When my wife opens outlook it does not go to the inbox, but shows a large picture of a child and asks to signe in.

When signed in I go to Tools>internet options>use current & Outlook opens in Inbox for this session, & every time I restart the PC the same thing happens.

My wife is worried about that foto that it may be the work of pedofiles.                     

How can we get rid of it please?                   ...................nick

PS she was on Hotmail for years before the ruddy MS changed it. She has IE & Vista.
