VBS.Tam.A

VBS.Tam.A is a worm that is only able to run on French Windows operating systems. The worm uses a known security bug in Microsoft Outlook Express called Scriplet . Typelib. Wscript.KakWorm was the first worm to use this security hole.

Microsoft has since patched this security hole. The patch is available on the Microsoft Web site. If you have a patched version of Outlook Express, the worm will not work.
