Skype.exe - Entry Point Not Found

I am getting following error message when I open Skype.

"The procedure entry point NtAlpcSendWaitReceivePort could not be located in the dynamic link library ntdll.dll"

I tried to fix it in the following ways - 

1. Uninstalling and re-installing Skype didn't help.

2. Since I read this is something related to KIES, I uninstalled KIES, Samsung USB driver for Mobile Phones, Samsung Symbian USB Download Driver and Samsung Mobile Modem Driver Set and then opened Skype - Problem did persist even after that.

3. I re-installed KIES because I thought this has nothing to do with it.

4. I didn't intend to rename avrt.dll since I thought it would cause any faults in KIES.

5. Fully scanned (Vulnerability Scan, Critical Area Scan and Full Scan) my PC with KIS 2012. I got nothing wrong.

6. Tried "sfc /scannow" and followed the instructions. Even that didn't help me.

7. Used Combo Fix to find if there's any Malware infection. No use!

8. And at last, renamed avrt.dll as avrt.dlx.

That worked! 

9. Then I tried using KIES. It didn't come up with any errors as far as I used it.

Now, what I want to know, 

"Which application uses avrt.dll?"

"Where will I get stuck since I renamed it??" 

Please help me to get rid of this.

Thanks in advance.


avrt.dll is a system file of Windows.

Renaming the file should not cause any issue to the performance of the computer.

However, if in case you face any issue I would suggest you to copy the file from another healthy Windows 7 computer.
