System Jump targets Mac

System Jump is regarded as a type of a browser hijacker. Threats like System Jump are known to cause different problems like changing of the user’s designated home page or even the preferred browser of choice.

An application like System Jump is, obviously, an unwanted piece of software. It may enforce many undesired changes to your favorite browser and totally take control over your web surfing by initiating automatic page-redirects and aggressive generation of ads, pop-ups and blinking boxes of various kinds. But how dangerous a Browser hijacker can really be? Frankly speaking, the answer to this question may vary. Generally, the nature of most page-redirecting and ad-generating applications is not malicious and, therefore, despite the fact that many users may refer to them as “viruses”, they don’t really fall into this category. There are some major differences in the way Browser hijackers and the real malicious applications operate.

The SystemJump App

System Jump is a browser hijacker type of a security nuisance. System Jump App is categorized by the website redirects and pop-up ads it causes but it could potentially lead to even more serious problems.

Typically, the hijackers are tools created for online advertising. They are not meant to cause damage to the computer, to steal sensitive data, to corrupt the OS or to encrypt your files. A threat like a Trojan horse or a Ransomware virus, on the other hand, will not spare your machine and will leave it heavily damaged. Another major difference is that the hijackers are usually legitimate pieces of software which are distributed and employed by various online-based businesses. Malicious viruses like Trojans, Spyware and Ransomware, on the other hand, are created by cyber criminals who use them to break the law and to cause harm to the infected computers. The crooks usually hide their threats deep inside the system for as long as possible and try to block your security software from detecting them. In contrast, an application like System Jump won’t really try to hide its presence – quite the opposite, it would try to get in your face as frequently as possible. Still, despite being relatively harmless, the presence of the hijacker may lead to certain issues which is why most of the users prefer to uninstall it from their computers.

What is System Jump?

System Jump is categorized as a browser hijacker by security experts. System Jump is known to cause browser redirects and different pop-up advertisements in addition to security vulnerabilities.

The hijackers are definitely not as harmful as Ransomware viruses or a Trojan horses. However, they are certainly not desirable on the users’ machines because, more often than not, their presence may cause significant browsing disturbance that could make one’s online experience rather unpleasant. The main goal of System Jump and the applications of this kind (Default Products, Pronto App) is to serve the online advertising needs of its creators. Therefore, all of its focus will be directed at landing you on sponsored ads and promotional pages regardless of your actual search queries. As a result, you may often land on sites that you never had the intention of visiting or bump into inappropriate popping-up messages, misleading links and nagging banners. Some hijackers may also try to extract some browsing-related information from the users in an attempt to determine their interests and to later spam them with targeted ads. All in all, having a piece of software like System Jump on your PC may not be the nicest of experiences which is why, if it is causing you disturbance and irritation, you should not hesitate to uninstall it. Feel free to use the instructions in the Removal Guide below for assistance or run a scan with the professional removal tool on this page if you don’t have a reliable removal tool of your own.

For future protection, we advise you to stay away from the potential sources of hijackers which normally include spam emails, free download links, different software bundles, automatic installation managers, some software updates, torrents or attractive social share ads.

Detection Tool

Remove System Jump Mac App


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.
