Theqenadusa.com is known as a deceptive website often associated with an adware program or a potentially unwanted program (PUP). It infects computers when users accidentally download or install freeware bundled with this unwanted software. This website may also trick users into visiting it through misleading advertising or a redirect from a compromised website. Once a user visits Theqenadusa.com, the site attempts to trick them into enabling browser notifications. Theqenadusa.com exploits browser notifications by asking users to allow notifications to view the website content, download a file, or resolve a non-existent issue. Once the user clicks on “allow,” the website starts to send unwanted advertisements and possibly malicious links directly to the user’s desktop.
