The information below concerns all the users that have been infected with “Virus”. In general, this piece of software has been classified as a browser hijacker. In case you have never heard or read about this term, the programs associated with it may have the ability to infect your computer in quite a tricky way, however, they affect only your PC’s browsers, including the most popular ones, such as Safari, Firefox, Chrome and Opera. After your computer has been infected, the browser hijacker tends to modify your browsers in several ways. For example, it may cause a a great number of possibly unwanted pop-ups to appear every time you try to open a website. In addition, the browser homepages and search engines you are used to seeing might be replaced with new, often totally unfamiliar, ones. Also, while you are browsing, you might experience some sort of a redirecting process. It is possible that you could be sent to web pages, which you never intended to visit. In short, these are the main characteristic features of any browser hijacker you might come across while surfing the Internet. All the details about these programs will be discussed and elaborated on below.

Could hijackers actually “hijack” anything on your PC?

Despite the annoying redirecting and the even more irritating banner and pop up ads, and all the other browser hijackers are mostly harmless programs, which have been created with the sole purpose of promoting various kinds of goods, apps, programs and web pages. In fact, their creators get incredibly generous payments from the people, who need to advertise a product of theirs online. What’s more, (and most of all the other hijacker versions, too) could NEVER access anything on your computer besides the browser apps and their search request databases. No other files are available to them and they cannot harm your system in any way.

Should one expect anything dangerous from

As we have mentioned in the previous paragraphs, no harmful or malicious activities could ever come from a browser hijacker. Nevertheless, some of its characteristics could be seen as slightly suspicious. For instance, if can access your browsing history records, it could build its new advertising campaigns and redirecting processes according to the data related to your most common search requests. This is neither illegal, nor is it dangerous; however, some users could still regard it as a little too shady. Also, another rather shady habit of most hijackers concerns the way they get distributed. Logically, no user will ever directly agree to install such an irritating program on their computer. As a result, browser hijacker developers should be extremely creative and cunning in order to spread their annoying programs legally. This way of distributing software includes tricking the victim user into unknowingly approving the installation of, for example. Generally, this could be achieved by mixing the Adware and hijacker programs with new and interesting apps and games, and forming so-called program bundles. Afterwards, such bundles are usually accessible to all users on the Internet for free and many of them download such mixtures from various file-sharing platforms. However, the download process doesn’t mean an infection. Choosing to install such a bundle via the wrong installer option does that. The installer options most likely to install the entire content of any bundle on your PC are usually named: “Default”/ “Automatic”/ “Quick” or “Easy”. All of them should be avoided to ensure that no ad-producing program gets incorporated into your system together with other, otherwise useful, programs. Most importantly, make sure that you always go with the appropriate wizard choices, which are normally called CUSTOM and ADVANCED. Selecting such an option authorizes you to control the entire installation process and allows you to include and exclude programs and their features.

How could you be sure that is not a virus?

Actually, we are certain that you are not dealing with a virus, because viruses have distinctive harmful features. To be completely precise, you are dealing with a potentially unwanted program, which differs greatly from the usual viruses such as Trojans and Ransomwares. Any Trojan or Ransomware installs itself automatically on your device and then accesses your entire system. Knowing even these small details, you can logically conclude that in no way resembles any known virus.

Is the removal of such a program a possible process?

Actually, it is, especially in case you choose to use a detailed guide prepared by experts. Such a Removal Guide is available at the end of this article and can be used for free.

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.
