The controversial story of DNS Unlocker software got a kick-off into the public realm with a thread created on VIDCreek.tv online sharing community. In early June 2015, the site admin announced a project purportedly intended for bypassing filters which restrict user access to a variety of Internet resources based on the visitors’ DNS servers. Considering the free-of-charge operational mode, this startup initially seemed like a great opportunity for people living in some countries to surf the web without limits and fully enjoy services like NetFlix, Spotify, ESPN, CBS, HBO, Crackle, ITV and BBC iPlayer, all of which would otherwise be blocked. In the long run, however, customers and IT experts came to realize that this was in fact a well-orchestrated campaign aiming at unauthorized ads serving on a large scale. The predicament that DNS Unlocker clients end up in is, obviously, a lot weightier than the advantage of using custom servers provided by the product.
The way DNS Unlocker emulates online connection attributes, as promised, is a double-edged sword. On the one hand, the program does indeed make it look like the requests are originating from an allowed valid server so that certain sites can be accessed despite the blocking. On the other, the fact that it modifies one’s Internet Protocol properties enables it to be in full control of the content presented to the client. This is the instrument leveraged for injecting sponsored information into arbitrary places on visited web pages.
As a result of this interference, the victim will keep stumbling upon automatically generated text ads, bogus software update reminders, comparison shopping elements, banners, as well as interstitial and transitional ads. The volume of this unsanctioned advertising tends to get so big that websites will appear difficult to view and scroll through, with irritating popups and other redundant items that say “Ad by DNSUnlocker” emerging at random. Going back to the normal web browsing routine under these circumstances isn’t easy. It’s not only the harmful software that needs to be uninstalled. In fact, remedying the system is also a matter of reconfiguring the Local Area Connection as well as conducting some additional in-depth cleanup. Most questions that may occur in the course of this troubleshooting are answered below. It’s a do-it-yourself guide to completely solve the DNS Unlocker adware problem.
