I did look at your specific question, and I specifically responded to it.
I understand the ins and outs of googles device tracking, security measures, apis, account security, device history, etc.
On one hand we could just change your password ***** security info on google, and could call it a day.
But, what we dont know until we DIG into your google account settings is if at some point your account was actually accessed.. If it was, that account can be used to spread files and programs to your devices, and if you have google set to save passwords, all yoru passwords could be at risk. I am not an alarmist, this could be a simple error.
I offered you a screen share at a reduced cost because this will make it easier and less time consuming for both of us.
If you prefer written support, thats fine too.
Just let me know how you want to get started.
