How to Replace Rundll32

1. Run a scan with your anti-virus software or run a registry cleaner on your computer to get rid of the virus files in the computer's registry. To run the scan with your anti-virus software, double-click the program icon in the taskbar of your computer and click on the 'Scan' or 'Clean Now' option. To use a registry cleaner, download a free cleaner, such as Glary Registry Cleaner or RegToy, online, install and launch the cleaner, and click the 'Scan' or 'Clean' button.
2. Delete the files that appear in the list of corrupted files found by the anti-virus software or registry cleaner. Most anti-virus software and registry cleaners provide a delete option right in the program. Once the files have been deleted, restart your computer to remove them completely.
3. Stop the dll service from running on your computer once your computer reboots. To stop the service, click the 'Start' orb, go to 'Accessories,' choose 'Run' and type 'service.msc' in the 'Run' box. Right-click 'dll' in the 'Services Management' window that appears and choose 'Stop' from the menu options.
4. Open the computer's registry editor by going back to 'Start>Accessories>run' and typing 'regedit' into the box. Once in the registry, click the 'HKEY_LOCAL_MACHINE' folder, 'SOFTWARE,' 'Microsoft,' 'Windows,' 'CurrentVersion' and 'Run.'
5. Right-click the key labeled 'rusvdgpo' in the right-hand pane of the registry editor. Choose 'Modify.' In the box that appears, delete the text next to 'Value' and click 'OK.'
6. Restart your computer. Windows automatically searches and replaces any missing system dll files, including the Rundll32 file.
