End
End Sub
5.setelah itu klik file -> MakeProject.Exe-> taruh difile yang tidak ada data lainnya misalnya di newfolder yang kosong agar kalau dijalankan tidak menyebar cepat.
nah Itu lah cara membuat virus sederhana mohon jangan digunakan untuk kejahatan,saya membuat ini 6.agar anda mengetahui bagaimana struktur virus yang sebenarnya.(^_^).ingat jangan digunakan untuk keusilan karena belum ada antivirnya
