yahoo lottery — HI..

Respected Sir,

I got a email saying I had won a YAHOO-MSN LOTTERY of worth 780, 000.00GBP.They asked my personal information and without thinking I had provided all my information.Then they sent me batch num, winning num and reference num, and told me to contact [protected]@live.com to get cheque and they also given their email id as [protected]@live.co.uk.But without moving further i searched in google and found that other 2 persons also got same email as me, everything including winniner, batch n ref num was same and then i confirmed its a fraud..But, i had provided all my info, whether will it harm me?so what to do further?waiting for ur reply..
