To remove the program that will launch the virus in the registry you have to know how to edit your registry setting. Editing the registry is very easy as long as you know where you are going inside the registry. Just be careful to edit your setting because misediting the registry will render your computer inoperable.

9. Click RunOnce delete all the entries here also

After deleting the entries in the HKEY_CURRENT_USER delete the entries located in the HKEY_LOCAL_MACHINE

10. Double Click the HKEY_LOCAL_MACHINE
11. Do Step 4 to 9
12. Close the registry editor.

After editing the registry delete the programs in the Startup folder
