Lnkr is a potentially unwanted application that hijacks popular web browsers to promote specific websites and to display aggressive advertisements in them. Normally, Lnkr connects to Chrome, Firefox, Edge and other common browsing apps and adjusts their homepage and search engine settings.


The Lnkr Malware will make unwanted changes to the browser it is installed on.

One of the most controversial features of browser hijackers is their ability to automatically redirect traffic from the hijacked browsers to specific domains that pay for user visits and clicks. This often leads to uncontrolled exposure to sponsored links and pages that users may not want to visit but cannot avoid either. Such apps also tend to cover the content of the websites visited by users with different pay-per-click messages, pop-up alerts, banner notifications and other click-bait ads and deals that aggressively promote their items on the screen.

Is Lnkr a Malware?

The way that Lnkr operates is typical for a class of software known as browser hijackers. Browser hijackers like Lnkr are tools used to promote different types of products, services, software and their related websites through aggressive online marketing methods.

People who have this software in their system can typically experience an automated change to their browser’s search engine and/or the default homepage URL. They may also start seeing way more pop-up advertisements, banner alerts and redirect links than usual and may constantly be prompted to click on them.

Nonetheless, the most annoying thing about browser hijackers is that they cannot be uninstalled with a single click and their browser “improvements” cannot be easily removed. This is the reason why the majority of people who end up with a program like Lnkr in their system tend to panic when they realize they can’t get rid of the annoying software and confuse it with a virus, Ransomware or a Trojan horse infection. What’s more, they are typically forced to deal with the new browser’s behavior and modifications without being given the chance to customize or restrict them either. Luckily, at the end of this post, users will find a removal guide that explains exactly how to deal with Lnkr and its unwanted changes. That’s why those who want to get rid of this program are more than welcome to follow the instructions that have been listed there.

Unfortunately, not everything that programs like Lnkr can promote should be trusted because no one really checks the origin and the reliability of every single advertisement, URL or pop-up that this software generates. Some of them may potentially come from unreliable web locations and may redirect users to questionable websites that may contain viruses and malware such as Ransomware, Trojans or Spyware. The same can also be valid for the browser changes imposed by the browser hijacker. Sometimes the newly installed search engine components, toolbars, homepages and buttons may make the browser unstable and even more vulnerable to potential online hazards.

That’s why the general advice we can give you if you have a program like Lnkr on your PC is to try to avoid interaction with its content as much as possible. And since this can be very hard, the optimal solution is to uninstall the unwanted app and permanently remove its components from your browser with the help of the instructions in the guide below.
