How to Remove DNS Unlocker Adware (2021 Fix)

If you’re experiencing unwanted pop-up ads or intrusive push notifications labeled Ads by DNS Unlocker while browsing the web, it usually means an adware program was installed on your computer. This program was created by cybercriminals who use deceptive methods to infect people’s computers without consent. This type of adware can gain access to your personal information and online activity, making it a threat to your data security. Aside from being a major nuisance, the ads displayed by DNS Unlocker can cause unwanted computer infections if you click on them.

Luckily, there are a handful of ways you can troubleshoot this issue and remove DNS Unlocker from your computer. Read on to learn more about how DNS Unlocker works and how you can remove it yourself at home.

What is DNS Unlocker?

DNS Unlocker is an adware program that takes over your internet browser with unwanted ads. Its main purpose is for cybercriminals to gain profit through advertising revenue as a result of victims clicking on the ads. The ads usually promote questionable third-party software and products such as web browser toolbars and optimization utilities. The ads will always contain some variant of the DNS Unlocker label, including:

• Powered by DNS Unlocker
• Brought to you by DNS Unlocker
• RocketTab powered by DNS Unlocker
• Ads by DNS Unlocker
• Ads powered by DNS Unlocker

In addition to displaying unwanted ads, DNS Unlocker also collects personal data such as your IP address, location and specific mouse and keyboard inputs. It also collects data about your internet browsing activity, such as the sites you visit, what pages you view, your search queries, your computer’s cache, saved passwords and more.

Because of all the personal data gathered by DNS Unlocker adware, it poses a serious threat to your online privacy and should be removed as soon as possible.

How Was DNS Unlocker Installed on My Computer?

The developers of DNS Unlocker adware use deceptive methods to plant the program on unsuspecting users’ computers. They often use a method called “bundling” where the program is combined with other free programs that you intentionally download. Usually, these free programs don’t disclose the fact that other software programs will be installed on your computer. Unfortunately, most of us don’t read the fine print when downloading software from around the web, and cybercriminals use this to their advantage.

How to Uninstall DNS Unlocker: 5 Methods

While the steps for removing DNS Unlocker adware from your computer might look overwhelming, they’re actually fairly simple to follow.

If it does, uncheck the box to the left of the item entry. (Unless you see a program listed that you know shouldn’t be removed, continue to the next step.)
5. Select Clean from the AdwCleaner screen.
6. You will be prompted to save any open files or documents (any open programs must be closed for AdwCleaner to complete the cleaning process.) Do so now.
