I am facing a certain problem. I am trying to delete a certain file programmatically that resides in the system32 folder (malicious file). When i try to delete it using the kill statement an error message shows that says Access Denied as the file is being used by another process. When i searched i found out the that winlogon.exe uses this executable. How can i remove this handle programmatically. Any ideas and suggestions would be very helpful.

If you are doing test work, create a VM and to your tests in that which you can rollback easily instead of corrupting your system.
