get rid of verizon redirection at logout

Since I can no longer easily select my associated e-mail accounts due to recent changes due to security issues, I now have to logout. However the logout redirects to Verizon (an issue for years now), though I have never used Verizon (just use Verizon as carrier who somehow asserted itself on me when I installed the Verizon interface when I installed the Verizon comm package). I want to get rid of the top bar that has the Verizon redirection and logo on it (one of my associated accounts has the same bar and problem, the other 2 do not) but cannot find out how to do so.
