Mac Security Plus

The ads generated by an application called Mac Security Plus have recently triggered many complaints from a big number of disgruntled users. However, despite this app being quite unpleasant to have on your PC, know that it isn’t really a virus or some sort of a nasty Trojan or a Ransomware infection. Mac Security Plus is a legitimate software piece which has been categorized as a browser hijacker compatible with Safari, Chrome, Firefox and other browsers and which seeks to boost the visits and clicks to certain advertising platforms by making unauthorized modifications to the browser’s starting page address, toolbar and search engine. This article explains how Mac Security Plus works and when the “ads generated by Mac Security Plus” may become a problem.

You can easily find browser hijacker applications like this one the Internet, inside different free download links, spam messages, ads, etc. As already mentioned, these applications are known for displaying content such as, page-redirects, banners, articles, videos, blogs, intrusive links to other sites. In order to advertise more effectively, however, they typically integrate with the main browser in the system (it could be Chrome, Firefox, Explorer, Safari, etc.) and directly install some promotional tools, buttons, search engines or homepage domains, which are normally linked to their partners. If you’ve already noticed similar changes in your default browser or you have started seeing an increased number of banners, pop-up ads and similar content all over your screen, the chances are that you most probably have a browser hijacker installed in your system. Now, such software is generally not malicious and could easily be removed if it starts to cause trouble. However, in order to safely uninstall it, you may need to follow some specific instructions or use a professional removal tool. Mac Security Plus “Virus”, in particular, can be effectively eliminated with the help of the steps in the removal guide below and we highly recommend you use them if you want to save yourself from this application.

As a matter of fact, the content generated and promoted by browser hijackers should mostly be legitimate (though nothing can guarantee this) and you have nothing to worry about. However, one thing that commonly bothers some of the web users is the fact that, somehow, such applications always know what exactly you are looking for and find a way to display appealing and interesting offers which seem to be related to your latest online searches. The secret behind this activity lies in the so-called traffic data collection. Apps like Mac Security Plus, for instance, commonly use different tracking cookies to learn more about the users and to, in turn, show them relevant content. They may oftentimes collect browsing-related information such as IP addresses, clicks, browsing history and more, in order to analyze it and to display ads that are matching your interests. In most of the cases, thanks to this service, you may find offers that are actually useful, but we must remind you that third-party ads may sometimes also be dangerous and may expose you to unreliable web content and viruses. That’s why our advice is to be careful with where you click and make sure you remove and uninstall any unwanted or shady components from your browser because hidden threats such as Trojans, Rootkits and even Ransomware may hide behind various attractive messages that some hijacker-like applications may spam you with.

Detection Tool

Remove Mac Security Plus “Virus”


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.
