hackers has being sending out links to peoples mail, once you click on that link they will have access to your email and do anything they want to do with your email: especially your password and username of other things you are doing online.
go to your sent items you will see that your mail has being used to send message to your friends, all you need to do just reply them that they should login to their mail and change their password.

Great information, had a strange link sent in by my known corporate email adress. Called d org but no such was sent by them though the message is in their sent folder but was not sent by them nor d content related to any business i do with them. Pls always verify before clickn on strange links.

if u click on any link and refresh anything that has password and it request for password again then something is fishing,quickly close that link and delete all cookies before proceeding.the best way is to password your system,is always the best.
