What is DNS Keeper?

According to the developers, the DNS Keeper application provides free DNS services allowing users to unlock blocked websites and digital media. On initial inspection, this functionality may appear legitimate and useful, however, DNS Keeper is classed as adware and a potentially unwanted program (PUP). Be aware that DNS Keeper often infiltrates systems without users' permission. Although it claims to be legitimate software, DNS Keeper displays intrusive online advertisements and monitors Internet browsing activity.

DNS Keeper adware

To display advertisements, the developers employ a virtual layer, which enables placement of third party graphical content on any visited website. Note that the displayed advertisements (banners, pop-ups, coupon, targeted video, etc.) do not originate from the visited webpage. These ads often conceal underlying webpage content. After clicking the ads, users might be redirected to bogus sites containing infectious content - thus, causing further computer infections. Another downside of this software is information tracking. DNS Keeper collects a wide range of information such as Internet Protocol (IP) addresses, geolocations, web browsing information (websites visited, pages viewed, search queries, cookies, web beacons, cache, etc.), keyboard/mouse inputs, and other similar data. This information might contain personally identifiable details that DNS Keeper later shares with third parties. Therefore, having this app installed on your system can lead to serious privacy issues or even identity theft. You are strongly advised to uninstall DNS Keeper immediately.

There are hundreds of applications sharing many similarities with DNS Keeper including Unfollow Alert, Unfriend Review, and Computer Pal. In fact, DNS Unlocker and CloudScout are identical to DNS Keeper. All adware-type applications claim to be legitimate and enhance the Internet browsing experience. These are simply attempts to give the impression of trustworthy software - the apps deliver little or no real value for the user. Their purpose is to generate revenue by displaying advertisements and collecting personally identifiable information.

How did DNS Keeper install on my computer?

As with previous examples, DNS Keeper is distributed as a 'bundle' with regular (mostly free) software. Research shows that many users lack caution when downloading and installing software. Developers take advantage of this by intentionally concealing installation of bogus applications within the 'Custom' or 'Advanced' settings. Users commonly skip most/all of the download and installation procedure steps, thereby exposing their systems to risk of infection. The developers are concerned only with the amount of revenue generated, and thus, do not properly disclose installation of PUPs.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Do not rush the download and installation processes. Closely observe each step when downloading your chosen software to ensure that no third party applications are included. Furthermore, installation of downloaded programs should be performed using the 'Advanced' or 'Custom' options, rather than 'Quick' or 'Typical' - this will reveal any bundled applications listed for installation and allow you to opt-out.
