An email says an update of Outlook Express is essential. It looks official, but WebShield says it's a possible threat. How does one know what to believe?

There's a fake email security alert going around at the moment, warning about KB910721. If you run the attachment, it will infect your PC with a trojan/spyware program. Usually these fakes are easy to spot because of internal errors, but Sophos comments that this one does look plausible: "the spelling and grammar are surprisingly correct, for malware authors".
However, the fact is that Microsoft will never email you an update: it wants you either to turn on Auto Updates or visit Microsoft's web site for security patches. Also, Outlook Express became obsolete about three years ago, when it was replaced by Windows Live Mail.
