My Yahoo Mail is being redirected to Verizon mail

I am guessing that I have been hacked but now when I click on my Yahoo mail I open up Verizon mail log on. I do have Verizon as my phone provider and this redirect is happening on my phone and both PCs; all have AVG installed on them. Verizon tech support was no help. After wasting time with Verizon tech support I logged in on the Verizon site to see what happens and it went back to my Yahoo mail. I'm sure someone somewhere now has access to my emails and potentially the rest of my PC.

Any ideas?
