Uninstall Ads by DNSUnlocker and ‘DNS Unlocker version 1.4’ from Windows

Implement this fix for the collateral effects of DNSUnlocker software, in particular the advertisements that it serves on websites without being permitted to.

A variety of proxy services available on the e-market allow exploring and enjoying the multimedia services that use blacklisting techniques for certain categories of users. Sites like Crackle, Netflix and HBO, for instance, employ traffic filtering so that people cannot visit them from quite a few places across the globe. This take on treating customers is presumably a countermeasure for the violation of copyright and spreading illegally obtained media content without consent of the proprietor. Virtual private networking tools can dodge this blocking by imitating the client’s server location that won’t raise any red flags. While this approach might have a flavor of cheating in certain circumstances, it is undoubtedly also a useful instrument to maintain anonymity on the Internet. DNSUnlocker is a brand that takes advantage of this positive perception, but the things it does to one’s computer reduce the good part down to zero.

DNSUnlocker has an official web page, where the claimed benefits are presented in a good light only. According to the vendor, this tool is better and faster than the regular VPNs because its effect only covers the geolocation-related attributes of one’s web traffic. So, the users supposedly get a lightweight app that enables them to visit geo-restricted domains without having to sacrifice their connection speed and pay anything. After this product is installed, though, it’s going to make web browsers freak out by injecting huge amounts of sponsored data into sites. User experience, therefore, will definitely be affected as well.

One of the things DNSUnlocker does to the computer system is it makes changes to the local area connection parameters, which is part of the server imitation routine that’s necessary to make restricted web pages accessible. However, these changes and other software-level interferences let the program perform unwanted actions on the browsers. All websites will be henceforth filled with in-text ads, price comparison objects, coupons and popups with the inscription “Ads by DNSUnlocker”. Interstitial advertisements will be encountered as well.

Another must-mention fact about this malicious program is that users never install it in a regular way. Tens of freeware offers downloadable from software repositories have DNS Unlocker included in their installation by default so that it gets into PCs alongside these tools. Overall, when looked at from different angles, this application is a fraud that should be avoided. If it has already attacked a computer through the covert spreading hoax, removal should be immediately carried out in accordance with special instructions.
