See below on comments of this criminal?

This is the second time to get answers - first one sent this am 5/24/11 and was answered by 'Lou' - his answer not appears to be complete - stated basically change my password. Hacker somehow (I'm not into Facebook and Sophos anti-virus which checks almost every minute has not documented any viruses) sent a message out that myself was in UK asking for $. This sounds alot like a criminal who did the same thing to my sister-in-law a few months ago - situation almost identical - and yes she also has Yahoo email. In addition I'm a Yahoo stockholder so maybe my Yahoo relationship will be severed in (2) areas. Due to this hacker, all of my past input emails have been deleted - would like them back - as well as past email contacts. My preference is to talk over the phone with Yahoo as this back-and-forth internet is not helping me including what can be done to avoid this in the future.
