change your password otherwise they will continue to login in to your account and send message to your contact list.
Do not do what I did, I erased all of my contacts.
Let everone on your contact list know that your email has been hacked and expect to get frivolous emails about some kind of buisness opporunity.
But the emails are not from you.
Once you click on the frivoulous email info button they hack into their emails and send out similar business email messages hoping that everyone will open them.
So... I have been a victim of such a scam, let everyone you know not to click on their links or else they will automatically have access to thier contact list making them think its you that sent that email mesage.
