What Is Se28.biz?
Se28.biz is a dubious site that attempts to trick users into accepting its notifications (see an example on the screenshot above). Notifications are messages from sites that appear in the lower-right corner of the screen on Windows and in the top-right corner on macOS. If a user allows Se28.biz to send him or her notifications, the notifications will begin popping up periodically with ads, links to shady sites, software offers, scammy messages, etc.
