MacSecurityPlus Virus (Mac)

What is MacSecurityPlus?

MacSecurityPlus is an adware-type application that people usually download and install unintentionally. Once installed, it tracks (records) users' browsing activity and displays various pop-ups ads. It also prevents users from closing the Safari and Google Chrome browsers - it reopens them when they are closed. We strongly recommend that you uninstall this application immediately.

When MacSecurityPlus is installed, it displays a fake system window stating that the Mac computer is low on memory and suggests users free-up memory by closing opened/running applications. The pop-up window hides another window beneath it, a system window in which the MacSecurityPlus app requests permission to control the Google Chrome or Safari browser.

This is to gain access to documents and data stored on the browser and perform various actions using it. By closing the previous pop-up window, people are tricked into clicking the "OK" button on the hidden window and involuntarily giving permission for MacSecurityPlus to control the browser. It also displays these windows when users try to delete it.

We have provided instructions about how to remove this adware-type app below. Other problems with having apps such as MacSecurityPlus installed are display of pop-ups ads and tracking of users' browsing activity. Typically, ads displayed by adware are annoying and conceal underlying content of visited websites.

People who click them are usually redirected to various untrustworthy, potentially malicious websites. Some of these ads might be designed to run scripts that download and install even more unwanted apps. Furthermore, apps such as MacSecurityPlus collect IP addresses, entered search queries, URLs of visited websites, geolocation and other browsing-related data.

It is very likely that developers share all gathered information with third parties who misuse it to generate revenue. Note that some of these people might be cyber criminals.

Adware-type apps are often presented as 'useful', however, when people download and install them, they start to experience various problems such as information tracking, pop-up ads, and so on. Having these apps installed often leads to unwanted websites and rogue installations. Therefore, remove all adware-type and other PUAs immediately.

How did MacSecurityPlus install on my computer?

People install unwanted apps (including adware) through intrusive advertisements or when software developers use the "bundling" method. Bundling is a deceptive marketing method to trick people into downloading and installing unwanted applications with other, regular software.

PUAs are usually hidden in "Custom", "Advanced" and other similar sections of regular software set-ups. Information about the inclusion of PUAs is not properly disclosed. Furthermore, many people download and install software without changing/checking available setup options, thereby unintentionally allowing PUAs to also be installed.

How to avoid installation of potentially unwanted applications?

To avoid having PUAs installed, download software from official and trustworthy sources an avoid using third party software downloaders, installers, Peer-to-Peer networks such as torrents, and other similar channels/tools. Check all "Advanced", Custom" and other settings that are available in the software setup.

Inspect all checkboxes (especially those ticked by default) and dismiss offers to download or install potentially unwanted applications. Do not trust intrusive ads - once clicked they can redirect to untrustworthy websites such as gambling, pornography, adult dating, and so on.

If you experience these ads and redirects, check for new and unwanted plug-ins, add-ons, and extensions installed on your browser and remove them immediately. If your computer is already infected with MacSecurityPlus, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
