Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.
What precisely are you trying to do with the McAfee Protection software (or, subscription) in question? obviously a password ***** ***** but I need to know, before I advise you, what attempt is bringing up the password ***** and whether you are trying online in a web browser, or offline (essentially) on your computer.
(Generally speaking, if you have access to your late husband's email account, you may be able to get the information you need.)
