How to Remove Rundll32

1. Navigate to the Rundll32.exe file. It will be located in the C:\Windows\System32\ folder.
2. Right click the file and select 'Copy.' Rename the Rundll32 file to something that you will remember. You want to make this copy because if something goes wrong after you remove the file, you will have a backup available.
3. Attempt to delete the file by selecting it and hitting 'Delete.' You might be prompted by a window asking if you are sure you want to remove the file. If so, click 'Yes.' However, this most likely will not happen because there are 'locks' on the file that may keep it from being opened or removed.
4. Use a software program to remove locks placed on programs and files, such as Unlocker, a freeware program that can be downloaded from a link provided in the Resources section.
5. Click Unlocker to download the file, then open the desktop icon. Follow the installation prompts to complete the setup.
6. Right click the Rundll32.exe file, which will bring up a drop-down menu. Select 'Unlocker.' This will launch a new window that showcases all the locks placed on the file, keeping it from being removed.
7. Select the 'Unlock All' button on the window, then choose 'Quit.' The locks will now be removed from the file. Click Rundll32.exe for the last time, and hit the 'Delete' button. You will now be asked if you are sure you want to remove this file. Click 'Yes,' and the file will be removed.
