Hi, I am not sure where to post this question. I am brand new - please feel free to redirect me to proper forum I have a MacBook Pro, and use the mac mail which has my 2 email accounts. i was in my inbox and used the search (upper right hand) to find email address for someone I was going to email. A yahoo address of someone I know but have NEVER emailed to nor have I ever received an email from, came up when i pressed some letters on my keyboard. this person is extremely computer savvy. does this mean I have been hacked into? Thank
