Microsoft recently informed me my Inbox had been hacked. Mails were being sent to everybody in my present and past address books. Even dead people, which was distressing. Microsoft took me through the procedure to set up a new password and I ran a Microsoft security scan and also an AVG scan. Both gave me a clean bill of health. Since then I've been unable to send an E-mail with an attachment. The mails are aborted during the attachment download. The reason given is one of IE stopped working, Live.com stopped working or there is a problem with Outlook. Help please!
