    I'm running XP. I had a pretty awful Antispyware Soft experience that ended w/ continuous reboots. I got the machine into safe mode, and using a flash drive, have run several anti-virus applications, including Avast!, Malwarebytes', Cyber Defender, and AVG. Avast! was the first to find and remove the threats, but as problems persisted (or, got worse, as getting into Safe Mode has been far more difficult), I found bleepingcomputer and followed their instructions, leading to Malwarebytes. That found more infections, removed them, yet problems persisted. I ran it again. It found an infection. I removed it. Problems persist. I'm running it again. I've found an infection. I suppose I'll try to remove it. I'm also getting a rundll error when I try to start some applications (system utilities, and such). I have no idea where to go from here.

    Hello there :cool: Welcome to the TSG Forums.
    My name is NeonFx. I'll be glad to help you with your computer problems. Logs can take some time to research, so please be patient with me.


    Please note the following:
    • The fixes are specific to your problem and should only be used on this machine.
    • Please continue to review my answers until I tell you your machine appears to be clean. Absence of symptoms does not necessarily mean that the system is completely clean.
    • It's often worth reading through these instructions and printing them for ease of reference. I may ask you to boot into Safe Mode where you will be unable to follow my instructions online.
    • If you don't know or understand something, please don't hesitate to say or ask!! It's better to be sure and safe than sorry.
    • Please reply to this thread. Do not start a new topic.



    Step 1

    Download OTS to your Desktop

    • Close ALL OTHER PROGRAMS.
    • Double-click on OTS.exe to start the program.
    • Check the box that says Scan All Users
    • Under Basic Scans please change the radio button under Registry from Safe List to All.
    • Under Additional Scans check the following:
      • Reg - Desktop Components
      • Reg - Disabled MS Config Items
      • Reg - NetSvcs
      • Reg - Shell Spawning
      • Reg - Uninstall List
      • File - Lop Check
      • File - Purity Scan
      • Evnt - EvtViewer (last 10)
    • Please paste the contents of the following codebox into the Custom Scans box at the bottom
    Code:
    %SYSTEMDRIVE%\*.exe
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll
    iaStor.sys
    nvstor.sys
    atapi.sys
    IdeChnDr.sys
    viasraid.sys
    AGP440.sys
    vaxscsi.sys
    nvatabus.sys
    viamraid.sys
    nvata.sys
    nvgts.sys
    iastorv.sys
    ViPrt.sys
    eNetHook.dll
    ahcix86.sys
    KR10N.sys
    nvstor32.sys
    ahcix86s.sys
    nvrd32.sys
    symmpi.sys
    adp3132.sys
    mv61xx.sys
    /md5stop
    %systemroot%\*. /mp /s
    CREATERESTOREPOINT
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\System32\config\*.sav
    • Now click the Run Scan button on the toolbar.
    • Let it run unhindered until it finishes.
    • When the scan is complete Notepad will open with the report file loaded in it.
    • Click the Format menu and make sure that Wordwrap is not checked. If it is then click on it to uncheck it.
    Please attach the log in your next post. To do so click on the blue "Reply" button or "Go Advanced" and click on the "Manage Attachments" button

    Step 2

    [​IMG] GMER Rootkit Scanner
    Please download GMER from one of the following locations and save it to your desktop:
    • Main Mirror
      This version will download a randomly named file (Recommended)
    • Zipped Mirror
      This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
    • Disconnect from the Internet and close all running programs. Make sure you disable your security programs as well, as they may interfere with the program.
    • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
    • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

      [​IMG]
    • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
    • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
    • Now click the Scan button. If you see a rootkit warning window, click OK.
    • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
    • Click the Copy button and paste the results into your next reply.
    • Exit GMER and re-enable your security programs when done.


    If you have trouble running GMER, please try running it in Safe Mode. To get to Safe Mode you'll need to repeatedly tap the F8 key on your keyboard as you turn your computer on until a black and white menu appears with the option.

    If you continue to have trouble with it, try running it without the "Files" scan checked.



