Split from this thread.

Yesterday using my email account I went to contacts and instead of my list

of names there was only an entirely new contact called echo123. Something

to do with skype. I don't have a camera on my pc, so I don't skype.

I couldn't delete it nor move it into my own rubbish file.  Most seriously I have

lost all my contacts.  I carried out a restore to about a week ago and rebooted, but this nonsense persists.  It is nothing that I have done.  I suspect an outside

hacker.
