Never never never open anything from a stranger.

Yes, it appears to be junk mail.
Never never never open anything from a stranger.
Lots of people who are in business, or have published their email as a contact address, get real mail from strangers. I don't think most people can function under those rules.
BTW there is nothing magically safe about 'knowing' the person who sent you the email. More often than not, a virus WILL come from someone you know, someone who has you in their address book. It isn't personal, that's just how they are spread. That person may or may not be the name that appears as the sender. The smart way is to keep your virus software up to date, and be smart about attachments. don't open ones that you wouldn't expect, and not files executable type files. If you don't know what it is, ask the sender. Just be prudent.

Her virus software should have already been running, and have scanned it coming in.
