"rundll error error loading winudu32.rom the specified module cannot be found"
I even have deleted files of internet download manager from registry but it didn't fix da problem

STEP 1: IDENTIFY

The first thing you must do is to identify the specific rundll process. This is not a difficult task; there is a vast online process library in which you can evaluate the validity of the process that is running. When the error dialog box opens make not of the process name. For example if the dialog pops up and shows you the dll error:

Error loading C:WINDOWSsystem32usvdgpo.dll

Visit www.processlibrary.com . Copy and Paste the dll or simply type it into the search box. The results will indicate that the program is a part of trojan spyware.

STEP 2: STOP THE PROCESS
Often you can locate the Run Dll in the exe services. You can open up your services configuration by following instructions below:
1. Open your Start menu.
2. Click Run
3. In the command screen type:services.msc
4. This will bring up the Services Management window. If you drag the mouse to one of the services. It will give you a detailed explanation of the service in question. By right clicking the individual service.
5.Stop the "dll"service immediately.



NOTE: Sometimes the dll process can not be stopped by this method.


STEP 3: LOCATE AND DELETE
You will have to open your Windows Registry File System. This is an extremely delicate process. You may want to use a good registry cleaner This will often fix the dll error in question, eliminate other errors and also speed up your computer. The registry key: HKEY_LOCAL_MACHINE> SOFTWARE>Microsoft>Windows>CurrentVersion>RUN

This action will help you speed up your applications load times considerable. Here is how:

1. Click Start
2. Click Run
3. Type regedit (click Continue in case of UAT)
4. Find this registry key:
HKEY_LOCAL_MACHINE> SOFTWARE>Microsoft>Windows>CurrentVersion>RUN

5. In the right section click:"rusvdgpo" = "%System%undll32.exe %System%usvdgpo.dll, [RANDOM LETTERS]"
6. Delete the value and Restart.
