BEWARE! – FAKE! Update for Microsoft Outlook / Outlook Express (KB910721)

I just got this in my inbox – it seems to be pretty malicious as the URL really point to the following domain

I have no idea what malice this may cause, and I am not about to find out.

UPDATE – I have received this a number of times now with multiple subject lines. Here they are:

• Microsoft has released an update for Microsoft Outlook
• Microsoft Outlook Critical Update
• Update for Microsoft Outlook
• Install Critical Update for Microsoft Outlook
