When you open an email, the "header" section just above the message shows who the message is from and what attachments they sent you. The names of the attachments are links you can click to either open and view, or download and save to your computer. For example, if someone attached a wedding photo to their message, you'll see something in the header section like 'WildWedding.jpg'.

If you click an attachment, a window will open telling you if a virus threat was detected in the attachment. If no virus threat is detected, you can choose to click either the "Download Attachment" button or "Cancel."

Click the "Download Attachment" button. Another window opens, asking you if you would prefer to open or save this file. Opening it lets you view the file without saving it to your computer; saving it puts it on your computer's hard drive. You can also click "Cancel" if you'd like to exit this window.
