360 is not recommended, use another browser. The problem of automatically popping up web pages should be that your computer has installed the player used by this video website, and all the services that depend on it have been started. It is also possible that your browser has installed a malicious plug-in for this website. Clean up your plug-ins with auxiliary software such as Kingsoft Internet Security or 360 Guardian. Open the startup item and see if there are any unnecessary ones. You'd better take a screenshot of the interface of your pop-up webpage.
