What is DNS Unlocker? And how does it function?

DNS Unlocker is an application that claims to allow users into accessing blocked websites online. This application may seem like a useful one however, it is actually categorized as an adware and a potentially unwanted program. One of the reasons why it is considered to be a PUP is that this program employs a deceptive software marketing method known as software bundling.
This program might appeal to you as it looks like a legitimate program when actually it’s not. DNS Unlocker’s website promotes this program that could “unblock blocked websites and digital media – because of this description, many users were tricked into downloading and installing the program with the belief that it will help them access restricted media and sites. What users don’t know is that this program is nothing but an ad-supported program and an unwanted one which is created mainly for the purpose of increasing its revenue by displaying dozens of intrusive ads – many of which are intrusive.
According to researchers, this unwanted program is capable of hijacking browser’s settings and alters them with new ones without users’ permission. It could also redirect users to tech support scams or browser-based scams as an ad-supported program are known to cause these kinds of redirects where it aims to trick users into thinking that their computers are infected with some harmful virus and that they either have to call a fake certified technician or install some suspicious program. So if you happen to be one of the users who has installed or unknowingly installed this program, keeping it installed on your computer would only put your computer at risk.
