You receive an email message that appears to be from Microsoft. The email says you were randomly selected as a winner of the "2013 Microsoft Edinburgh Products Anniversary Award." There's an attachment, which the message claims is a letter of congratulations. When you click on the file, you find that it isn't a congratulatory note after all. It's really malware that will download to your computer. Typically, these viruses phish for personal and banking information on your machine. Be wary of unexpected emails that contain links or attachments: As always, do not click on links or open the files in unfamiliar emails.
