This page aims to help you remove the Ckk.ai Virus. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.


Ckk.ai is a Browser Hijacker that can modify your web browser’s settings without your permission. In most cases, Ckk.ai can replace the search engine or the homepage of your browser and redirect you to sponsored websites.


The Ckk.ai Virus will redirect your browser when you try to use it and it will display pop ups.

It’s hard to ignore an infection with this type of software. You’ll surely notice the homepage or the search engine changes Ckk.ai has probably imposed on your Chrome, Firefox, or Safari browser, along with the constant site redirects and the flow of hard-to-remove banners, pop-up ads, and on-screen notifications. The following article, however, will provide you with all the information you need about this program, as well as with instructions for uninstalling it from your system. Just read through the next few paragraphs and follow the steps in our removal guide.

Ckk.ai on Chrome

The main purpose of the Ckk.ai Browser Hijacker is to take control of your browser and ensure that every time you open it you get exposed to many different kinds of advertisements. Various pop-up messages, on-screen ads, and redirect links are put strategically on your screen to make it difficult for you to avoid them.

The developers of programs like Ckk.ai, Fuq.Com or Sigonews make money each time the displayed advertisements are clicked upon thanks to a popular online business strategy known as Pay-Per-Click. This type of online advertising strategy has been designed to serve the marketing industry and has nothing to do with viruses and criminal schemes. However, there is an explanation as to why the word “virus” has often been associated with Browser Hijackers.

First and foremost, it all has to do with how programs of this kind run on the computer and the tasks they carry out. Applications like Ckk.ai can be very annoying, especially when they impose changes on the user’s web browser without asking for approval. Other justified concerns have to do with the ads they display. With the rise of threats such as Ransomware, the number of malicious ads has grown proportionally, becoming the primary method of distribution for these viruses. Therefore, you can never be sure which of the many ads on display might have been infected with a malicious payload. A single click on the wrong pop-up or infected banner will often be sufficient to download the Ransomware to your computer. Therefore, avoiding interaction with random web ads would be the best way to prevent such infections. This may sound a bit extreme, but we really wouldn’t recommend taking any chances when it comes to the safety of your machine and we would suggest uninstalling Ckk.ai as a preventive measure.

As for how the Browser Hijacker infection may have occurred, there are so many ways you can land such software on your system that we can’t say for sure. But you have most likely downloaded it together with some other software in a software bundle. This is a popular technique used to spread potentially unwanted software because users usually download and install it without even realizing it. To avoid this, simply customize any newly downloaded program’s installation settings. You can do so by selecting the custom or advanced option in the installation wizard. This will allow you to see the bundled software in the given software package and remove it if it seems unnecessary.
