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

There are many forms of software that you certainly wouldn’t want to have inside your system – viruses, Trojan Horses, other malware like Ransomware or Spyware and so on and so forth. However, not all unwanted software is necessarily harmful or meant to be used in cyber-crime activities. There are also apps like that, while still regarded as undesirable, are rather harmless or at least not intended to mess up your computer.

If you are reading this, is most probably the reason why you have come to this post, in which case we should first tell you what this app really is. As we said, it is not a harmful virus or some malicious Ransomware or Trojan. It is, instead, a browser hijacker that gets installed onto browsers like Firefox and Chrome, altering their homepages, toolbars and search engines and spamming them with page-redirects, ads, banners and other annoying commercial content. This kind of activity isn’t necessarily malicious and is normally not going to damage your computer or compromise the software and files that are in it. However, it is bound to make it rather difficult and frustrating for you to browser the Internet. After all, getting randomly redirected to sites you didn’t want to visit and getting frequently big banners and ads on your screen when you are trying to reach a certain site or page is definitely not a pleasant experience. Due to this, pretty much all of the users who come to face such irritation seek ways to put an end to it as soon as possible so that they could once again use their browser in piece. If that’s the situation you are in at the moment, we may have something for you that will help you uninstall and regain control over your browser’s settings. Have a look at the removal guide that follows and if need be use the instructions that it contains in order to get rid of the annoying app.

It’s inadvisable to trust browser hijackers

Despite not being the most dangerous piece of software that can get inside your system, a browser hijacker is definitely not a type of software that we would advise you to trust or keep inside your computer. Obviously, it is annoying to have an app like around but note that keeping such software inside the computer may also be potentially unsafe in certain cases. While the hijacker will most probably not try to harm anything, know that the ads it is bound to spam you with may not always be what they may present themselves to be. This means that you may get shown fake ads or ads regarding overpriced low-quality products and you may get tricked into downloading even more unneeded and unwanted software. In many cases, the ads may even land you on sketchy, obscure, obscene and potentially unsafe sites. Considering all of this, it really is a better idea to eliminate the source of the adverts and the page redirects instead of procrastinating the hijacker’s removal.


Type  Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms Symptoms typically include  sudden page-redirects and nagging ads on your browser screen.
Distribution Method Typically, file bundles tend to be used for the distribution of hijacker apps.

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.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
