Virus is an undesirable app that looks like a regular browser extension, but is actually an aggressive browser hijacker that must be removed from every computer. Virus is known for spamming browsers loads of questionable ads and causing automatic page-redirects to obscure web locations.

A recently reported software piece called Virus seems to possess certain traits and features that lead experts to categorize it as a browser hijacker. Virus is likely to show intrusive advertisements inside the browser and redirect users’ browsing to different pages that the hijacker tries to promote in attempts to increase their traffic.

If your browser is getting swarmed by random ads, offers about different products, unexpected update prompts about software that you rarely have to update and if your browser is frequently getting redirects to sites with promotional content or any site in general that you did not want to visit, then you most certainly have some form of a browser hijacker on your PC.

A hijacker is an app different from viruses and malware programs like Trojans, rootkits, ransomware and spyware. It isn’t an inherently dangerous piece of software. However, it can mess with the way your browser functions and may even make changes to its homepage address, to its toolbar buttons and to its search engine. Usually, this could happen to any browser but the most common targets of browser hijackers are popular browsing programs – ones like Chrome, Edge, Firefox and Safari.

Also, as mentioned above, changes to a number of the browser’s settings are also likely to take place  as a result of a hijacker’s presence. And overriding those changes may not be possible whilst the potentially unwanted app is still present and active inside the system. For that reason, we have prepared a set of instructions organized in an easy-to-understand and follow guide manual that will show you hot to uninstall Virus. Additionally, we have added a tested removal tool to the guide for those of you who may require additional aid.

More facts about the apps of the browser hijacker family

Even if you don’t really mind the ads or if you are getting some use out of the hijacker (as unlikely as both of those cases may be), you are still advised to remove the app from your browser and system because there may be certain security hazards which may arise due to the hijacker’s presence on your computer.

Now, we are still not implying that Virus is some sort of virus or malware program similar to a Trojan horse virus or ransomware. That being said, though, due to the uncontrolled nature of the types of ads that get shown on your screen and due to the likelihood of getting redirected to some less-than-reliable web address as a result of the hijacker’s activity, it is simple better to not allow this piece of software to remain on your computer for any more time than it already has. As we said, the instructions on this page, as well as the recommended removal program should be more than enough to enable you to eliminate Virus and so we urge you to give them a try and clean your computer.

When the computer restarts in Safe Mode, click on Start in the bottom left corner of the screen and enter msconfig in the search box. Open System Configuration by pressing the Enter key on your computer and then select the Startup tab as shown in the image below:


You should see a list of startup items that are already configured to run when the computer starts. Remove the checkbox from any startup item that you associate with Virus or that has its manufacturer listed as “Unknown” or has a random name to stop it from running. Save your changes by clicking OK at the bottom of the window.

Then, return to the Start menu and choose Control Panel>>Programs and Features from the menu.

Make a thorough check of your installed applications for any suspicious programs, such as Virus, that you think may have brought the browser hijacker into your system. Look closely at the apps you’ve installed lately and remove any that you suspect are causing your browsing issues.


Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 

Launch the Task Manager by using the CTRL, SHIFT, and ESC key combination on your keyboard.

Then, click on Processes and check for any suspicious processes that might be connected to the activities of the browser hijacker you’re trying to get rid of. If a process’s name or activity catches your eye, just right-click on it and choose Open File Location from the shortcut menu that appears.


Drag and drop the files from that location to the online virus scanner below and perform a scan to see whether the process is harmful and should be ended.

    What is Virus? Virus is an unwanted software tool used for online marketing that is known for aggressively putting ads in the browser as well as changing the browser settings and causing sudden page redirects. The main distribution channels for are file-bundling and misleading browser notifications.

    If you have this browser-hijacking app in your system, the most likely reason for its presence there is the recent installation of some free program on your computer. Hijackers like are often bundled with other free software, and they get installed alongside such software by default unless the user takes the time to manually disable them in the settings of the installation wizard. Another way you could have gotten this hijacker is if you’ve given your permission to some site to show notifications in your browser. The requests for such permissions are often disguised or presented in a misleading way, which is why you may not remember when or how this has happened.

    How dangerous is Virus? Virus is potentially dangerous because it doesn’t allow the user to control the stream of ads and page redirects and this could lead to your exposure to unsafe online content. could also be dangerous because of the changes it makes in the system and browser.

    Most browser hijackers are able to alter the starting page of the infected browser and/or replace the default search engine with a custom, low-quality knock-off version of a popular search engine such as Yahoo or Bing. Such custom search engines are typically designed to specifically show sponsored search results rather than the most relevant sites and pages for the specific search. In addition to not letting you easily find what you are searching for, this could also lead you to visit unsafe and unreliable pages. In the worst-case scenario, the changes in your browser may land you on phishing pages or pages that spread malware under the guise of free programs or games.

    Considering all of those factors that could make dangerous, it is strongly advised that you remove it as soon as possible.

    How to remove Virus?

    1. You need to start by finding and uninstalling any rogue/potentially unwanted program that may be in the Programs and Features section of the Control Panel.

    3. You must also restore the regular Startup list, Registry, Hosts file, DNS, and Task Scheduler settings by revoking any changes made to them by the hijacker.
    4. Lastly, you must get rid of any unwanted or unknown extensions in all your browsers as well as clear the cookies, caches, and history of those browsers.
