What is a rundll error?

Rundll.exe files are systems process directly related to your computer's Windows Registry. All Dll files are a part of vast library that contains code and data that is shared by many programs. This helps to produce speed and memory efficiency in your operating system by reusing the same code or file to run many functions by various programs. An error occurs when program aren't allowed to access this code.

Why do you have Rundll Errors?

Windows uses rundll files to load programs, files and applications. If the dll file is missing or corrupted, any application using that file cannot be loaded. This will produce a rundll error. The reason why the file has gone missing is often linked to spyware or a virus. This kind of malware often tries to hijack the files being shared by the rundll file. The other programs sharing the file then do not operate efficiently or wont load at all.


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, it displays the the process name. For example if the dialog pops up and shows you the dll error:


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.


You will have to open your Windows Registry File System. This is an extremely delicate process. 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
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.


rundll.exe is an essential system process. However, it has a large back door vulnerability which makes it prone to malicious purposes by an attacker allowing access to your computer from remote locations, stealing passwords, Internet banking and personal data.

Trojans are usually use this method of attack to share a process that invites other malware either more trojans or other forms of spyware. The best defense is to keep your security software up to date and account for the rundll processes on your computer.



Above informations is much to explain and resolve the issue.

Since this is a tedious process for beginner, it is better to create a new user account and delete the error causing user account.

Because it not only fixes the issues, it will have new user settings and program files necessary for user account.

Once you are into new user account you can scan by using a program which sync with server and check for virus/malware/spyware.
