My sharp wife did a mindless act after opening her web mail account by opening an email that appeared to be from her niece and clicking on a link in the text. What she got after that was suspicious, and she went back to check things out. There was a permutation in the supposed email address of the niece; the other clue was the strange subject, and even the text of the message was off beat. Lots of manifestations of evil, but she allowed herself to get ahead of her ski tips.
Results: the https in the address window has a red, diagonal line across it. After she signed out of her account, I logged into her account from a different computer, and I experienced no diagonal line.
In a chat with Earthlink staff where she has her email account, she was advised to do a full AV scan, and also try resetting her Chrome browser to Chrome's default configuration. Neither of these actions eliminated the red, diagonal line over the https in the browser's address window. In the chat with Earthlink tech support, a temporary password was issued in order to log on. (The traditional password had worked, but it was advised to change it.) The newly issued password was used to log on line at the Earthlink server which then an even newer, more sophisticated password was established.
Her computer is a relatively new Lenovo laptop with windows 8.1. Both Windows Defender using full scan and Malwarebytes Premium came up with negative findings in a search. A call was made to the niece, a bright CPA who acknowledged her email address book had been hijacked.
Am I infected, or is this just a hit and run with the address book ? What is the meaning of the red, diagonal line over the https ? ... occurring only on her Lenovo and not a different computer after logging in. Should contacts on the address book be notified to be leery of receiving email from my wife until they get a follow up that the coast is clear once again. Please assist in restoring the security of the email address account.
