NOTES:

When executed, this virus stores its codes in the Ring 0 Windows memory area to load itself in memory. It alters the PE file header so that the virus codes are accessed every time an infected file is executed.

If the target file contains a PE section with the name .reloc, it overwrites the section with its codes and deletes relocation information in the PE header. Otherwise, it adds the section, Padania, to store its virus codes.
