DNS Unblocker, also frequently referred to as DNS Unlocker, is a piece of software that cannot possibly be characterized unambiguously. The first glimpse at its features may call forth the impression that it’s a fast-operating tool for accessing certain sites which restrict web traffic for some users. The program’s official site includes further reassurances that it enables people to circumvent geolocation-based blacklisting of ISPs based out of a number of countries – so far so good. The problem, though, is that along with the ability to watch and listen to popular content on services like ITV, CBS, Crackle and the like, users also acquire an awfully pesky ad-generating entity that plays quite a havoc with the web surfing side of their computer usage.
In order to accurately understand the scope of the trouble, the specificity of functional aspects of DNS Unblocker should be taken into account. The way it makes restricted websites reachable is it interferes with the network settings on the machine. In particular, the app assigns new values for the preferred and alternate DNS server under Internet Protocol Version 4 properties. This modus operandi isn’t typical for other adware programs, therefore DNS Unblocker ends up getting broader privileges on the box than the more commonplace infections of this kind. Strictly speaking, the software can easily inject arbitrary content into websites without hindrance, which it actually does. That’s why it’s important to complement the virus removal part of fix with activating the option to obtain DNS server address automatically, which is a Windows feature available under Local Area Connection parameters.
The main and worst collateral influence of DNS Unblocker is intrusive advertising. No matter how safe the victim’s preferred browser is believed to be, web pages opened in it will contain excessive items on top of the initial layout components. Some words on sites will be displayed in all caps, with “Ads by DNS Unblocker” pop-ups springing up from them. Be advised this isn’t the webmaster’s plan if you see this – it’s the virus adding stuff that shouldn’t be there. Other issues include the random appearances of coupon notifications as well as fabricated software update alerts, comparison shopping charts, eye-catching banners and transitional ads.
All of these malign artifacts get too ubiquitous across every opened browser tab, so the user experience element will rapidly go down the tubes. This article’s removal chapters are composed of concise steps that lead to thorough withdrawal of every constituent of the DNS Unblocker virus.
