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

In case that you have recently detected an application called inside your Chrome, Firefox, Explorer or another browser in your system, then the first thing that has probably come to your mind is that you need to find a way to uninstall it as soon as possible. And this is understandable because, with its arrival, this application has probably set some new search engine or toolbar settings without asking for your approval and has replaced your homepage with some sponsored address. In addition to these strange changes, “Virus” has probably started to spam your screen with various banners, pop-ups and page-redirect hyperlinks which simply do not stop constantly prompting you to click on them and visit various websites, sales platforms and offers. Fortunately, these are not some malicious modifications caused by a nasty virus because the application that you are dealing with is a typical representative of the browser hijacker family. Yet, you will not be able to return your regular browser settings while the hijacker is in your system even if you reinstall the affected browser or change it with another one. That’s why, if you want to effectively get rid of the imposed changes and the nagging ads that “Virus” generates, you may need to follow some specific removal steps. But do not worry if you are not an expert because our article will help you to successfully cope with the annoying piece of software and remove it without any issues.

If you are facing a browser hijacker application for the first time, you should know that the representatives of this software category are basically tools of the online marketing industry which are used to promote different products, services and websites. These applications are basically harmless and cannot corrupt your OS like a Trojan Horse or do something bad to your data like a Ransomware virus. Yet, they can be very annoying because they specialize in generating and displaying hundreds of promotional materials within your browser (such as ads, banners, pop-ups and others) and often tend to automatically redirect you to certain sponsored pages without your direct approval. The people who benefit from this activity are the manufacturers and distributors of the advertised goods because they gain exposure, traffic and potential customers and buyers. In fact, they pay the developers of hijackers like to display their ads.

Rewards systems such as Pay-Per-Click are often employed as they generate income based on how many times the users click on the sponsored messages which the browser hijacker displays. In pursuit of greater profit, the developer of browser hijackers typically d everything in their power to gain as many clicks as possible. That’s why they oftentimes use methods and tactics that involve placing changes inside the browser (homepage or search engine replacements, sponsored toolbars, redirect buttons, etc.), automatic page-redirects and aggressive ad streaming all over the screen.

However, this approach of online promotion usually causes well-justified concerns both in ordinary users, as well as in security professionals. After all, although the browser hijackers are not identical to threats like Ransomware, Spyware or Trojans, the changes they impose may lead to unwanted browsing interruptions, exposure to aggressive or misleading commercial content and unfamiliar web locations, as well as modifications in the search results. For these reasons, most experts, including our team, advise you to uninstall applications like from your PC.

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.
