    It depends upon the source. You should ALWAYS scan then with your AV first, even if the file is from a relative. Some virii deceive by having the extension AND having a .exe, hoping you wont see the latter. For instance, .jpg might sound harmless. But what about .jpg.exe?

    Exactly.

    I believe a Macro virus can be hidden within a .doc

    PDF had a virus called "Peachy"

    Viruses can be hidden in most formats so you should always consider the source of the file specially if it comes from email with a couple of 100's of CC's.
