupreg\mmsass

    HKEY_LOCAL_MACHINE\software\microsoft\shared tools\msconfig\startupreg\Windows Images Scanning

    Close regedit.

    Reboot into normal mode and rehide your protected OS files.

    Run a Panda Antirootkit scan as per step11 of the instructions in this thread HERE.

    Post fresh Deckard's System Scanner (DSS) logs as well as the results of the Panda antirootkit scan.

    Regards Howard :)

    Scan results

    Sorry for the delay. I did exactly as you asked but could not find the nameless C:\windows\system32\.exe file.

    Panda anti root kit scan did not find any rootkits, but it did not prompt me to save the results in a text file , do I don't know how to send you the text results of the scan.

    The DSS scan only produced a main.txt file this time.

    But the previous symptoms continue, It still becomes unresponsive to exe files a few minutes after going online.

    Download combofix.exe to your desktop. Double click combofix.exe & follow the prompts. A window will open with a warning. Type "Y" (and Enter) to start the fix. When the scan completes it will open a text window. Please attach that log back here together with a fresh HJT log. Caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop.

    Once that`s completed, please attach the Combofix log.

    Regards Howard :)

    Open notepad and copy/paste the text in the code box below into it:
    NOTE* make sure to only highlight and copy what is inside the quote box nothing out side of it.
    Also ..

    Pay particular attention to this :-

    Make sure the word File:: is on the first line of the text file you save (no blank line above it, & no space in front of it)
    Code:




    Save this as CFScript.txt

    Then drag the CFScript.txt into ComboFix.exe as you see in the screenshot below.

    [​IMG]

    This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply.

    combofix report

    the requested report is attached

    That looks fine.

    Click start/run and type combofix /u into the run box and hit the enter key. That should delete Combofix and all it`s folders etc.

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.


    If you have any further virus/spyware problems, please post in this thread.

    still not working

    I have followed all your instructions verbatim, but the symptoms persist. To top it all the system has started showing another strange behaviour. Minutes after going online the system clock changes abruptly. It goes behind by about 13.5 hrs. It is not a hardware problem because this never happens while I am offline.

    Unfortunately, I`m not sure what`s causing your problems as I can`t see anything nasty in your log files.

    I suggest you try the following.

    Click start/run and type sfc /scannow into the run box and hit the enter key.

    Windows will now search for any missing or damaged system files and replace them as necessary. You will need to have your Windows cd handy as Windows may ask for it.

    If that doesn`t help, then try a Windows repair as per this thread HERE.

    Please let me know the results.

    Regards Howard :)
