बोगुस मेल

I HAVE RECEIVED MAIL FROM MALAYSIA DECLARING ME WINNER OF AN UNBELIEVABLE AMOUNT IN MILLION DOLLERS WITHIN 25 LUCKY WINNERS AMONGST 50000 CUSTOMERS OF ONLINE EMAIL ADDRESSES. I THINK THIS IS A SCAM EMAIL BECAUSE I HAVE NEITHER PARTICIPATED IN ANY CONTEST NOR PURCHASED A SINGLE TICKET. I PROVIDED THEM MY INFORMATION AND NOW I AM IN SUSPENSE AND PLEASE SUGGEST ME THAT WHAT CAN I DO IN FUTURE.
