The reason why we have created the article below is the rising number of infections caused by a particular program lately. Its name is “Virus”, and according to the professionals in the field, it is a browser hijacker, used for “hijacking” all kinds of browser apps -Safari, Chrome, Firefox, Opera, by modifying their default settings such as replacing the homepage and search engine and making them constantly generate pop-ups, banners, tabs and boxes. Another of the functions of this program is to redirect you to websites you have never wanted to check out before. But don’t let the panic take over. The name of this ad-producing software family is the most bothering fact about the browser hijackers. Nonetheless, some of them may really act in quite a shady manner and this aspect of their behavior has earned them a questionable reputation.

Hijackers can be blamed for the never-ceasing, constantly appearing ads that may become an unpleasant issue when it comes to surfing the web. What’s more, they are the ones responsible for the unknown browser homepages you are currently using. What might concern you the most among their common features are the manners in which they, “Virus” also, can redirect you to suspicious and completely unfamiliar locations on the Internet. Despite all these rather annoying traits that prove that “Virus” is a browser hijacker, it is quite harmless as it may never cause any real damage to your device. Bear in mind that this is not a virus and you are not facing any kind of serious contamination. This program is just a piece of ad-generating software; it can’t modify any other settings of your PC, simply those of your browser apps. Also, it is NOT able to use any of your data, passwords or private credentials without your permission or for bad purposes like spying on you, stealing your identity or your money or harassing you in any other way. Still, it may show some quite unsettling traits such as keeping track of your search requests and analyzing them in order to define what kind of products you might prefer to buy/order. This is necessary for any hijacker, as such a program will later be able to broadcast only the pop-ups and banners containing deals which could appear interesting to you.

Hijackers exist because:

To really understand “Virus”‘s behavior, you should be aware of the reasons why such programs are developed and spread around on the Internet. The answer to both of these questions is simple – money. Some vendors may be really fascinated by the opportunity to promote their goods (software, services) online. That is why they might be willing to pay some particular programmers to develop programs like “Virus” with the aim to popularize their goods. The payment the programmers get in fact comes from the displayed ads. The more of them “Virus” displays, the bigger the amount of money its developers receive in return.

Distribution and installation tips:

The usual distribution method that programmers use is via software bundling. This process is simply the mixing of various programs of different kinds and distributing them together, thus giving the users the chance to download and use all of them completely for free. It is possible that the hijacker now irritating you has come exactly from such a software bundle. But despite the fact that programmers can spread bundles, they can’t make you install or use anything inside them. You are responsible for that and that’s why you should avoid the most common mistake users make:

  • While there is really no fixed prevention practice, there is a concrete way to get infected with “Virus” and it is very simple: install all the bundles that you download  in the easiest way: by never reading any EULA agreements and by incorporating their entire contents into your system. A contamination will be 99% sure to occur in case you choose the Default feature of any installer, as this option will land you a hijacker or similar program and all the ads it may broadcast.

In spite of that, if you are one of the people who do not really like being attacked by plenty of colorful ads and banners while using your browsers, you might consider choosing the Advanced installation feature instead. In this way you will be given the opportunity to install only what you truly want from any program or a bundle.

But now it’s time to remove “Virus”, so just follow the guidelines inside our Removal Guide below.

Detection Tool “Virus” Removal


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 ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press  (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



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 ComboCleaner
a professional malware removal tool.
