Today, 1/30/2018, when I went to check my email I got a page for Polaris. What is it? Am I supposed to install it?
Is this something that only pertains to Comcast servers and not me? Then why is it showing up when I log in to check my email.
Never install anything you weren't expecting. It has nothing to do with Comcast I'm aware of. Try clearing out your browser's cache/browsing history. When you have done that, close out the browser and re-start it in a fresh session. Then sign out of your email and back in again. Does the same page come up?