    Again, if the results are really long, please attach them using the instructions I gave you at the end of step 1. This is to avoid having to scroll down the page too much make the space cleaner.

    I should note a few things. I am only capable of using safe mode. If I try to start normally, I get to my desktop, and immediately restart. These scans were done with basic safe mode (as opposed to w/ networking). I'm also logged in as HP, as opposed to Administrator.

    When I ran the GMER, I noticed that only the box w/ my C drive was checked. I have a D drive as well, though windows, and all system info, is on the C drive. There are, however, several other programs on the D drive. I guess I have a J drive too, but I'm not sure what it is. There is a removable drive on the machine, which I have yet to use.

    The GMER, as it seems of a reasonable length:

    Hmm... I can't get the OTS log to attach. It's been half an hour of "uploading," which, for a 184KB file, seems grossly excessive. I can open it just fine, and read it in all it's illegible glory. Am I just being impatient?

    It happens sometimes. You can either try again in a little bit, or use a third party uploader like http://Drop.io and get me the link to where I can find it.

    Good :D Let's do the following:


    NOTE: ComboFix should NOT be used without supervision by someone trained in its use. It does a whole lot more to a system than just remove infected files.

    Download ComboFix from one of these locations:

    Link 1
    Link 2


    * IMPORTANT !!! Save ComboFix.exe to your Desktop



    • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Note: If you are having difficulty properly disabling your protective programs, or are unsure as to what programs need to be disabled, please refer to the information available through this link : Disabling Security Programs
    • Double click on ComboFix.exe & follow the prompts.

      Note: Combofix will run without the Recovery Console installed.
    • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
    • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.


    **Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.


    [​IMG]


    Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

    [​IMG]


    Click on Yes, to continue scanning for malware.

    When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

    Notes:

    1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
    2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
    3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you please let me know. A increasing number of infections are spreading using Autoplay and leaving it disabled is a good idea.
    4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

    Before I get going, I should note that I've been unable to get an internet connection working, even when booting in Safe Mode w/ Networking. It's not that my computer won't try to connect, but for whatever reason, it won't recognize any signals. My only option is a router that I have no control over. I have no phone line, and no way to get at the router. I'm saying this because from reading the above, it looks like it may be a problem.

    Is this a business system? Is that why?


    It's ok to run it without it having access to the internet, but its functionality is diminished because of it.

    You can also dowload the recovery console from a different system and transfer it to this system.

    The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.


    Go to Microsoft's website => http://support.microsoft.com/kb/310994

    Scroll down to Step 1, and select the download that's appropriate for your Operating System. Download the file & save it as it's originally named.

    Note: If you have SP3, use the SP2 package.


    ---------------------------------------------------------------------

    Transfer all files you just downloaded, to the desktop of the infected computer.

    --------------------------------------------------------------------


    Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools

    [​IMG]


    • Drag the setup package onto ComboFix.exe and drop it.

    • Follow the prompts to start ComboFix and when prompted, agree to the End-User License Agreement to install the Microsoft Recovery Console.


      [​IMG]


    • At the next prompt, click 'Yes' to run the full ComboFix scan.

    • When the tool is finished, it will produce a report for you.
    Please post the C:\ComboFix.txt in your next reply.

    I'm in the process of getting the Recovery Console, but I also seem unable to disable CyberDefender, despite being unable to find it on the machine. It's not in program files. I can't start add/remove programs either. I did have it, but I removed it when I couldn't get it to disengage, or rather, I thought I removed it, as I have clearly failed.

    Also, no, it's not a work machine. I live in a rather large house, and we use the router upstairs, and they're rather uppity about lending assistance.

    If you know you have removed it then you can disregard combofix's warning. It doesn't always do a very good job at determining which programs are enabled and which ones aren't.

    "ComboFix has detected the presence of rootkit activity and needs to reboot the machine"

    ok?

    edit: but, yes, the Recovery Console was sucessfully installed. I also ran a full search for CyberDefender and found nothing.
