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

In this article we are discussing the possible reasons why a web page redirecting software famous as JS.Webcoinminer may target your browsers (even Firefox, Chrome and/or Explorer), and is, because of that, identified as a browser hijacker. This infection would mind cryptocurrency without the user’s permission. Furthermore, we are thoroughly going to explain to you all the common features that characterize this sort of redirects. Some of their usual effects that are worth being mentioned are their ability to generate plenty of possibly irritating online ads, to make your browsers load websites you have never really meant to open or to put some really unfamiliar homepages (or search engines) on your browsers, no matter which browsing program exactly you use on your computer.

What’s more, we are sharing some prevention advice to make it clearer to you how to avoid such annoying pages, right after you have successfully dealt with the ongoing infection. For the easy and successful process of removing this annoying redirect we have come up with a simple yet detailed Guide available below.

JS.Webcoinminer- essential details:

JS.Webcoinminer is a kind of a page-redirecting software that falls into the hijacker category, a fact that to some extent explains its typical behaviour. Such redirects could indeed be capable of causing some unwanted changes to the browser apps you have installed on your device and the way these apps look and function.

Maybe you have already concluded from the term used to describe those undesirable software pieces that their versions may be able to make some modifications to your browser’s settings. These changes might result into the broadcast of lots of cyber ads; and into the authorizing of some bothering redirection processes. What’s more, the display of some unknown search engines/homepages is also possible. Generally speaking, the browser hijackers we know of are usually NOT that harmful and greatly differ from any known kind of a malware virus.

Are browser hijackers similar to famous malware viruses such as Trojans or Ransomware?

It may be true that browser hijackers may really top the list of the most annoying types of software you could ever catch on the Internet. However, they are NOT really close to any virus-type program due to the fact that they usually do not have any really dangerous features.

Here, we will explain the differences between the common forms of malware and this kind of advertising tool:

Real malware versions the likes of Ransomware or Trojans can infiltrate your PC, damage your system or lock up the computer and the files that are on it for the purpose of blackmailing you afterwards for the restoration of your system and files to their previous state. One more characteristics of the popular kinds of malware, including any Trojan-based virus, is their ability to constantly spy on you and track all your activities, in case the virus has infected your system. Another even scarier aspect is that all these malicious activities might be so subtle that you might not really notice the virus until it becomes clear it has caused some serious damage like, for example, an identity theft.

Pretty much representatives of the family of the browser hijackers have ever presented such capabilities and malicious effects. So – remain cool!

How does a typical hijacker-caused infection process take place?

The potential methods of spreading JS.Webcoinminer are usually in relation with the reason why such pages are introduced in the first place:

Programmers may distribute browser hijackers and other forms of ad-related software by incorporating them into bundles with many other kinds of software, apps and games. Generally, such software bundles are available free of charge since their designers are normally paid for the ads a hijacker could later display on your screen.

However, most hijacker contamination won’t just happen as a result of the act of downloading such a bundle. This sort of infections might only occur in case you ignore the installation settings of the bundle. Because of that, if you do want your device to remain hijacker-free and to have the chance to install only the components of the bundle you really need, it is NECESSARY that you CHOOSE one of these installation features: the Customized, the Custom or the Advanced one. Using any of those will allow you to see the optional added software and leave out anything that could be potentially undesirable or simply not needed.

Our Removal Guide published here might be your solution provided that an already ongoing hijacker infection is bothering you. Simply make sure to implement the instructions there carefully and accurately!
