Thanks for your informative answer.
When you refer to opening and closing an old document asking to be saved, I think that also applies to any document that I open that I know does not have macros. If there was an infection these docs would ask to be saved.
Is Word itself infected and it infects all documents or does an infected document have to be open to infect other documents?
Can Word macros infect Excel files if they are all open at the same time?
I have macro protection turned on, but I never see the macro warning.
I asked this question because an I had two emails open with Word attachments, also open, when Word gave me a strange error message, (something like: Word has encountered an error and will delete the document.) All the text in one email was deleted. I've tried looking at macros in Word and anything I can think of, but there appears to only be the prepackaged macros that come with Word. There is almost nothing on the internet that I could find. MS calls the macro warning -> macro protection, which it isn't, and that's the end of any reference to Mac Word viruses.
