The current article is dedicated to a program called MyMacUpdater “Virus”. This software version has been labelled as ad-generating software, which could only serve the aim of displaying pop-ups, banners and other ads on your screen; redirecting you to various websites and putting unknown homepages and search engines to your browser apps.

Browser hijackers: some general details

Every software version that is considered to be a hijacker has been designed to act as a promoting tool. Actually, these ad-related programs work with that intention ONLY – to display a really big number of pop-up ads, tabs and/or banners; and to promote some new or not so popular websites/ homepages or search engines. The producers of the promoted goods; the facilitators of the advertised services; as well as the programmers behind these sometimes irritating browser hijackers are keen on spreading this software category.

The first two parties involved are normally the ones who pay the third party to create the most effective advertising programs. A hijacker is considered efficient because it is able to broadcast the biggest number of pop-ups and cause the most redirections. In this way it is believed that more of the advertised products can be purchased by the people who are permanently shown those ads; and as a result, the producers of the things to be bought are going to earn a lot of money. In expectation, every person, who is part of the ‘pay per click’ scheme, in reality DO benefit from it.

MyMacUpdater “Virus” and how it might spread:

Usually, you may find such irritating software incorporated into a contaminated website or a torrent, or as a part of a video/movie-sharing web page. Accordingly, once you go to or accidentally open any of them, you could catch the hijacker, which is lurking there. Even though it is most common for programs like MyMacUpdater “Virus” to come as components of software bundles. Virtually, the term ‘a bundle’ stands for different free software mixtures, which could get distributed on the web, and could include games, programs, apps, Adware and/or hijackers. More precisely, when it comes to such sets of various software there is nothing to worry about. Unfortunately, the ad-producing programs inside them might make you somehow doubtful.

One thing to remember:

The bundles that are mentioned above could include some really useful programs and apps, and you ARE REALLY ABLE TO use them for free, without catching the potential hijacker inside. You should just follow this basic advice – no matter what you install on your PC, always select the Advanced {or the Custom} wizard feature. Like that each detail about the bundle will be displayed and you will see which programs and/or features exactly you really want and install only them.

Despite the rather suspicious way of distributing MyMacUpdater “Virus”, it is not a virus:

In spite of the popular misconception, no browser hijacker is dangerous itself. Because of their sometimes shady features, these programs have been thought as ‘potentially unwanted’, however, they have not been considered malicious. In general, browser hijackers truly differ from the malware-related programs you may catch while surfing the web. For example, Ransomware and Trojans in their capacity of  hazardous malware can and tend to:

  • hack your PC without your informed or uninformed approval;
  • use a program or a system vulnerability of your system to invade it.

Following these, one of the most dangerous effects could be destruction of your data or modifying it; encoding files and requesting ransom in exchange for them; keeping track all your personal activities online and so on. Luckily, no hijacker like MyMacUpdater “Virus” has EVER been able to do anything like that. A program like this could just tempt you to install all of the features or the entire content of the software bundle it’s lurking in, and after that – just research your browsing history and show you the products and services you might indeed need or want.

MyMacUpdater “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 SpyHunter 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 SpyHunter
a professional malware removal tool.
