How to remove 'Your computer is low on memory' from Mac computers

What is 'Your computer is low on memory'?

'Your computer is low on memory' is a deceptive pop-up window displayed by rogue applications (e.g. adware, browser hijackers or other Potentially Unwanted Applications - PUAs). It is displayed by ScreenSaver.app, ScreenCapture.app, Spaces.app, MacSecurityPlus and other dubious apps. The pop-up is designed to trick users into giving the application displaying it various permissions such as control over browsers and the data stored therein.

The text presented in the pop-up claims that the computer is low on memory and suggests that the user close some opened applications to free up memory. This pop-up hides another window, and thus the 'Close' button of the first window is also the consent option of the next pop-up. Therefore, when 'Close' is clicked, users unintentionally click the hidden button as well. The disguised pop-up is a system window through which the rogue application displays requests to allow potentially harmful capabilities/actions. For example, in this deceptive manner, the app might request permission to control the browser (e.g. Google Chrome, Safari, etc.). Once such access is allowed, the app behind this pop-up can gain access to documents and data stored on the browser, and then misuse it in various ways. Furthermore, 'Your computer is low on memory' is displayed when users attempt to uninstall the application displaying it. Therefore, if you encounter this pop-up, you are strongly advised to immediately remove the app responsible for it.

PUAs such as ScreenSaver.app, ScreenCapture.app, Spaces.app, and MacSecurityPlus display 'Your computer is low on memory'. These unwanted applications have various dangerous capabilities. Adware-types display intrusive ads (e.g. pop-ups, banners, surveys, coupons, etc.), which significantly diminish the browsing experience by limiting browsing speed and website visibility. Additionally, when these ads are clicked, they redirect to sale-based, untrusted, compromised, deceptive/scam and malicious sites. They can also be triggered (by clicking them) to download/install content (e.g. PUAs) without users' consent. Other unwanted apps called browser hijacker modify browsers, restrict or deny access to settings and promote fake search engines. Most PUAs (regardless of other capabilities) can track data. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather users' personal information derived from it (IP addresses, geolocations and other details). This collected data is shared with third parties (potentially, cyber criminals) seeking to generate revenue by misusing it. To summarize, rogue apps can cause browser and system infiltration/infections, lead to serious privacy issues, financial loss and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

An example of a pop-up displayed due to rogue apps is '* will damage your computer. You should move it to the Trash.', which is caused by Helperamc, Hlpradc, Smbstrhlpr, Helpermcp and others. While unwanted applications do not need express user permission to infiltrate devices, they can also be promoted by various deceptive/scam web pages. They are promoted as legitimate and useful software with a broad array of features, but despite how good these offers may sound, they are typically nonoperational. PUAs can cause serious problems. These apps are simply used to generate profit for the developers. PUAs run intrusive advertisement campaigns, force-open all kinds of untrusted and malicious websites, hijack browsers and collect private data.

How did potentially unwanted applications install on my computer?

PUAs proliferate via the download/install set-ups of other software. The deceptive marketing method of pre-packing normal products with unwanted or malicious additions is called 'bundling'. Rushing download/installation processes (e.g. skipping steps and sections, using pre-set options) endangers devices with potential infiltration and infections. Some PUAs have 'official' download pages. When clicked, intrusive ads can stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

All products should be researched before download/installation and/or purchase. Use only official and verified download channels. Download sources such as free file-hosting sites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders are untrusted and should be avoided. When downloading/installing, you are advised to read the terms, explore available options, use the 'Custom/Advanced' options and opt-out of all additions (apps, tools, features and so on). Intrusive ads usually seem legitimate and harmless, however, they can redirect to dubious web pages (e.g. gambling, pornography, adult-dating and others). If you encounter these advertisements/redirects, check the system and remove all suspect applications and/or browser extensions/plug-ins without delay. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

Text presented in the pop-up window:

IMPORTANT NOTE! Most rogue applications are hidden deep within the system and do not appear on any list of installed software. Therefore, the removal process might be complicated. Taking the aforementioned ScreenCapture.app as an example:

1) Navigate to the '~/Library/Application Support/.screencapture/' directory, right-click on the 'ScreenCapture' application, and select 'Show Package Contents':

2) Navigate to the 'Contents/MacOS' directory and delete the 'ScreenCapture' application:

3) Once the previous steps are performed, the process associated with the ScreenCapture application will no longer be automatically re-started and you will be able to easily terminate it and remove the remaining application files:

4) After removing the ScreenCapture application, navigate to the '/Users/Test/Library/Application Support' directory and enable the display of hidden directories. Then, search for a directory with a dubious name (e.g., '.helper', '.dir', or similar), which contains an application called 'Finder'. Once located, this entire directory must be deleted. Note that MacOS actually has a genuine Finder application. Yet, the malicious version has a completely different icon (typically, a Terminal logo) and criminals simply use this as a disguise:
