DNS-Keeper-adsIn case you have seen advertisement pop-ups on the words, typed on your favorite shopping site with the down-right caption, going by the name of ‘Ad by DNS-Keeper’, you have an ad-supported PUP (Potentially Unwanted Program). DNS-Keeper is believed to be installed directly onto the operating system with the assumptions of causing PC slowdowns. It also may display targeted advertisements, based on browsing related information, concerning user interests.

DNS-Keeper – What Does It Do?

Like many other ad-supported applications, DNS-Keeper is seen to display advertisements that lead to unknown third-party sites that in most cases have nothing to do with what the user initially clicked on for. However, what is different than most adware PUPs is that DNS Keeper may make any words on a website hotlinks for adverts. What it is reported to do is when the mouse is over a word, such as Windows 10, for example, it displays a legitimate looking pop-up balloon next to it. It may contain ad similar to ‘Get repair tool for Windows 10!’ along with a ‘Click Here’ button. This may in some cases redirect to malicious websites that might:

→ Install malware on the user PC.
Input malicious code on the machine.
Display surveys that prompt for financial credentials.
Trick the user into filling out fake registration forms with personal information for prize claiming or free product trials.

Cyber-criminals have become even smarter in their strategies for obtaining user information. For instance, they often change the names and the partially the code of their applications. However, the principles remain the same. Also, they may modify the encryption of malware in case they install any on the user PC, making it undetectable by the average antivirus program. This is why, experts recommend installing a professional anti-malware tool that will scan the user PC and find anything out of the ordinary, even if the threat is new.

How Did I Install DNS-Keeper?

Apps like DNS-Keeper may come bundled with other programs such as free media players, video converters, image editors, and others. Such apps are usually either developed by the same creators who bundle them to increase their downloads or third-parties, including DNS-Keeper for profits. It may also come as a direct download if a user is tricked that it could be useful to his/her PC.
