How to remove Koilk from the computer and browsers

Today we'll talk about a dangerous program, called Koilk. We'll represent to you its strong and weak spots, as well as the ways to uninstall it forever. Here you will discover safe and convenient manners to eliminate Koilk from the device and from all modern browsers: Internet Explorer, Opera, Mozilla Firefox, Google Chrome and Safari.


Koilk surely is the most irritating and dangerous advertising tool of the latter month, and if you've experienced it these days – we're offering help. First and foremost, you should know that such sort of infection isn't like the genuine viruses, as it isn't a virus, actually. It’s a utility, made for a single purpose: to spam ads. As a matter of fact, the Koilk's purpose is more complex: it has to display ads and performs it in such an annoying way that user will click on an ad while closing it. Our guide will make it clear to you how exactly web-criminals get their benefit from Koilk, how it penetrates the PC and how to eliminate virus.


Koilk adware

What is Koilk. Removal reasons and methods

Swindlers, or whoever runs this advertising program, wanted to make it as annoying as nothing else before, to trick you into clicking on banners. Each click allows new adware into your system. From hackers' point of view this manner is too good to be true. Koilk simply shows a plethora of links, pop-ups, banners and ads, and because they appear right in front of customer's eyes, he wishes to remove them. Unfortunately, these banners can't be closed. There is no "hide" service for them, so every single click launches another tab or a separate window with a suspicious website. Except that, it may initiate a download of a viral file, so if the PC is already infected and the browser settings are spoiled – the file will get into it. That’s the way you get new adware while Koilk works in the system.




To get how the computer is getting cluttered with dangerous tools you should figure out how Koilk penetrates the computer. The word is the bundled installation. It’s literally the safest manner to penetrate the one’s laptop. Fraudsters usually put the malicious file on several websites and temporize, until operator downloads it. As soon as it happens, it’s a matter of chance, and swindlers can only expect that the operator won't read the EULA and won’t try to understand what he’s actually downloading. If you want to escape the penetration via bundled download – these hints might be helpful:


  • Do not use utilities, which hide their aims;
  • In any case, do not put off your antivirus, especially if a suspicious pop-up offers you to;
  • You should abstain from installing any utilities from suspicious sources;
  • Pay attention to the license agreement;


Now, when you know the essential rules of system safety, let’s explain how Koilk functions, for you to see the manners to eliminate it.


When the protection is passed, Koilk becomes very busy, which consists of adding unwanted registry strings, altering the browser settings, changing the features of browser tag marks and scheduling tasks. We can't be sure that the procedure is the same each time, but the browser controls are an intermediate goal for an adware, to make sure that your device is assailable. Usually, undesired tool goes for the start page and the pre-set search settings so that instead of the customary Google page you see the swindlers’ page. Each time you use it for Internet-surfing – you sacrifice the system to the hazard of being penetrated once more. Firm advertising utilities also establish scheduled tasks for reinstallation after deletion. This function makes it nearly impossible to get rid of them totally. You can try times and times again, removing unwanted files and folders, but as soon as you reboot the Koilk will be alive and kicking. If you're not happy about this scenario you should execute a deeper scanning or use a decent antivirus program.
