Verizon.net Email - Yahoo says change password, but sends me to change my Verizon.com password

[Stevenet1]

Apparently my verizon.net email was used to send spam. Yahoo has blocked my account and wants me to change my password. The link takes me to change my password on Verizon.com, not the email. I already know this does not change the Yahoo email password because this happened to my wife's account about two years ago and it still doesn't work right (she has a work-around to get to her email).

I do not want to change my Verizon.com password.

I've seen othere posts that this ahs been a problem for a long time. What is the anwser?
