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

It’s likely that you’ve already had to deal with browser hijackers before, but if this is your first time landing one – it’s important not to panic. First and foremost, you haven’t been infected with a virus, so you don’t have to worry about your system being compromised or damaged in any way. Here, we will be looking at a particular browser hijacker known as “Virus”, whom we’ve been receiving numerous complaints about from our readers. Just as nay browser hijacker, this one will integrate with your Chrome, Firefox or other popular browser and will establish its own settings within it. Thus, with the installation of this program on your PC, you will immediately notice a change in your browser’s usual homepage, and a new default search engine will now be redirecting your searches to various unnecessary pages. Well, as pointed out, there’s nothing to worry about here. We have prepared a removal guide to help you deal with this issue in a quick and effective manner, but do read through the information provided here, as it could prove useful in the future. and its purpose, functions and consequences

Browser hijackers are primarily there to expose you to various kinds of online ads: popups, banners, box messages, links, new tabs, etc. All of these serve the purpose of promoting given services and products. The main goal of the developers behind programs like “Virus” is to get you to click on as many of these advertisements as possible. Their business is essentially based on strategies like the Pay-Per-Click scheme or PPC, which enables them to profit, based on the amount of clicks these ads receive. It’s a very lucrative online business model and you would be surprised just how many companies you know of actually benefit from it. However, in their chase for more and more revenue, the developers have also come up with a sneaky tactic of gaining more clicks. Very often, programs like will be able to monitor your browsing patterns and record the information that is of interest to them. Particularly, they would most be likely to take notice of your search queries, the list and frequency of visited websites, the kind of content you like, post and share on social media platforms, etc. All of this gives the program the needed insight into your personal preferences and it sort of creates a profile of your interests. As a result of this, the ad flow will be tailored to your profile, personally, so as to ensure that more ads actually attract your attention and hopefully – your clicks as well.

Now with that out of the way, let’s clarify the point of virus association. If you’ve researched the topic already, it’s more than likely that you’ve stumbled across accusations of being a virus. These are fundamentally incorrect. You cannot compare a program, whose sole aim is to generate ads, with malicious software like Trojans, ransomware, worms, etc. These are all very dangerous programs, capable of inducing irreversible damage. As for browser hijackers, the worst you can expect from one is to make your computer work a tad slower. Due to the fact that this software calls on your PC’s resources to produce the numerous popups and banners, it could very well take its toll on weaker and/or older processors. This could be reason enough already to want to remove the hijackers, but it’s not something life-threatening to you or your machine.

Distribution techniques and other hijackers mainly rely on program bundles to get distributed and installed on people’s computers. By bundling a hijacker with other software, the developers basically attach it to that other program’s installation manager. So, when you decide to download a new program (typically from a file sharing website or other open source download platform) and then install it, you can overlook the added content and simply install everything that’s in the bundle. Avoiding this is beyond simple so be sure to remember how this works. Always adjust the installation settings manually by selecting the advanced/custom setup option. This will allow you to see what other programs are included in the bundle, if there are any. Furthermore, you will be able to remove any of them that seem suspicious or otherwise unwanted. Simply deselect the checkbox beside the ones you don’t want to install and proceed with the next steps of the installer.

      • Yes, I`ve followed this “If you are a MacOS user, please follow this guide!”, but did`t work. There were no extensions, I did everything but nothing happens …:(

          • Can you find those files on your device? What were they? Did you try re-installing Chrome?

          • Yes, I reinstalled Crhome but this (@#$$%$%) remains the same!! I really don’t know what to do since Safari is my default brouser but some features only work in Crhome ( like banks applications).
            I’m afraid of putting on my accounts an passwords since this “virus” installed.

  • You can try having it removed and see if anything changes. However, it is up to you. It also depends on the type of adblocker you are using.
