What is DNS Unlocker?

The DNS Unlocker application supposedly allows users to access blocked websites, however, it is categorized as adware and a potentially unwanted program (PUP). The developers employ a deceptive software marketing method called 'bundling' to distribute DNS Unlocker, and therefore, this type of app is often bundled with free software downloadable on freeware download websites. Many users do not pay close enough attention when downloading and installing programs - cyber criminals use this oversight to their benefit and to generate revenue. DNS Unlocker infiltrates popular Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) and generates intrusive online advertisements. Adware-type applications (including DNS Unlocker) deliver adverts using a virtual layer, which displays third party content on any websites visited. Furthermore, some advertisements are opened in new Internet browser tabs/windows. Ads displayed by DNS Unlocker (banner, pop-up, targeted video, coupon, offers to install other software, etc.) can cause high-risk computer infections, and therefore, you should never click unrecognised/suspicious advertisements.

As with regular adware, DNS Unlocker collects various information relating to users' Internet browsing activity. Although the Privacy Policies of most adware-type applications claim to track non-personal information, your identity will not remain anonymous with this software installed. Collected information may include Internet Protocol (IP) addresses, geographic location, browsing information (visited sites, viewed pages, search queries, browsing history, cache, web beacons, saved passwords, etc.), mouse/keyboard inputs (to record, for instance, credit card details), and so on. This gathered information is sent to the developers' servers and then shared with third parties. There is a high probability that this collected data will be shared with cyber criminals, thereby causing serious privacy issues or even identity theft. For these reasons, adware-type applications such DNS Unlocker should be uninstalled from your system immediately.

DNS Unlocker is identical to CloudScout adware. Moreover, there are hundreds of other PUPs that share similarities with this deceptive application including PriceFountain, BaselineTV Media Manager, thirteen degrees, and Application Nation. These PUPs offer useful features, however, they are developed simply to generate revenue by displaying ads and sharing collected data - they provide no real value to the user. Freeware download websites (such as downloads.com, softonic.com, soft32.com, etc.) encourage users to use small download programs (called 'installers', 'download managers', 'download tools', 'download clients', and so on) to download the chosen software. Download apps supposedly ease the download process, however, they offer installation of third party applications with the chosen software. Furthermore, these promoted applications are described as 'legitimate and virus-free', and yet, most are categorized as adware or malware. Therefore, decline all offers to install additional apps. If you have installed DNS Unlocker, read the following guide and eliminate this threat from your system.

How did DNS Unlocker install on my computer?

DNS Unlocker is distributed using the bundling method - stealth installation of third party applications with regular software. Research shows that users often skip steps of software download and installation process, making this method highly effective. Installation of additional applications is usually hidden under the 'Custom' or 'Advanced' options, thus, skipping this step prevents users from seeing bundled software listed for installation from which they could otherwise decline.

How to avoid installation of potentially unwanted applications?

Pay close attention and closely observe the download process of free software. Opt-out of download/installation of any unrecognised applications. In addition, after downloading software, install it using the 'Custom' or 'Advanced' options - this will reveal any concealed applications listed for installation and allow you to decline them. Do not rush the installation process and express caution, otherwise you may inadvertently install potentially unwanted programs.

Vanessa Tate

This has affected my computer and I can't even get past my login...it then says 'Loading Script ....access is denied. after that it's blank. Please help! Has all my family photos & videos..thats all i want back,

Simple Simon Says

It got on my machine just reading a paper, the daily express, when i loaded the paper the screen went black, would not come back so i turned it off then on again and when it restart it had this dns unblocker on it, i have tried to remove it but failed, also many of the sites that say they will remove it are fakes, many people offering a solution give you links that dont remove it but make sure it stays, this should be seen as terrorism, the machine it is on is ruined, cant use any web browser, the newspapers are going bust and desperate for money by any means, i have made a list of the company's advertised and me and my family will boycott any company advertised for life, maybe if they have no companies to advertise they will police it, but these people are terrorist and there should be life sentences given when caught. dont use the malewaretips site, it will not remove it just make sure you cant

Troy Knox

Yep. My Android devices keep getting this problem too. I clear the browsing history inside chrome, then delete the app data and cache and reboot my phone and it disappears for a while, but I believe I've been getting it back from browsing smh.com.au (Sydney morning herald).. It's driving me nuts!

URGENT: DNS Unlocker is now asserting itself on all devices via compromised websites such as Tunein & deviantArt and most likely other sites just by being on the compromised site & it's affecting all OS's now like Android & Windows Phone 8.1 & 10 and most likely Linux as well.

Would suggest that this is now a threat on a global scale and could be a prelude to a Cyber Attack on a scale not seen before & urgent action needs to be taken...

I don't have DNS Unlocker installed on this PC & yet my Chrome has been compromised & I did a reset of my Chrome and it returned as soon as I was on deviantArt.com. :/

Also both my Android based tablet & Windows 8.1 phone based cellphone have been now compromised as well & that's because I'm using Google Chrome on the Tablet and Internet Explorer on the cellphone and they both succumbed to it.

At the time I wrote this Firefox Does Not seem be affected by this new insidious threat & would highly suggest that you use the latest version of Firefox to avoid getting your devices compromised and updating your antivirus and anti malware software as well.
