Thanks for answering again. I appreciate the help. I will go thru your questions in order.
I have checked and my profile is the only one set up on Chrome.
My mom uses her phone for email and facebook. She's never used my laptop. I don't live with my mom. I have only recently stayed at her house after she had a surgery. And she has her own laptop and she rarely uses it.
No, nothing else could have set up another profile. I am very familiar with computers, operating systems, email, pop ups, installation of programs and that some have additional programs they have checked (like some of piriform's add on bloatware, not being a B, I just don't know how else to put it ) and I am always careful about dismissing anything. I always read any notifications.
I have gone thru every possible setting in Chrome and there is nothing I can find that would have another person and my mom's user name to be added.
Windows has recently had an update. I know sometimes after updates the settings are reset to default setting. I don't know if that is a glitch or maybe it's on purpose. But that is my next target to look at.
Let me know if you have any other ideas please. And thanks again!
