Still problamatic

Hello everyone!,
I guess I was too quick to report I was connected again...Wrong! My e-mail is still not working properly. My son is communicating with Yahoo to clarify this but until then I am unable to answer your much appreciated comments.
Some of you have asked how the "Hacker" could do this and how can you protect yourself from this happening? Well I have been informed there is nothing we can do to prevent this,. There are people out there who do not quilt, sew, bake or even think of the well being of others and they hack until they infiltrate someone's e-mail. Since this has happened to me I have heard of many people who experienced the same thing .. even the same letter. Yahoo froze my account so it shot down the possibility of anyone logging on in my yahoo mail until I changed my password. My contact list was deleted for that same reason, therefore I do not have any addresses in my address book anymore. I am very happy that I never sent my visa card number or any financial account numbers from my e-mail. When ordering on line make sure you go through the secure sites of the company you are ordering from and not your e-mail. I am hoping I will be able to contact with you individually soon.
