can i trust this email?

[Aceospades]

I got an email today that looks like it’s from Microsoft saying that I need to open the attachment. There’s no text in the email, just the attachment titled “Installer.exe (21 KB)”. I’ve cut and pasted the headers to the email. I’m more then a little suspishious of this email. Any one have any idea what the attachment could be?

NO! Do not open that attachment! If you really want to know why Microsoft sent you something, go ahead and mail them and ask. Microsoft would never send you an email; they would just release a patch for whatever needed fixing (or breaking).

Emails of this nature are always, invariably, and without exceptions, scams, a virus, or malware.

Microsoft does not deliver software updates via e-mail (http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/policy/swdist.asp)

Tried briefly to analyze the headers there, but why bother... if you wanna know what it is, check out the front page of http://www.stopspam.org/ at the moment.

As with most unsolicited e-mail, take a moment to realize that nobody wants you to move 500 million in gold out of Namibia, that herbal concoction isn't gonna give you a 12" schlong, and if Microsoft wants your machine to do something, hell, it's already running their software! So bin that e-mail and forget it. :)
