I have evidence that someone has been accessing my Google account since I started to login to use a variety of services.  I did not have this problem when I was using my Google account exclusively for GMail.I also try not to accept the keep me sign in option, but it remains enabled no matter how often I change my password.  I feel I have no privacy at all I want to go back to using only GMail.How do I do this without seeing the Google logo whenever I sign in to my account?  Thanks for your help.
