This page aims to help you remove Fishjane “Virus”. These Fishjane “Virus” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Fishjane “Virus” is a type of software that demonstrates its presence on your PC by affecting your browsers – Chrome, Firefox, Explorer – and showing plenty of diverse ads (usually pop-ups, pop-unders, tabs, boxes and banners) on your monitor, once it has been installed on your computer. Some users find it among the most irritating software ever developed. In this article we will discuss how exactly your machine has ended up being contaminated with this program. To understand that completely, we have to clarify the type of the program and the distribution methods.

Fishjane “Virus”: type and distribution

Fishjane “Virus” belongs to the constantly growing group of ad-producing software. This group consists of Adware and browser hijackers. Normally, Adware is spread via various sources – sometimes these programs appear incorporated in a website, sometimes they may get to your machine through torrents and shareware. Other times Fishjane “Virus” could be distributed by spam emails and even text documents, however, the most typical way of spreading any piece of ad-generating software is within bundles. The so-called software bundles usually consist of a piece of Adware or a browser hijacker, as well as other programs, like games, for example. There are two reasons why developers might choose to spread Fishjane “Virus” around. The first one is that by combining it with the programs that they have themselves created the programmers can offer their bundle for free. The second one is that they could still distribute such bundles for free and make their own programs popular among users worldwide; while still being able to profit. The money usually comes from the displayed ads. This is an online marketing strategy, similar to any other ad campaign you have ever been exposed. This practice is NOT against the law of any country in the world, which leads us to the next important question about Adware…

Is Adware dangerous?

What we can state for sure is that this type of software could be particularly annoying. Sometimes the ads that it produces may be very hard to avoid. Sometimes they might even redirect you to websites that you find suspicious or strange. Sometimes their production could lead to a slowdown of your machine, due to the consumption of CPU and RAM by their campaigns. You may be able to find some more features that may seem shady to you – for example, you may notice that all of the generated ads match the profile of your current search requests. If you have been, say, looking for a new laptop online and your PC has been infected with Fishjane “Virus”, it will likely display only ads containing laptop deals. This feature is not necessarily negative, as you may really find the products and services you have been searching for at decent prices. However, such a research-based approach has only contributed to Adware’s questionable image and all such programs have been identified as potentially unwanted. Still, a potentially unwanted program doesn’t equal a malicious one. Fishjane “Virus” is NOT malware. If it were a type of malicious program, it would be capable of doing something evil to your system like encrypting your files and asking for ransom to grant you with a decryption key (as Ransomware does). It could also be able to explore your computer’s weak spots, like an outdated anti-malware tool or other program (like Trojans do). Maybe it would be the reason for the crash of your entire system. However, it cannot do any of the aforementioned typically malicious activities and you can be sure it is not a virus.

Many users might mistakenly think that Fishjane “Virus” could self-install on their machines and this is how they have ended up contaminated. However, no ad-displaying software can ever do that. Actually, users let such programs inside their systems by installing the software bundles they download in a wrong way. This might be your case as well. Maybe you cannot remember installing exactly Fishjane “Virus” on your PC, but this might come from the fact that you have been too excited to use a certain other piece of software from a single bundle and you have wanted to install it as quickly as possible. That’s why you have chosen what most users normally select as an installation method – the Quick or the Default option. Bear in mind that you shouldn’t do that, because this way you put all the content of the bundle in your computer. Instead, go with the other possible wizard feature – the Custom (or Advanced) one, which will allow you to choose the particular products you need from the bundle and install only them.
