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.
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.
