If you have recently detected an app named “Virus” on your computer and are concerned about your PC’s safety, make sure to read the next lines. This is not some sort of a nasty virus or a dangerous Trojan or Ransomware-based infection. Although “Virus” may behave rather aggressively when it comes to its ads and its redirects to different pages, the main purpose is different from the goal of most malware programs out there.

The security experts classify this piece of software as a browser hijacker. If you don’t know what exactly a browser hijacker is, on this page, we will do our best to briefly explain to you what the specifics of this type of software are and what to expect from it. In case that you are looking for an effective method that can help you remove “Virus” from your Chrome, Firefox or IE browser (or from any other browser) and uninstall the new homepage or search engine that it has likely added to it, know that we are here to help! Our “How to remove” team has prepared a detailed removal guide to help you remove the pesky app as well as a trusted removal tool for automatic assistance. Before you scroll down, however, let us tell you what exactly you are dealing with. “Virus” is an ad-supported application and its main function is aimed at displaying pay-per-click ads and sponsored page-redirects on your screen. Initially, the application looks like a normal browser add-on which promises to provide you with some free functionality. However, the moment it gets installed on the system, this browser hijacker sets some changes to your main browser and imposes some new search engine or homepage settings. Before you know it, your Chrome, Firefox, Explorer (or any other browser that you might be using) may start to flood your screen with various pop-ups, banners, blinking boxes, ads and page-redirect links.  As a result, you may not be able to use your browser normally and may constantly get interrupted by the sponsored promotional messages generated by the browser hijacker. Luckily, there is a way to quickly remove the unwanted ads and uninstall the nagging software once and for all. In the instructions below, we have listed all the steps that you need to take to effectively eliminate

How can hijack your browser? “Virus” is not some cunning malware infection. That’s why it cannot infect you in a stealthy way like a Trojan or a Ransomware virus. However, there are still many other methods which can help such a nagging piece of software to become part of your system. One of the most common distribution methods of browser hijackers is the so-called software bundling. This method allows the software developers of such apps to group and bundle different additional applications in one installer and to spread them as one.  That’s why it is very possible for “Virus” to get downloaded and installed into your system along with free third-party applications that you download from unreliable websites, torrent platforms, shareware pages, spam messages and ads. It can also come attached to pirated software and application updates or through spam or junk email attachments. That’s why, to keep your PC clean, you should always closely monitor the setup process of every new application that you install and specifically pay attention to any Advanced/Custom options that allow another application to make changes to your browser and to your system.


Type  Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Different pop-ups, banners and automatic page-redirects may disturb your web surfing.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

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. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
