[ratings] “Virus” is a application that hijacks browsers such as Chrome, Firefox, IE and makes them operate in a modified way. It usually forces the browsing programs to show modified search results, ads, pop-ups, banners and new tabs every time the users open a new browsing session. Apart from facing various annoying advertisements, people whose browsers have been hijacked usually have to deal with a newly set homepage domain, a new search engine or a toolbar, which initiates page redirects to certain sponsored websites and platforms.

Since “Virus”spreads mostly via software bundling, many computer users do not even notice how this application might have gotten installed on their systems. Therefore, the changes that it initiates often come unexpectedly and cause a lot of irritation and disruption to the normal web surfing.

Fortunately, there is a quick and easy way to have all these changes reverted and ,in the next lines, we are going to show you how to do that. Our “How to remove” team has prepared a detailed Removal Guide with exact instructions so if you want to bring your favorite browser back to normal, stay with us and read the next lines.

What kind of a application is “Virus” and is it dangerous?

According to security experts, “Virus” can be categorized as a browser hijacker. Now, a browser hijacker may sound like a very scary term to those of you who are not familiar with the nature of this type of software. However, despite its scary-sounding name, such software is generally not harmful and does not typically initiate any criminal or illegal activities on the targeted computer. Unlike a real virus (such as a Ransomware or a Trojan horse), an application like “Virus” is not developed with malicious intentions and its purpose is normally simply to advertise something and not to corrupt your system or encrypt your files.

This application usually tries to show ads and sponsored search results in an attempt to generate profits from Pay-Per-Click campaigns. It may also redirect you to different promotional or partnering web pages or modify your default browser settings with the same purpose. However, in most cases, a hijacker should not be able to steal your data, hack your software or initiate any type of criminal activity.

Uninstall “Virus” from the system

In order to secure their presence on your PC, most of the browser-hijackers install additional plug-ins or add-ons that help them remain in the system. Their detection and removal may be a bit difficult. Therefore, we advise you to remove “Virus” automatically, by using professional removal security software. If you don’t have such software, you can download it from this page and you can also follow the manual removal instructions in the guide below if you’d prefer a more hands-on approach. Also, to complete the removal, you must reset your browser settings. To that end, we have prepared detailed instructions for the most commonly used browsers. You will find the instructions down below.

Still, there might be some issues and risks which you should bear in mind if you have “Virus”on your PC. For instance, some of the ads, which the browser hijacker may generate may land you on dubious web pages or intrusive websites which might even be unsafe. That’s why, it is a good idea to keep in mind that there’s always a risk of landing on some sketchy page and thus have your PC exposed to dangerous content. You never know which of them may be safe and which may lead to infection with dangerous viruses such as Ransomware, Trojans or Spyware and other nasty computer infections.

Another thing, which may add up to the browsing disturbance is the data tracking process that the browser hijacker may launch in the background of your system. may try to monitor your online activities and collect information related to your surfing. Even if the developers of the application may claim that most of this information is classified as non-personal, they may still use it to learn about your interests and then try to expose you to targeted ads.

The best way to guarantee your privacy and to make sure that your system is safe is to simply uninstall the browser hijacker. This will also take care of all the annoying ads, pop-ups, search engine changes and toolbars and will permanently remove them from your PC.

Techniques used to spread hijackers

Most potentially unwanted applications, including browser-hijackers such as, sneak inside the system thanks to our careless online behavior. Users typically rush through the installation process of new, download applications from unauthorized developers and click on unreliable ads. Still, the most common way potentially unwanted applications get installed is through the installation of free apps and software bundles. Browser-hijackers are often grouped with other regular applications, free programs, games, optimization tools or browser extensions and come in one setup. The thing is that the information about their addition to the setup is oftentimes not clearly not disclosed in the Quick/Recommended setup settings, which are the most popular installation method. Because of this, users who choose these settings don’t realize that there’s anything added and cannot opt out of the installation of the browser-hijacker. If you want to avoid potentially unwanted applications, however, you should choose Advanced or Custom setup settings. Tat way, you will be able to easily leave out anything added that looks potentially unwanted from the installation by unchecking its pre-selected checkboxes.
