Chrome Device Support Library causing ads

Hello, long time reader - finally decided to post.

I bought the Note 5 on launch day, and have overall been very happy with it, especially after debloating. I had been noticing over the last couple weeks that a lot of websites would have ad choice ads on the bottom of the pages, through Chrome or through apps that use WebView. It was only on certain sites. When I went to my own personal sites, I would never see the ad so I was sort of thinking it was the site. But the more and more I saw them, they really seemed out of place. I dont use many apps on my device, and am very careful what I install so I was not worried about malware.

I finally decided to start disabling things to see if I could get these ads to stop, and sure enough, when I disabled Chrome Device Support Library (assuming it came installed as I did not install it), the ads went away.

Does anyone have any similar experience? I am missing anything by disabling this? I just want to make sure I don't have anything additional that would have caused these ads.

Thanks in advance for any info.
