This entry provides a viable method to remove DNS Unlocker, a potentially unwanted app that tweaks Ethernet settings and displays annoying ads on web pages.

The application called DNS Unlocker is a wolf in sheep’s clothing. On the face of it, this piece of software claims to help expand one’s media horizons. To this end, it promises to make geo restricted content available to people in some parts of the world by proxying their web traffic. In the upshot, it will supposedly appear that the person’s location is different than it actually is. Such a feature is definitely a godsend to many as, ideally, it should unlock such immensely popular services as Netflix, CBS, HBO, Spotify, Crackle, ESPN, BBC iPlayer, and the ITV Hub. So far so good, it seems. However, once a user installs this applet in anticipation to enjoy their favorite TV shows without restrictions, some things start getting out of hand on the computer.

While doing the proxy modification part of its purported objective, DNS Unlocker turns out to also interfere with the Ethernet configuration on an infected host. Moreover, it does so without clearly requesting user permission. The consequence of this unauthorized meddling is that the rogue tool gets privileges to change the way web pages are rendered to the victim. It literally wraps visited sites with a virtual layer, where arbitrary information can be embedded on top of the original content. Therefore, when on a web page the user will additionally see various sorts of ecommerce stuff. It includes splash screens, comparison shopping boxes, deals, banners, interstitial ads, and hyperlinked keywords all over the place.

These redundant artifacts tend to be labeled “Ad by DNS Unlocker”, “DNS Unlocker ads”, “Brought to you by DNS Unlocker” or similar. Along with the irritation nuance called forth by such routine, a particularly disconcerting thing is that these advertisements look targeted. That’s because the perpetrating program performs user activity tracking in the background. It has permanent access to the prey’s Internet history and search queries made, which is a red flag indicating privacy violation to an extent. To top it off, DNS Unlocker adds a few extra seconds to the regular page loading time, which is quite a drag as well.

The way this pseudo proxy solution infiltrates PCs is fairly prosaic. It goes bundled with various freeware applications distributed via fishy software download resources. The catch is in installation clients that ostensibly streamline the setup of a program of one’s choice but end up cross-promoting extra items. It’s in anyone’s best interest to opt out of the default (recommended) installation option in scenarios like that. Users should instead go the custom route in order to be able to see what else is under the umbrella of the compound setup. Anything that doesn’t belong on a computer, such as the DNS Unlocker virus, should be deselected at that point. In case the culprit is already inside and doing its misdemeanor, be sure to stick with the following walkthrough to get rid of noxious ads and correct the settings defiantly changed by the infection.
