i think my yahoo account has been hacked. Last night my oh received an email from me that I never sent with a link on it which I told him not to open. I looked on my 2 yahoo accounts I have and mainly on one I saw that there were lots of maile demon failure notices that had come back to me and some emails from ebay, emma bridgewater etc saying that I had sent and email and they will get back to me. I am concerned. Do I change my password or do I set up a new email account. A pain if a new one as my cv has my email addy on it and needed to for work by people who already have it. Why do people do this and why?
