Hi all, Lst night, out of the blue, I discovered I am unable to send either AOL or Yahoo emails with pdf attachments on my Imac. This never happened before and I am wondering if I have a virus? How would I tell? My IMAC was purchased new Dec. 2009. When I send AOL email with pdf attachments I get a "we encountered a technical issue" message. When I save the draft email the attachments disappear. A few times the email was sent wthout the attachments. In Yahoo, it loads forever and then stops. Since I sometimes work from home this is beyond frustrating and bewildering. I appreciate any help!
