Why do I keep getting spam ads and intrusive web pages every time I unlock my Note 8?

[Android Central Question]

Every time I unlock my Note 8 or log into an app, my internet browser opens with spam ads or intrusive and vulgar web pages. How do I stop this? I have cleared the data, cleared the cache, disabled the google chrome, too permissions away from cookies, java script and internet notifications. I have also restarted the phone without success... I keep getting the google ads that also my note has a virus and I have 4min 56 sec to remove it. This is quite annoying.

Welcome to Android Central! Does the Note8 only have Chrome, or does it also have the Samsung Internet browser? If the latter, then can you tell if the popups are coming up on Chrome or Samsung Internet?
