Recently someone asked me if I sent them an e-mail, I told them no but they insisted they got a message from me.
They showed it to me and it was from my email address, and my name on it. It said: ''How are you?" - and there was a referral link below it (don't remember what site it's from, I'll ask again later to be sure)
I logged into my account and checked the Sent folder and there wasn't anything in it.
Checked the recent activity log and found that my account was accessed from Chile 3 days ago.
I already changed my password, is there anything else I need to do to be sure my account is safe?
