Rundll32.exe error 0xC0000005?

By samm1
Jun 22, 2008
  1. Hey guys,

    Recently whenever i log into my computer i get several "userinit.exe - the application failed to initialise properly (0xC0000005)" error messages and the desktop doesn't load. After i run explorer through task manager i get several "rundll32.exe - the application failed to initialise properly (0xC0000005)" messages.

    Yesterday I did system recovery to a few days back and on reboot the error messages went away. But this morning they came back...

    That is an old version. Please uninstall through add/remove programs and get the newer version of hijackthis

    Highjackthis Instructions
    • Make sure you have the LATEST version of HJT (currently v2.0.0.2) it can be downloaded from HERE
    • Run the HijackThis Installer and it will automatically place HJT in C:\Program Files\TrendMicro\HijackThis\HijackThis.exe. Please don't change the directory.
    • After installing, the program launches automatically, select Scan now and save a log
    • After the scan is complete please attach your log onto the forums using the paper clip icon above your reply.

    Okay, i installed AVG last night and did a full computer scan that found 22 "infections". It took about 3 hours and this morning when i accepted the reboot message the error didn't come up. I still think i have more viruses so i posted the HijackThis log anyway.

    Thanks for your help.

    Hey,

    I couldn't find McAfee SecurityCenter on All Programs however i ran MCPR and it looked like it worked. Also after the reboot from the Hijackthis entries i received a RUNDLL ERROR message saying "Error loading C:\WINDOWS\system32\xdtyasta.dll The specified module could not be found." But i think this is normal?

    I have attached both the log files and just want to say thank you for your help! My computer is running much smoother now and acctually starts up correctly!

    Good work.

    Try uninstalling Mcafee framework.

    I also need to know did you install vista them? and did you install a Longhorn clock?


    Combofix
    • Download Combofix to your desktop.
    • Double click combofix.exe & follow the prompts.
    • A window will open with a warning.
    • 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. Combofix is a very powerful tool so please do NOT do anything without instruction

    Combofix will automatically save the log file to C:\combofix.txt

    Oh My God... More malware!

    There is no sign of any Mcafee products in my Add or Remove Program List because i think i have already uninstalled them before. Also I am running Windows XP but i installed a vista Mr X's transformation pack a long time ago. I think i uninstalled it the day after but there are still traces of it on my computer.

    And... do you know why the computer time had to be changed in the combofix scan, just seemed strange.

    Thank You.

    Run CFScript

    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)
    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 together with a fresh HJT log.

    Uhm.. I did as you said but on the combofix console before reboot it said "The specified file was not found" and on reboot windows started normally (No log or console like last time) and came with the "Windows has recovered from a serious error" message. The log was not on my C drive and the CFScript is not on my desktop anymore.

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

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

    Run me a fresh Hijackthis log

    Oops. I just changed CFScript.txt to just CFScript and tried it again. It worked and here are both logs.

    How is your computer running? It just shows a few stragglers -

    a little warning - **P2P programs = Please note that as long as you are using any form of Peer-to-Peer networking and downloading files from non-documented sources, you can expect infestations of malware to occur.
    Once upon a time, P2P file sharing was fairly safe. That is no longer true. You may continue to use P2P sharing at your own risk; however, please keep in mind that this practice may be the source of your current malware infestation. see http://spywarewarrior.com/viewtopic.php?t=26216

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

    I would uninstall WinZix through add/remove programs

    Then navigate to and delete
    E:\Program Files\WinZix

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

    I would also clear private data through firefox - tools -> options

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

    Now we need to secure the work we have done.

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

    * The above procedure will:
    * Delete the following:
    * ComboFix and its associated files and folders.
    * Reset the clock settings.
    * Hide file extensions, if required.
    * Hide System/Hidden files, if required.
    * Set a new, clean Restore Point.

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

    OTCleanit! by Oldtimer
    • Download OTCleanIt
    • Click the CleanUp! button.
      • It will go thorugh the list and remove all of the tools it finds and then delete itself (requiring a reboot).

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

    Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:

    1. Set correct settings for files
      • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
      • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
      • If unchecked please check Hide protected operating system files (Recommended)
      • If necessary check "Display content of system folders"
      • If necessary Uncheck Hide file extensions for known file types.
      • Click OK

      clear system restore points

      • This is a good time to clear your existing system restore points and establish a new clean restore point:
        • Go to Start > All Programs > Accessories > System Tools > System Restore
        • Select Create a restore point, and Ok it.
        • Next, go to Start > Run and type in cleanmgr
        • Select the More options tab
        • Choose the option to clean up system restore and OK it.
        This will remove all restore points except the new one you just created.

    2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
      1. From within Internet Explorer click on the Tools menu and then click on Options.
      2. Click once on the Security tab
      3. Click once on the Internet icon so it becomes highlighted.
      4. Click once on the Custom Level button.
        • Change the Download signed ActiveX controls to Prompt
        • Change the Download unsigned ActiveX controls to Disable
        • Change the Initialize and script ActiveX controls not marked as safe to Disable
        • Change the Installation of desktop items to Prompt
        • Change the Launching programs and files in an IFRAME to Prompt
        • Change the Navigate sub-frames across different domains to Prompt
        • When all these settings have been made, click on the OK button.
        • If it prompts you as to whether or not you want to save the settings, press the Yes button.
      5. Next press the Apply button and then the OK to exit the Internet Properties page.
    3. Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

      See this link for a listing of some online & their stand-alone antivirus programs:

      Virus, Spyware, and Malware Protection and Removal Resources

    4. Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

    5. Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

      For a tutorial on Firewalls and a listing of some available ones see the link below:

      Understanding and Using Firewalls

    6. Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.This is done in Vista through control panel -> windows updates.

    7. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

      A tutorial on installing & using this product can be found here:

      Using SpywareBlaster to protect your computer from Spyware and Malware

    8. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
    Follow this list and your potential for being infected again will reduce dramatically.

    here are some additional utilities that will enhance your safety

    • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
    • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
    • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
    • Winpatrol <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
      Using Winpatrol to protect your computer from malicious software

    Anybody with the same problem - It is too difficult to help multiple people in one thread as it becomes confusing. Here is what you should do.

    Please have a read here-> Is your system infected? Read this before Cleaning or Formatting

    If you decide to clean your system please follow these Viruses/Spyware/Malware, preliminary removal instructions and post back in your own thread with the requested logs. There should be at least 3.

    You can make your own thread by clicking "new thread" from HERE and enter my name in the subject - I will check them as I see them

    What I need to help you:
    1)MBAM log
    2)SAS log
    3)Hijackthis log (last step)
