I am getting a troublesome screen popup after I click Done on the last screen setting up my AOL account in this new Thunderbird. Does anyone know if this is a malware taking over to get my login credentials to AOL? Why would this be popping up when maybe it should link to AOL login directly to check my login credentials? What is this "Castlemedia" link deal to finish my Thunderbird to set up? I added the full hyperlink that shows up at the top of the AOL LOGIN screen for you all to view.

Thanks for any help...from the support group here. Eric S.
