How do I keep pop ups from coming onto my screen?
Try looking under settings on your computer or security settings and see if there is a pop-up blocker you can select to turn on.
Go to your settings.
Turn on Your Pop-up blocker
get rid of the computer
If you look under Tools on your top taskbar, you will see where to turn on your pop-up blocker. With Chrome, you do it in your settings.
