A hacker and VERY SICK 'man' from Aasco, Puerto Rico, who seemed to be such a good and spiritual person, got into my computer, changed my Google account password,and also is able to get EVERY e-mail I receive on my Yahoo account.Could you please tell me what to do to get my Google account back AND to ERASE HIM COMPLETELY from my computer? I have also discovered a VERY OBSCURE side of him.
I also want to know IF I can keep all my actual important Yahoo e-mails that I have saved in five years in the event of having to get A NEW Yahoo account.
I thank you ALL for your time and guidance.
Tuttoamore.

Have you tried the password recovery tools on each service?

They usually ask you a secret question or send an email to your back up email address.

You, of course, then change your passwords, see what he sent out in your name and correct anything that needs correcting.

You change the password of your computer and run a commercial antivirus and anti spam software search on your computer to ensure he didn't install anything malicious.
