Windows dll files have errors which causes problems when running Windows

Question

Dear All:

My computer has been giving problems for a long time. It's very slow, sometimes it freezes up and I have to restart many times. I used various Antivirus, Firewall, & Spyware utilities but none of them helped. On Tuesday, March 30, 2010, I posted in the Trend Micro Community and got a response which informed me that something was wrong with some system files. The response is shown below. I am unsure what to do so please help. I am not technical so explain in simple terms. Thanks.

"1. From the MSINFO log, a couple of application faults appear to point to a possible issue with the OS:

 30/03/2010 3:17 AM    Application Error    Faulting application TFService.exe, version 4.10.1.14, time stamp 0x4b4fa1c8, faulting module ntdll.dll

19/03/2010 11:02 PM    Application Error    Faulting application TFService.exe, version 4.10.1.14, time stamp 0x4b4fa1c8, faulting module MSVCR80.dll

The modules highlighted above are critical Windows dll files, and are required for the OS and programs installed in the OS to work properly. I recommend contacting MS about these."

Answer 1

The high-level guidance is to enable full page heap for the executable image, and then run the image under the debugger, with the hope that the additional checks put in place would trigger a fault at the time of corruption, rather than at the time the corruption was encountered (which could be seconds, minutes, hours, days, or longer, after the corruption took place).  The faulting module could then hopefully be identified, and the vendor could be contacted for a fix or other triage.

Answer 2

I agree and since I'm not a Technician then I'm not sure what tools would check for memory corruption.

Answer 3

Hi Mick:

Here is my progress so far. I still have drivers to check.

Drivers

I used Windows Update and have not visited Dell’s website as yet.

Malwarebytes' Anti-Malware

Scan Complete, no threat found.

Avast Free Antivirus

Scan Complete, no threat found.

Vista System File Checker Tool

C:>sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.

Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

Answer 4

If the program is crashing as a result of memory corruption, files such as ntdll.dll and msvcr80.dll can be falsely implicated.  The difficulty lies in determining what component is responsible for the corruption.

Answer 5

·                         Go to your Laptop/Computer Manufacturer's website > Drivers and Downloads Section > Key in your Model number > Look for latest Vista Drivers for it > Download/install them.

Besides using an anti-virus, also scan for Malware/spyware:

http://www.malwarebytes.org/mbam.php

Malwarebytes is as the name says, a Malware Remover!

Download the Free Version from the link above.

Download, install, update and scan once a fortnight..

How to use Malwarebytes after it is installed and Updated:

1. Open Malwarebytes > Click on the Update Tab  across the top> get the latest updates.

2. On the Scanner tab, make sure the the Perform quick scan option is selected and then click on the Scan button to start scanning your computer

3. MBAM will now start scanning your computer for malware. This process can take quite a while.

4. When the scan is finished a message box will appear

5. You should click on the OK button to close the message box and continue with the Malware****removal process.

6. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.

7. A screen displaying all the malware that the program found will be shown

8. You should now click on the Remove Selected button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.

9. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.

10. You can now exit the MBAM program.

Run the Vista System File Checker Tool:  

[http://www.tech-recipes.com/rx/2231/vista_run_system_file_checker/](http://www.tech-recipes.com/rx/2231/vista_run_system_file_checker/)  

1. Open a Command Window in Administrator mode:

\* click
**Start**  

\* click **All Programs**, then
**Accessories**  

\* right click on the **Command Prompt**option,  

\* on the drop down menu which appears, click on the **Run as Administrator**option.

\* If you haven’t disabled User Account Control (and you shouldn’t!) you will be asked for authorisation. Click the Continue button if you are the administrator or insert
 the administrator password.

2. Start the System File Checker

\* In the Command Prompt window, type:
**sfc /scannow**,  

\* press Enter.  

\* You’ll see “the system scan will begin”.

The scan may take some time and windows will repair/replace any corrupt or missing files. You will be asked to insert your Vista DVD if it’s needed.

Close the Command Prompt Window when the job is finished.

One caveat: you need a Windows DVD to enable SFC to make more than minor repairs.

“How to analyze the log file entries that the Microsoft Windows Resource Checker (SFC.exe) program generates in Windows Vista”

If SFC finds serious errors it can not fix, you may have to do a Vista Repair Upgrade Install.

If you do not have a Microsoft Vista DVD, borrow one from a friend.
