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

As reported by a lot of IT experts, the Nonck Virus is a program belonging to the Browser Hijacker category. Since you are reading this article, it’s quite possible that you are already aware of the symptoms of the Hijacker infection. The most prominent of those signs are many different sorts of intrusive advertisements (for example pop-ups, box messages, banners and so on) all over your screen and some potentially unwanted changes in the search engine or the homepage of your main browser. Obviously, the reason behind writing this article is to help individuals who want to remove the obstructive Adverts and uninstall the program that is generating them. Before we start, however, just know that there’s nothing to be worried about – the Browser Hijackers programs are fairly easy to handle so you most probably will effectively deal with the Nonck Virus if you follow the instructions below. Apart from our guide, we are going to also explain what is such software capable of and what dangers it may expose you to.

The Nonck Virus removal from Chrome and any other browser

nonck virus

The Nonck Virus will try to redirect your searches and spam you with pop-ups.

A typical reaction of most of the people who face a Browser Hijacker for the first time is to confuse it with a computer virus since the latter has become a common term for everything that could not work right with a Computer system. However, putting programs like Nonck, and computer viruses under the same categorization is not correct. First of all, computer viruses are nasty pieces of program code, designed for a particular job – some examples include monitoring, data damage and more. Some representatives of computer threats such as Ransomware, or Trojans could cause permanent damage to your data or your OS. A Ransomware cryptovirus is capable of blackmailing its victims of the access to their own files while a Trojan can easily steal your passwords or corrupt the system without your knowledge.

Ideally, you can now notice the contrast between the harmful capabilities of a computer virus and the nagging, but typically harmless Browser Hijacker. Despite not being a direct threat, however, you, as a user who is getting constantly bombarded with ads, pop-ups, redirects, and sponsored links, are probably seeking how to save yourself from the Hijacker and its disturbance. Unfortunately, numerous anti-virus programs will not take any action against identified Browser Hijacker programs for the fact that the latter are basically considered as legitimate ad-generating pieces of software. That’s why, in order to effectively uninstall the Nonck Virus and safely remove its ads, you may need to follow the instructions of the removal guide below or use the professional removal tool for fast automatic elimination.

Dangers related to Browser Hijackers

It may come as no surprise, but clicking on the Ads generated by Nonck is definitely a really bad idea. One of the biggest reasons why you should remove this type of software from your computer is the fact that such programs are capable of looking throughout the recent activity of your online browsing and determining things about your interests and lifestyle. The Hijacker may monitor your latest search queries, your bookmarks, the sites you visit, the things you like and share on social media, your location, language and other traffic data. All of this is, usually, done in your “best interest” in order to show only the most relevant Adverts. The problem is that sometimes, the pop-ups, links, and banners, displayed by the hijacker may turn out to be deceiving and misleading. For instance, you may come across ads with unrealistic discounts (the item’s actual price is frequently even higher than what it’s typically sold for) or even get redirected to completely different items and unfamiliar sites full of low-quality products, shady services, and software from unknown developers. That’s why the best course of action when facing a browser hijacker like Nonck is to remove it from your machine as soon as possible.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
