Pkrqiu.info is a deceptive website that specializes in running scams and spreading potentially unwanted programs (PUPs). It tricks users into subscribing to its browser notifications so it can send unwanted advertisements directly to a user’s desktop or phone. The site may infect computers by using social engineering tactics, such as displaying fake error messages or promising rewards, to trick users into granting permission for these notifications. It might also bundle itself with other software, infiltrating a computer when the user installs this software unaware of the hidden extras. The Pkrqiu.info site is designed to exploit browsers like Google Chrome, Mozilla Firefox, Internet Explorer, Safari, and others. It doesn’t discriminate between devices, meaning it can infect both Windows, Mac computers, and even mobile devices. It exploits browser notifications by sending intrusive advertisements and possibly leading users to other malicious sites. Once the user has inadvertently agreed to receive notifications, the site can flood them with pop-ups, even when the browser is closed. These pop-ups can redirect users to harmful domains that can lead to system infections.
