Recently there is a warning being mailed around by the police about a Power Point Presentation named "Life is beautiful".
If you open it you get the text "It is too late now, your life is no longer beautiful", all your files disappear from your computer and the person having sent the mail has full access to all your files, passwords and mails.

It is said there is no program able to protect you from this. The nick of the creator is "Life Owner".
