Today we are going to show you how to remove the “Your computer is low on memory” virus on Mac. While the operating system and third-party software are getting updates, the hardware is not upgraded in general. Ultimately, it means that the computer will be unable to smoothly handle increasingly heavy applications at some point.
Why do you see the “Your computer is low on memory” virus on Mac
If you are seeing a pop-up saying, “Your computer is low on memory” on your Mac even though it is equipped with the latest components, there might be a virus in your computer.
In fact, pop-up alerts indicating that a Mac is running low on available memory have been a warning sign of adware and scareware activity for quite some time. Also known as potentially unwanted applications (PUAs), these viruses accumulate throughout the host system by displaying different types of sponsored information and misleading pop-up dialogs.
The goal of generating ads on the victim’s web browser is to gain profit through pay-per-click and other commission-based marketing methods. Meanwhile, the motivation of cybercriminals behind displaying fake system maintenance warnings may seem vague at first glance. It becomes clearer once you take into account some additional features of malicious optimization software and adware.
One of them revolves around the cross-promotion of the associated threats, where the unsuspecting victim is tricked into accepting the shady installation by clicking on a hidden button like anything else. The only button the user can press in the fake alert under scrutiny says “Close”, but in reality, it may resort to arbitrary commands such as extracting another PUA without being detected. Adware programs known to trigger “Your computer is low on memory” Mac notifications include Spaces.app, ScreenSaver.app and ScreenCapture.app.
Fake maintenance software is yet another form of malicious code that takes advantage of the low memory shortage on the Mac. It does so to draw the victim’s attention to the supposedly unsatisfactory performance of the host computer. In addition to the puzzling message “Your computer is low on memory,” the pop-up also says, “To free up some memory, close some applications.” The average Mac user’s natural response to such a dialog is to take a look at current CPU and memory consumption to see what is consuming the most. Oddly enough, however, there is nothing out of the ordinary showing up in the Activity Monitor, and memory usage does not appear to exceed any reasonable threshold.
This inconsistency has a name: scareware. One of the most popular examples is called Mac Security Plus. Having silently infiltrated a system, this virus deploys malicious activity that manifests as fraudulent memory shortage reports, misleading virus detection alerts, and unreliable claims about increasing Mac productivity with a single click.
This foul play is all about tricking the user into purchasing the scam application’s license to supposedly unlock its repair and optimization features. In general, by displaying fake “Your computer is low on memory” notifications, the pseudo-system utility tries to add a layer of pressure to its repertoire. No matter what type of malware is causing this fake warning activity, you should remove it without a second thought.
