What Is Oo01.biz?
Oo01.biz is a questionable website which attempts to trick users into subscribing to its browser notifications. Oo01.biz claims that users need to click or tap Allow on its notifications confirmation pop-up to prove that they are not robots, to confirm that they are of age, to play a video, or for another reason. If a user clicks Allow, notifications from Oo01.biz will begin showing up periodically in a corner of the screen (or on the lockscreen and status bar if it’s a mobile device). The notifications will advertise shady sites, prompt users to download something, spam them with fake messages, etc.
