Hi and welcome to Avast,
Technical’s already, as usual, answered your main question in his inimitable style. I use Eudora myself – a few versions of avast! back, there was a bug that interfered with outgoing Eudora mail, but that was quickly fixed quite nicely.
I’m inclined to agree with you about OE – I don’t know if it’s still true, but there used to be one heckuva lot of viruses in-the-wild which specifically targetted OE and its files.
(Edited – forgetting in my old age which forum I’m currently in.
