What Is Se20.biz?
Se20.biz is one of many questionable sites which attempt to trick users into subscribing to push notifications from those sites. Se20.biz claims that users need to click Allow on its “Show notifications” pop-up box if they wish to view a video, open a page, verify that they are not bots, confirm that they are 18+, etc. If a user clicks Allow, Se20.biz notifications will begin spamming him or her with ads, links to untrustworthy websites, prompts to download something, invitations to join adult chatrooms, etc. The notifications will appear in the bottom-right corner of the screen on Windows or in the top-right corner on macOS.
