The aggressive marketing campaign by cyber criminals includes the harmful website Qr-captcha.com. The majority of the advertisements emanating from this domain run the risk of directing users to undesirable websites like adult, gambling, phishing, and scam sites, as well as false online surveys with phony awards. Furthermore, Qr-captcha.com pop-up ads promote questionable products by disseminating bogus software updates, phony optimization tools, and phony anti-virus programs. It is obvious that accessing advertisements through Qr-captcha.com is bad for the browser and computer system as a whole.
Why does Qr-captcha.com appear in my browser?
A sequence of redirects from previously visited websites, especially those involved in the unlawful distribution of copyrighted media, including software, movies, and audio files, commonly lead web visitors to Qr-captcha.com. On their first visit to the suspicious website, online users will notice a message that says “Qr-captcha.com wants to show notifications.” Because of users’ casual answers to this pop-up message, the website was frequently able to make use of the push notification feature of the default browser program. As a result, the browser window on the Qr-captcha.com website can show bothersome pop-up ads.
