Solved How do I prevent a recurring screen redirect?

[Lenms]

I've started getting a notification from (supposedly) Gmail in the lower right corner of my screen followed in about 2 seconds by a full-screen redirect to a Google screen (https://www google dot com/gmail/about/) asking me to sign in. This activity started about 5 days ago and occurs about every 5 minutes. Of course, I close the tab, but it is very annoying and interrupts what I was doing on legitimate sites.

Has anyone else had this experience?

Any assistance would be greatly appreciated!

Thanks,
Lenms

I just noticed that this thread has a green "Solved" check mark at the top. This is not my case. I do not know to which thread the "Solved" indicator applies, but it is not mine. My PC is a personal PC used only by me.

Assuming it is Google it's happening because you haven't logged into Google if you login and remember the login it should disappear you have something of Google running which is trying to access Gmail
