I worked on a system that would get large, annoying, sometimes bizarre, ads in the lower right portion of the desktop, right above the systray. In this particular case, they were coming from https://daily.foundation
If the ads say Google Chrome - some name then you can remove them by following the steps below:
- Click the 3 dot menu item in the upper right portion of Chrome
- On the menu click 'Settings'
- Scroll to the bottom of the Settings menu and click 'Advanced' (if Advanced options are already exposed you will see them listed under 'Advanced')
- Under 'Privacy and Security' click on 'Site Settings'
- In the list of Site Settings, click on 'Notifications'
- You should see 'Ask before sending', make sure the slider is turned on
- Under allow, look for any websites you don't want to be allowed to automatically pop up things, like ads.
- To the right of an unwanted site, click the 3-dot menu item
- On the menu that pops up, choose 'Block'
- Repeat this for any and all sites you want to block
- You can close the Settings window once you have made the above changes
- Hopefully, those annoying ads will be gone now
