The Anticalser.club pop-ups are part of a tactic that utilizes social engineering techniques to convince users to subscribe to browser notifications from the corresponding corrupted website. The deceptive error message that appears on the website says:
“Anticalser.club wants to Show notifications
Click Allow to confirm that you are not a robot!”
Once the users click on the “Allow” button, they start receiving constant pop-ups from Anticalser.club on their devices directly, even when their browser is disabled. The unwanted spam advertisements may promote online games, websites with adult content, fake software updates, or potentially harmful applications and tools.
The only way to block the annoying advertisements from showing up is to delete Anticalser.club permission to display browser notifications. This scheme affects all popular browsers on Windows and Mac, and users typically land on this page after visiting other unsafe websites that contain links or advertisements that redirect to it.
A free of charge browser extension like Adblock can block corrupted advertisements. However, if you keep seeing unwanted pop-ups even after the permission was retrieved or after the installation of an ad-blocking application, your computer might be infected with an adware program or a browser hijacker. These programs may have changed your browser settings to redirect you to threatening sources on the Internet.
