While reading and sending AOL e-mail, I get a warning which says, "Your connection to mail.aol.com is encrypted with obsolete cryotography.  However, this page included other resources which  are not secure.  These resources can be viewed by others while in transit, and can be modified by an attacker to change the look of the page.  The connection uses TLS 1.2.  The connection is encrypted using AES_256_CBC with SHA1 for message authentication and RSA as the key exchange mechanism."

What can I do to ensure my e-mails are not being read and altered by a third party?
Thanks for your help.
