While these may look like ads they're actually site notifications, which means the only way to get rid of them is to change your Chrome settings. Here's how to change your settings in Chrome so that you no longer see those annoying Windows pop-ups:
Disable Site Notifications in Chrome
- Click the Chrome menu (the three vertical dots in the upper right corner of the Chrome window) and select Settings
- Under "Privacy and security" click Site Settings
- Under "Permissions" click Notifications
- Turn off notifications from any site you no longer want to see notifications from
If that doesn't stop the pop-ups, the ads might be adware.
