I don't see anything free at this web address. Thanks for your suggestion but it seems more involved than I want to get into. I foresee more problems if I don't do everything correctly. I don't need to extract attachments, I just want to open it and then either save it or delete it. I thought that others may have experienced the same thing and had an easy fix. I can't understand why it has happened out of the blue. I am running the same anti-virus--Norton. I found that I get this message intemittently when I click on the attachment to open it and I also notice that it intermittently happens when I click on it to "Save as". I guess I will have to live with it for now.
