How to Stop a Rundll Error From Wreaking Havoc on Your Computer

1. Scan your computer with an anti-virus program. Many free programs available include AVG Anti-virus and Avira. Many dll errors are caused by virus or spyware programs that are corrupting your registry; scan the system (via a simple step-by-step process) and delete any hazardous files that are flagged in order to stop the corruption.
2. Download and run a registry cleaner. A number of free programs available online can clean your registry and correct errors. Abexo Registry Cleaner and Eusing Registry Cleaner are useful free programs. Just click on the 'Scan' button and select the drive you want to scan, and they will correct the registry errors in that drive.
3. Remove any programs from your computer that you do not use. The more programs on your system that are accessing the dll files, the more likely errors will occur. Access your Control Panel through the Start menu and select 'Add or Remove Programs.' A list will populate showing your programs. Click on a program from the list to select it and then click on the 'Remove' button on the left of the window.
