I think I am having similar issue, but honestly most of this is Greek to me, so not sure. On advice from a computer expert, I recently installed Avast (free version). It seemed to be fine, it installs updates automatically. For 2 days I have not been able to access my AOL email thru AOL's Desktop version. I spent over an hour on phone with AOL tech support, they said Desktop version uses same protocol as Outlook (where as AOL 9.5 does not and that is working fine for me) I prefer AOL Desktop version. It keeps giving me "Cannot Connect to IMAP Server" error message, then "Connect Error 100160". My husband's laptop has Norton and is able to access AOL Desktop just fine. So is my problem because of AVAST update? It shows I have Avast 5.0.418. Please help. I am not a techno guru and am totally lost.
