Yahoo users who have received deactivation emails like the one below, which claim that their accounts need to be updated or else they will be deactivated, should delete the emails and should not follow the instructions in them. This is because the fake emails are phishing scams sent by cybercriminals and NOT by Yahoo, to trick Yahoo users into clicking on the link in the fake and malicious email message that goes to a phishing website that steals Yahoo email account username and password.
