Microsoft will *NOT* send you a critical update.

Most of you reading this post already know this, but Microsoft will not send you a personal email with a critical update. I've been flooded with about 20 of these today. They are very authentic looking -- they resemble the Microsoft home page, same layout, fonts, trademark and copyright notices, the works. But the attachment is just another virus/worm.

Let friends/relatives who may not be as technical as you know this is out there. Don't let them get bit. More than likely, you'll have to clean up the mess! :)
