Why Can’t I Remove DNS Unlocker?

DNS Unlocker has been around for a few years now, and still continues to be one of the most persistent adware pieces in the wild. In 2017, catching an intrusive and persistent potentially unwanted program like DNS Unlocker continues to be one of the nastiest unwanted PC intrusions. Perhaps you have encountered that nasty piece of code yourself, believing it will truly unlock geographically restricted websites, as suggested by its name.

Having an intrusive adware such as DNS Unlocker running in the background of your system, however, may have worse outcomes than the display of unwanted ads. On top of everything else, the adware is quite challenging to uninstall from a system and has caused many headaches around the globe. This article provides detailed information about the adware and its methods of distribution. We have also provided an overview of the threat focusing on how it became so successful. It’s important to pay attention to these details. Knowing how the program sneaked into your system in the first place will help you prevent future intrusions. Education is the best prevention, especially when it comes to online threats. In addition, the fact that multiple antivirus programs detect the threat hasn’t stopped it from accessing users’ systems.

When Did the DNS Unlocker Nightmare Begin?

The very first time the program landed the Internet is in the autumn of 2014, when users were first tricked by the luring promise of DNS Unlocker. Our research indicates that back then the program was referred to as Netflix DNS Unlocker, maybe because it was somehow associated with Netflix or because it was advertised like this on dnsunlocker(.)com. Indeed, the Netflix logo is still situated on the homepage of the adware, along with other services DNS Unlocker promises to unlock.

Whatever the case was, the scenario worked because soon after its first release, there were many victims complaining over the Internet, sharing negative experience and trying to figure out a way to completely remove DNS Unlocker.

Not surprisingly, a counter-action followed on the side of the developers of the adware. In 2015 the direct download button on the dnsunlocker(.)com site was removed, and later in the year, its Privacy Policy was changed. However, disabling the direct download didn’t mean that the program ceased to exist. That’s a general practice often used by developers of unwanted software. The app just moved to bundling, meaning that it was distributed packed with other dubious software pieces.

According to a research, titled Investigating Commercial Pay-Per-Install and the Distribution of Unwanted Software, unwanted software and particularly the pay-per-install method is part of highly profitable global industry, protected by layers of deniability. No wonder the bundle business is so successful!

DNS Unlocker Distributed via the Pay-Per-Install Scheme?

Indeed, there’s a strong connection between pay-per-install practices and the spread of unwanted applications.

Symantec researchers have previously dubbed pay-per-install “the new malware distribution network”, stressing on the fact that in the foreseeable past malware (like worms) was self-propagating with the help of server-side vulnerabilities. The research results also depict the deceptive practices of some commercial PPI operators that currently persevere, and will likely continue to do so in the future.

Commercial PPI is a very effective monetization scheme where third-party programs are bundled with legitimate software. Even though it hasn’t been confirmed that the developers of DNS Unlocker have adopted this distribution method, we wouldn’t be surprised if DNS Unlocker was indeed distributed this way. It’s the easiest way to monetize software, be it bad or good.

What’s indeed quite surprising about DNS Unlocker is that it’s still successfully affecting users all over the world! Even though multiple antivirus programs detect the threat, users are still being entangled in its tentacles.

Here’s the VirusTotal list of antivirus programs detecting DNS Unlocker. The list is based on a scan of the file dnslockington.exe:

DNS Unlocker is a great illustration of how well dubious developers are acquainted with human psychology. Part of the success of the adware is the very fact that it was advertised as a mean to access to inaccessible content, freely. However, nothing in life comes for free, as victims tricked by the promise ended up with systems compromised by multiple adware.

How to Rid Your System of DNS Unlocker?

Because DNS Unlocker is very aggressive, simply deleting some of its files may not work to remove it permanently. If you want to try, you can remove it from your computer manually by following the step-by-step removal guide provided below. In case the manual removal method does not get rid of DNS Unlocker and all of its associated files, then you may want to try removing it with an advanced anti-malware tool. A tool like that can also keep your computer more secure in the future.

Besides following the steps below to remove the adware, you should also consider checking your DNS servers. More particularly, inspect the settings of your DNS server address and configure them if they are modified without your knowledge. In case they are tampered, you can use the IP addresses like the Google Public DNS.

DNS Unlocker-FAQ

What Is DNS Unlocker?

The DNS Unlocker threat is adware or browser redirect virus.

It may slow your computer down significantly and display advertisements. The main idea is for your information to likely get stolen or more ads to appear on your device.

The creators of such unwanted apps work with pay-per-click schemes to get your computer to visit risky or different types of websites that may generate them funds. This is why they do not even care what types of websites show up on the ads. This makes their unwanted software indirectly risky for your OS.

What Are the Symptoms of DNS Unlocker?

There are several symptoms to look for when this particular threat and also unwanted apps in general are active:

Symptom #1: Your computer may become slow and have poor performance in general.

Symptom #2: You have toolbars, add-ons or extensions on your web browsers that you don't remember adding.

Symptom #3: You see all types of ads, like ad-supported search results, pop-ups and redirects to randomly appear.

Symptom #4: You see installed apps on your Mac running automatically and you do not remember installing them.

Symptom #5: You see suspicious processes running in your Task Manager.

If you see one or more of those symptoms, then security experts recommend that you check your computer for viruses.

What Types of Unwanted Programs Are There?

Step 4: Call your bank to change your credit card details (secret code, etc.) if you have saved your credit card for online shopping or have done online activities with your card.

Step 5: Make sure to call your ISP (Internet provider or carrier) and ask them to change your IP address.

Step 6: Change your Wi-Fi password.

Step 7: (Optional): Make sure to scan all of the devices connected to your network for viruses and repeat these steps for them if they are affected.

Step 8: Install anti-malware software with real-time protection on every device you have.

Step 9: Try not to download software from sites you know nothing about and stay away from low-reputation websites in general.

If you follow these recommendations, your network and all devices will become significantly more secure against any threats or information invasive software and be virus free and protected in the future too.

How Does DNS Unlocker Work?

Once installed, DNS Unlocker can collect data using trackers. This data is about your web browsing habits, such as the websites you visit and the search terms you use. It is then used to target you with ads or to sell your information to third parties.

DNS Unlocker can also download other malicious software onto your computer, such as viruses and spyware, which can be used to steal your personal information and show risky ads, that may redirect to virus sites or scams.

Is DNS Unlocker Malware?

The truth is that PUPs (adware, browser hijackers) are not viruses, but may be just as dangerous since they may show you and redirect you to malware websites and scam pages.

Many security experts classify potentially unwanted programs as malware. This is because of the unwanted effects that PUPs can cause, such as displaying intrusive ads and collecting user data without the user’s knowledge or consent.
