This page aims to help you how to remove the Nefryhok Search “virus”. The Nefryhok.xyz “Virus” primarily infects Chrome users and redirects them to http://nefryhok.xyz/.
Nowadays there are more and more infections with browser hijackers. This is also the case with the program called Nefryhok Search. It is the root of the unusual behavior of all your browsers recently. No matter whether you try to load a webpage in Firefox, Chrome or Explorer, the browser just broadcasts some rather disturbing ads in huge numbers or redirects you to a completely different page from the one you wanted to open. In addition, probably the usual search engine and homepage of your browser has been substituted with new, completely unfamiliar ones.
How does Nefryhok Search act?
We have pretty much summarized the typical behavior of any browser hijacker above. Still, the reasons for such sometimes irritating activities might be unclear to you. If you are wondering why any program might be programmed to generate so many ads, the answer to that question is that the software developers profit from the invasive ads as easily as Nefryhok Search generates all those pop-ups, boxes, pop-unders and other versions of advertisements. The producers and developers of the promoted software, goods and services are willing to pay a great amount of money to everyone who offers efficient advertising. And expectedly, as the most widely used means of spreading information at the present moment is the Internet, they have turned to the people responsible for a great deal of existing virtual content – programmers. As a result, producers and developers now work together towards good promotional campaigns and all sides gain from such cooperation. The same is the case with the altered search engines and homepages, as well as with the annoying redirections. The creators of Nefryhok Search “virus” have been paid to popularize particular search engines and homepages, and if your browser has been affected by this hijacker, you will see those particular ones.
How does the infection caused by Nefryhok Search happen?
The means of distributing Nefryhok Search are directly connected to the reasons why such software has been developed. Programmers like to spread browser hijackers and other ad-broadcasting software by putting them together in a set with various other programs. Such sets of software are called bundles. They are usually free for the user who ventures into downloading them and typically contain some interesting new programs and games, as well as ad-generating products. However, an infection does not occur simply by downloading a bundle. It happens only if you install it the wrong way, which does not give you the option to choose what to install on your PC and which programs from a given bundle you want to leave behind. Those ‘wrong’ options are called either default, automatic, typical or quick. The correct option, which you should click if you want to have the chance of installing only the content of the bundle that you really need, will be called custom or advanced. By using this option of the setup wizard you will make sure you get to select what you are putting into your system.
If Nefryhok Search infects a machine, does it have malicious features?
Luckily, we can honestly claim that Nefryhok Search does not possess any malicious functions. Viruses are always very harmful. As an illustration of this statement, Ransomware is a “virus” is designed to encrypt some of your files and then demand ransom for “setting them free” and making them accessible to you again. Browser hijackers could never do such a thing. Other “virus”es, like Trojans, usually use a program or a system weakness to get inside your device and steal data, corrupt your webcam and microphone, record keystrokes, rob your bank accounts, etc. Again, this cannot happen with a browser hijacker. Despite their normally harmless behavior and effects, though, they can still behave questionably sometimes. Hijackers might review your current browsing requests and generate a whole new ad campaign based on your recent surfing activities. Also, the ads might be the reason your computer may become slower than usual, which could really be irritating. Some of the redirections this hijacker is responsible for may lead to websites with unfamiliar or suspicious content. The new homepage/search engine it puts on your browser might appear to be inefficient or totally useless. To sum it up, Nefryhok Search might become a cause of great annoyance, but it could not be the reason for any dangerous activity on your device.
