QSearch is a browser hijacker that is designed for Mac devices only. The most often attacked are web browsers like Google Chrome, Mozilla Firefox, and Safari. But, a potentially unwanted program like QSearch also could also appear on other browser applications.


The QSearch Virus will make undesirable changes to your browser

The majority of web users are aware of the danger that threats such as Trojans, Ransomware and computer viruses represent and know that they should keep their computers safe from such pieces of malware. Many people, however, lack understanding of the purpose and the abilities of apps like QSearch because these pieces of software do not fall under any malicious category yet, at the same time, are regarded as potentially unwanted. Such applications are usually classified as browser hijackers and they won’t typically harm your system. Still, they can be extremely annoying because they can totally take over popular browsers like Safari, Chrome, and Firefox and fill their tabs with invasive ads, hard-to-remove banners, pop-ups and page-redirect links as well as impose custom and low-quality search engine tools and homepages.

What is Q Search?

Q Search is a browser hijacker type of a mac app that can appear on a variety of Mac browsers like Safari and Google Chrome amongst others. The ads aggressiveness and the constant browsing redirects are an obvious reason why many web users would prefer to uninstall Q Search and remove its imposed changes.

However, there is also another problem related to this type of software, which many people may neglect and that is the quality and the safety of the randomly displayed ads and websites redirects, which the browser hijacker may display.

The truth is that, regardless of how good-looking and attractive the pop-up messages may appear, not all of them may be as safe as they look. Fake ads and malicious links may easily sneak inside the content that QSearch “Virus” typically generates and if you click on something like that, you may accidentally get redirected to shady web locations. Threats like Ransomware, Trojans and various other nasty viruses frequently use the help of malvertising ads in order to spread across the web and to infect more potential victims. That’s why it is best to stay careful around browser hijackers like QSearch and make sure you uninstall their sponsored browser components and redirect links with the help of the instructions in the removal guide on this page.

How To Remove QSearch from Mac

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.
