DNS Unlocker Description and Removal Steps


A questionable application called DNS Unlocker is reported to be installed bundled with other programs, such as free converters, image processing software, video players, etc. It is classified by others as adware and PUP since it may have been displaying various intrusive pop-up advertisements on key places during browsing. It is advisable not to mix it with a VPN service, because while the VPN service is suitable for browsing in different countries, this software could be potentially malicious. Furthermore, similar to another PUP, DNS Unblocker, DNS Unlocker may affect the system’s overall performance.

What Is DNS Unlocker Distribution Path?

The most often case of installing DNS Unlocker on a system is not paying enough attention when working with software setups. It could be located on one of the steps, masked as a free extra and if a user clicks on “accept” or forgets to remove the tick from it, the installation of the software proceeds.

What Does DNS Unlocker Do?

Once already located on a system, it is reported that DNS Unlocker may target all of the supported browsers (Firefox, Chrome, Safari, Internet Explorer). Once it ‘hijacks’ your browser, it will begin to display a lot of advertisements with the text “Ads By DNS Unlocker”, reports say. It is highly recommended to take extreme caution with those “Ads”, since there is chance that some of the content might be fraudulent and to some extent, may even pose dangers to the PC.

DNS Unlocker

More importantly, DNS Unlocker claims to utilize the user’s domain name service adding foreign DNS addresses. The effect of this is similar to proxies and VPN services. However, do not be fooled by the flashy ads on their website. Using DNS unlocker, you may not be able to access foreign services, quite the opposite. Except the displaying of various types of advertised content, DNS Unlocker may collect anonymous information from the user, as mentioned in their privacy policy:

As seen, DNS Unlocker may closely cooperate with third-parties. Adware apps, like this one, usually do this to profit from the pay-per-click money making schemes via generating traffic or affiliate marketing. This is the main reason DNS Unlocker may be dangerous to users. Not only does the app cause PC slowdowns and collects anonymous info, but it also displays third party advertisements. And we all know that third-party sites may be of any origin, including the malvertising kind. The malicious third-party site types may vary:

  • Conning the user out of his personal info by fake prize claiming forms and other registration forms.
  • Trick the user into giving out his financial information and lose funds by buying a product using a fraudulent online shopping website.
  • Convince the user to call non-existent customer support numbers belonging to ghost companies charging him a lot of funds for a simple call.
  • Subscribe him to expensive SMS services that generate income by automatically sending messages from his phone.
  • Infect the computer with all types of malware, including worms that scramble data, Trojans, viruses, keyloggers and ransomware Trojans that encrypt user data to extort him for money.

The DNS Unlocker Process DNSPalenville.exe

This process is associated closely with DNS Unlocker, and experts recommend its immediate ending from the System. The suspicious process is detected as WS.Reputation1 when analyzed by VirusTotal.com and it is believed to be around 536 kilobytes in size. There is a possibility that this type of detection may be associated with other executable files in other adware applications. DNSPallenville.exe may collect different browsing information directly from Chrome, Firefox, Mozilla, Safari, Edge and other widely used web browsers. It also may slow down your computer and is also believed by security experts to administer advertised content in an interruptive manner and sometimes cause applications to turn into a ‘Not Responding’ state.

Some security researchers believe that the process may modify various computer settings such as change the some elements of the desktop appearance or make any associated apps such as DNS Unlocker to be difficult to uninstall. (For example, this error message: ‘You cannot uninstall this program while it is running’)

    Hi, Lorenzo,

    It seems that the problem has been caused by either DNS Unlocker or another PUP (Potentially Unwanter Program) on your computer. In order to fix it for Google Chrome, please do the following:
    1)Open Chome
    2)On the top right corner, below the X button, click on the drop-down Customize and Control menu.
    3)From there, drag your mouse over ‘More Tools’ sub menu.
    4)From it, choose Extensions
    5)Locate any suspicious extension on your computer then remove it.
    6)Now type in the address bar chrome://settings and scroll down to the bottom of the page to find a button that says ‘Reset Settings’. It should restore chrome to its initial state.

    IMPORTANT: Make sure before resetting Chrome to save your bookmarks and passwords.
    1)To save you passwords type chrome://settings.
    2)Click on ‘Manage Passwords’. Its a blue highlighted text/button under the ‘Passwords and forms’ section.
    3)You should see a list with all the passwords. Simply click on the ones you would like to copy and click on show. Copy them either on your machine or on a piece of paper.

    If you have any further questions, do not hesitate.
    Best regards,
