My father has an XP computer he got from his work last year when they switched to Win 7. The company IT man deleted everything work related from the computer before it was given to him, including the e-mail account of the office personnel that was using it. Here is the problem and it has happened twice...the computer is automatically reverting to the deleted e-mail account. The first time, it sent out over three months worth of e-mails one night, while it was not being used (dad does not turn his computer off). This time, it sent out a months worth of e-mails. In both instances, the e-mail showed to be from the employee whose account was deleted.
My first question is, any ideas about why it is doing this? My second is, what do I do about it?
