This page aims to help you remove Koilk “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.
Koilk is an adware program, that presents itself as a helpful browser tool, but many users complain that this program is actually filling their screen with nagging ads, pop-ups, and banners all the time. We also found that this software tends to redirect the users’ searches and advertises not one, but many sites, different ads, links, pop-ups and new tabs. Such activity is surely irritating; moreover, the adware has the ability to affect many web browsers – including Google Chrome, Internet Explorer, Mozilla Firefox, Safari, Opera, and others. After integrating with Chrome, for example, this adware usually inserts some browser extensions and starts to initiate various redirects and aggressive ads generation. Removing the ads by closing them usually leads to the generation of more and the streaming has no end. That’s why the only effective solution to eliminating the ads invasion is to fully uninstall Koilk form the system. This is not as complicated as removing a virus, and fortunately, it does not require the professional help of a specialist. You can do it on your own if you strictly follow the instructions in the removal guide below, but before you do so, we highly recommend you familiarize yourself with the real nature of adware.
Koilk is not a virus but still, here is what it may cause:
Programs of the adware type are supposed to help you find the best offers and sales, prompt you to certain ads and land you on certain sponsored websites. Such activity is closely related to the online advertising industry and does not aim to cause you harm the way that a Trojan horse or nasty Ransomware infection would. However, by keeping adware like Koilk on your computer, you will soon begin to notice some dubious facts about this software.
Normally, adware is based on the pay-per-click model. This means that instead of providing you with some functionality, Koilk basically serves the needs of its owners, who try to generate income from the clicks of sponsored commercials and have the best interest to expose you to as many pop-ups as possible. What is more, in order to gain more information on what you like and to be able to prompt you to more relevant ads, the people behind programs like this may also collect information about your IP address, technical information for your computer, search history, and surfing. This means that while on your computer system, the adware may silently track you down and transmit some data back to its developers or other third party marketers.

Can you get infected with this program without knowing?
Potentially unwanted programs like Koilk are often installed without the knowledge of the computer user. You’re probably wondering how it can get inside your system without permission? In general, this app moves along with other free software or sharing software, and the only way to make sure you will not download and install it is to choose the right installation settings. Do not choose widely used default or standard settings – these buttons are a common trick of the creators of potentially unwanted programs to mislead the users to install some optional applications along with the software they desire.
This is because, usually, agreements to install such programs as adware, browser-hijackers, add-ons or plug-ins are hidden behind these options. If you do not want to give your approval for unwanted installations, you have to choose “custom” or “advanced” installation settings because they let you see what is included in the software package and reject those applications you do not want to install. So, to avoid unwanted apps, you just have to uncheck “I agree with installing […]” and so on. This is all you have to do to protect yourself from being invaded by Koilk and other similar software.
Now to remove it safely, please proceed to the instructions or scan your PC with the professional Koilk removal tool for fast and effective results.
