Ground Rule: If you do not need an attachment, do not click on it, or open it.
- Email Worms are sent to your addresses by spoofing (or faking) the "From" address. This means that the email may look like it came from someone that you know. However, do not open the attachment even if this is from a known e-mail.
- Below is a list of file types that should be considered suspicious when an unintended e-mail arrives:
