What Is Lan03.bid?
Lan03.bid is one of many dubious websites which try to trick users into accepting notifications request from those sites. Lan03.bid claims that users have to click or tap Allow on its “Show notifications” pop-up box to confirm that they are of age, to start a download, to watch a video, etc. If someone does click Allow, notifications from Lan03.bid will start showing up in the top-right or bottom-right corner of the screen (or on the lockscreen if it’s a smartphone) time and again and spamming users with ads, clickbait links, software offers, fake messages, invitations to join adult chatrooms, etc.
