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 been getting interrupted by annoying ads “generated/brought to you by” while browsing the web, then it is important for you to know that you are most probably dealing with a kind of potentially unwanted application from the adware type. This application is developed by a group of developers who promote it as a free tool which can enhance the users’ browsing experience. “Virus” can easily get added to browsers like Firefox, Chrome or Internet Explorer but if you cannot remember specifically installing it on your system, then it means that you have most probably allowed its installation while downloading and installing other cost-free software on your PC. Such distribution practices are known as software bundling and are often used for the distribution of adware, browser hijackers and other potentially unwanted applications.

Once find its way into your machine, the very first thing that it usually does is it changes the way your default browser behaves. Various modifications may take place in your Internet settings. For instance, you may notice that some unknown browser extensions, add-ons, and plug-ins have been added to your browser without your approval. However, one of the most obvious signs indicating that you are currently dealing with an adware is the appearance of hundreds of unwanted advertisements on your computer screen. Typically, these adverts are displayed in the form of suddenly popping-up messages, banner ads, in-text links and similar notifications. Once clicked, they may often redirect you to other sites where you may get tricked into downloading some software, installing some updates or purchasing products with dubious quality. Most of the ads may claim to help you save money during your online shopping sessions. However, you should be aware of the fact that it is not a good idea to click on every randomly displayed message that shows on your screen because, thanks to methods like malvertising, many hackers distribute threats like Ransomware, Trojans and other nasty viruses. That’s why, to avoid the risks of interacting with sketchy content, we advise you to uninstall and remove its ads with the help of the instructions below.

Why do ads appear on your PC?

Generally, the main purpose of the annoying ads displayed by “Virus” is to redirect you to third-party websites, which are seeking to increase their web page ranking, promote their products or services and gain popularity over the Internet. The goal of the adware isn’t to harm you or to corrupt your PC, thus, it is incorrect to categorize it as high-risk malware and to put it next to threats like Spyware, Trojans or Ransomware. Still, due to its irritating ad interruptions, many people prefer not to keep such software on the system and use manual instructions or professional removal tools to uninstall it and have its ads permanently removed.

How to prevent adware invasions?

In order to avoid the infiltration of such adware-type applications on your computer, you should start paying attention to each and every installation step of freeware and shareware applications and different bundles. For that, make sure that you follow the below-mentioned steps, which will help you protect your system from “Virus” or similar applications.

  • First, try to download software directly from its official website and avoid non-reputed software sources, spam, freeware, shareware, etc.
  • Second, read the EULA, the Privacy Policy and similar details, related to the program that you want to install.
  • Third, always select Custom or Advanced options for installing any apps.
  • Finally, uncheck any addition or recommended installs, which you don’t know.

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.
