I have an application using an ocx file, after executing the application, when I did right click on the ocx file, I found two new attributes( Everyone and Anonymous ) is added in the properties of ocx file that prevent ocx file from deleting( properties -> security -> Group or username )
How can I remove these attributes programatically in order to delete the ocx file or is there any way to prevent creating these attributes during the executing application?

The attributes are inherited from the folder in which the .ocx is stored. If it is a secured folder such as windows/system32/ then the files in that folder will have the same security attributes applied.

This means to remove the file the application needs to be executed by an account or group with the necessary rights to remove the .ocx.

The .ocx cannot be removed if it is in use.

[Update]
You may need to unregister the ocx first. MSDN link:
