Whenever I go to some webpages that include some normal ads, they show more annoying ads on left, right, and bottom sides (see screenshot). How can I remove them?
I've already checked Applications, but I found no suspicious apps.
That's most likely not adware. It's just advertising the web site is serving you. Yes, some sites are very annoying. You can try an ad-blocking extension. One I've used is "Ghostery" but there are others. Note that some websites will not let you use them if they detect such an extension. Or, they site may not work correctly.
I'm not seeing the screenshot.
If you really have installed adware, EtreCheck may be able to identify and help you remove it.
How can I remove unwanted adware? (What would be best practices to take adware off?)
