Random popups after visiting a sketchy website

I recently visited a sketchy website, one where everytime you click, it opens a new tab. This time, it opened a new tab then immediately disappeared. Now I am getting random notifications from chrome. I ran a quick scan using mcAfee, but it didn't detect anything. I looked at task manager, and more specifically I opened up task manager through chrome to see what was going on. I saw a couple of things appearing and then disappearing. All I want is a way to stop these notifications, without having to turn off notifications for chrome. In the picture, you can also see a weird address on the notification. There was also something else I saw that was called, "Extension: Chrome media router" that is not seen in the pictures.
Using Windows 10 and chrome.

Here is another popup that came up recently

I downloaded MalwareBytes. I ran it twice so far, and each time it has found about 12 files. The problem is still happening, but hopefully after a couple of more scans it will find the source. I also tried uninstalling and reinstalling chrome, but I didn't use Geek uninstaller.

Thanks Callender. I found the website that was spamming notifications and blocked it.
