Do you keep getting “Ads by DNS Unlocker” pop-ups on your computer screen whenever you’re browsing the web? We understand how frustrating that can be and are here to help. In today’s post, we’ll show you how to delete the DNS Unlocker virus. But first, you need to understand what DNS Unlocker is and how it affects your PC.
What Is DNS Unlocker?
DNS Unlocker is a piece of adware that gets installed on your computer without your knowledge or permission. Adware programs are potentially unwanted programs (PUPs) that get installed on your PC through deceptive means – in most cases, through software bundling. DNS Unlocker is advertised as a tool that allows users to access blocked sites. However, this adware is simply a ploy to deliver targeted ads. It displays intrusive ads regardless of the website visited.
DNS Unlocker usually gets installed on your favorite browsers, including Google Chrome, Microsoft Edge, and Mozilla Firefox, as a browser extension or an add-on. The adware then hijacks your browser in order to display irritating pop-up ads, banners, coupons, and link ads on virtually every web page you open. These ads offer to install purportedly useful software to enhance your user experience. The truth is that clicking on these deceptive ads puts your PC at risk of getting infected by dangerous malware.

Why You Should Remove the DNS Unlocker Adware
Cybercriminals are always hunting for victims who have valuable information stored on their computers. When they get their hands on that type of data, they may threaten to expose it to the whole world or use the data for illegal activities, such as identity theft. Adware programs like DNS Unlocker collect sensitive data like geolocation, IP addresses, browsing information (such as viewed pages, visited sites, search queries, browser cache, browsing history, and saved passwords, etc.), bank details, keystrokes, and so on.
As you can see, this type of information is confidential and you wouldn’t want it leaked. That’s why adware programs should be removed from your Windows machine as soon as you detect their presence.
Is DNS Unlocker Unsafe?
Adware programs like DNS Unlocker are designed to fish for valuable data that can be sold to third parties to generate revenue. For that reason, DNS Unlocker is not safe to be allowed to run on any Windows computer. It’s a threat that should be eliminated immediately. Keep reading this post to find out how to remove DNS Unlocker ads.
“How Did DNS Unlocker Ads Get into My PC?”
PUPs like DNS Unlocker are distributed through various means. In most cases, users are not careful enough when downloading and installing software and cybercriminals take advantage of this oversight to hide additional programs in the main software.
Here are some of the common ways that adware programs could infect your PC:
- Software bundling – the majority of free software offered by third-party download sites are bundled with additional programs that supposedly offer more value to your browsing experience. If you check the installation process closely, especially if you select “Custom” or “Advanced”, you’ll notice that there are other programs offered along with the main software. Most of these programs add no real value to your PC and are highly likely to be some type of malware.
- Pop-up ads – the ads that appear on your screen may offer great “discounts” on certain products or services to trick you into clicking on them. Once you do, you open a backdoor through which the adware can infiltrate your system and modify your browser settings to display other ads or forcefully redirect you to other bogus websites.
- Installing software from untrustworthy websites – some sites encourage users to download programs called “Installers”, “Download managers”, or “Download tools”, claiming that these programs enhance the download process. However, they are adware, and before you know it, your browser is filled with all sorts of pop-up ads that make the whole browsing experience very frustrating.
- Transferring files using an infected USB flash drive.
Symptoms of the DNS Unlocker Virus Infection
We mentioned earlier that PUPs like DNS Unlocker sneak into your PC without you even realizing it. However, when you notice one of the symptoms below, chances are high that you’ve been infected:
- Your Internet speeds are slow, yet the speed tests are normal.
- Webpages, apps and the Windows system load slowly.
- You notice high CPU usage caused by suspicious processes running in the background.
- Strange browser extensions appear on your browser.
- Strange shortcuts and icons appear on your desktop.
- Your browser’s homepage and start page are suddenly changed, and you’re constantly redirected to unsafe sites.
- Random adverts appear out of nowhere, and each ad displays the text “Ads by Unlocker”.
Tips to Avoid Future Adware Attacks
Admittedly, adware is designed to be sneaky and it’s not easy to know how you’ll be targeted. However, here are a few measures that you could take to protect yourself from future attacks:
- Never click on pop-up ads no matter how legitimate they look. The links on these ads will redirect you to malicious websites that could infect your PC with malware.
- As much as getting free software is enticing, you need to be extra careful not to download and install malicious apps. Avoid downloading files via peer-to-peer sharing networks, online game sites, and third-party downloaders.
- Configure your browser to block notifications from untrusted websites.
- Download or update software from verified sources only.
- Perform regular malware scans on your PC.
- Be sure to keep your software, browsers, and the Windows system up to date.
