Membuat Virus Sederhana

kita akan membuat virus yang sederhana menggunakan Notepad. Virus ini akan membuat dirinya menyebar ke removable disc dengan AutoRun sehingga komputer lain yang tercolok flash disc terinfeksi akan langsung menjadi korban tanpa menungu User menjalankan infector-nya. Virus ini saya beri nama “Kalong.VBS”. Sekarang buka Notepad-nya. Copy kode berikut :

‘//–Awal dari kode, set agar ketika terjadi Error dibiarkan dan kemudian lanjutkan kegiatan virus–// on error resume next

Save code di Notepad dengan cara FILE > SAVE. Lalu di save as type pilih “All Files (*.*). Simpan dengan nama : k4l0n6.dll.vbs. Sebenarnya gak usah pake *.dll juga gak apa-apa tapi usaha agar tidak mencurigakan aja.
He..he…Virus Worm ini memang bukan murni dari pemikiran saya sendiri karena meniru kode-nya virus Rangga-Zay. Tapi yang ini lebih bagus karena tidak terdeteksi pakai PCMAV RC15, CLAMAV, dan AVAST. Itung-itung ini buat Anda tahu kalau membuat virus/worm tidak perlu membeli software bajakan. Pakai Notepad (dari Windows Original) juga bisa.
