13 Fixes For Your Computer Is Low On Memory Warning

What does “Your computer is low on memory” mean on a Mac?

“You have Low Memory” Mac virus is a potentially unwanted application (PUA), a part of the adware/scareware category that displays misleading warning messages. Programs like this display pop-ups, alerts, and other forms of promotional content to force the user to purchase such products or services. 

Users are lured into giving permission to the application that displays the pop-up to control their browsers and the data they store on them.

PUAs that display the said message have been spotted by cyber security experts, including, but not limited to:

  • BeAware
  • ScreenCapture.app
  • ScreenSaver.app
  • Spaces.app
  • MacSecurityPlus

As the pop-up page states, the computer has a low amount of RAM, and it is recommended that the user closes some opened applications to free memory. 

Due to the pop-up hiding another window, the “Close” button from the first window also contributes to the consent option for the next pop-up. The result is that users click “Close” and the hidden button is clicked unintentionally as well. 

A disguised pop-up is a system window through which a rogue application requests potentially harmful capabilities or actions. For example, the app might request permission to control the browser (e.g., Google Chrome, Safari, etc.) in this deceptive manner. The app behind this pop-up can then attempt to access files and data stored in the browser, and exploit it in various ways once the permission is granted.

Additionally, users who attempt to uninstall the application displaying the message receive the message “Your computer is low on memory”. To avoid this pop-up, please remove the selected app right away if it appears.
