I don't have a gmail account but gmail shows up on my history of sites visited every day how does this happen?

does anyone else use your computer at all? Maybe THEY have a Gmail account.





Also if you use any Google products you technically have a gmail account.





Such as "Blogspot" or something like that.

If anyone else is using that computer maybe they have a gmail account or if you have something that you downloaded someting on your computer and you had to make an account for gmail.
