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:
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.

2. Disable Startup Programs
It is possible that the computer is low on memory if there are many startup programs. Rather than enabling these programs, it is advisable to disable them here.
- Open the Task Manager.
- Go to the Startup tab.
- Under the Startup tab, right-click on a program to choose Disable.
If it fails to fix the low memory error in Windows just go to the next way.
3. Manually increase Virtual Memory
You can also increase virtual memory to resolve the low memory issue. Due to the lack of apps for this specific purpose, you’ll have to do it manually.
- Enter advanced system settings in the search of Windows and click on the first result. You can also press the Windows key + R key on your keyboard to add the Run dialog box, enter sysdm.cpl and hit OK to open the System Properties window.
- Under the Performance section, select the Advanced tab and click Settings.
- In the new window, click the Advanced tab again and click Change from the Virtual Memory panel.
- Uncheck “Automatically manage paging file size for all drives”.
- Click on one drive and then select Custom size. There is also a need to change the initial size (MB) and the maximum size (MB) in these two sections.
- You should set sizes that are larger than the recommended size.
- Finally, click OK to save the changes.
4. Upgrade RAM
You can upgrade your RAM if you don’t have a lot of RAM and have a computer with low memory problems often. A RAM upgrade can help your Windows computer run faster and cause fewer system freezes or hangs.
It is generally recommended that the majority of you have at least 8GB of RAM. It’s a bit of a sweet spot. Gamers or those who need to run a lot of larger programs should have 12-16 GB.
Before installing new RAM, it’s a good idea to gauge how much RAM your computer can carry. It depends on the version of Windows and the motherboard. Furthermore, you must find out what type of RAM your computer can use.
All these things are important to consider, otherwise, your new memory won’t work with your computer. Once this is done, you can open the computer case and install the new memory.
Note: If you’re not a technical person, you may want to leave this to the professionals. A computer expert can assist you.
5. Update Windows to the Latest Version
Ensure that your Windows OS is up to date. In case you forgot, Microsoft constantly releases Windows updates to improve the system’s stability and fix various problems.

Go to “Settings”. To see if a new version of Windows has been released, click “Update & security” and click the “Check for updates” button under the Update status.
Install the update and restart your computer afterward, if there is one.
6. Check and Repair Disk Errors
Command Prompt allows you to perform a disk check.
- Start Command Prompt as administrator and type the command chkdsk C: /f followed by Enter. Your partition letter should replace C.
chkdsk displays a warning that it needs to fix the file, but it does not fix any errors if you do not specify the /f parameter.
chkdsk C: /f detects and repairs logical problems affecting your drive. Run the chkdsk C: /r parameter as well to repair physical issues.
7. Run System CleanUp to Remove Junk and Temporary Files
By deleting junk and temporary files and folders, you can also fix the “Your computer is low on memory” issue. Using a free PC disk cleaning tool will help you make it work seamlessly.
In addition to scanning your computer for inactive files that hog disk space, the software allows you to remove useless large files, system junk files, and invalid entries on your Windows OS. The system cleaning process will then be initiated.
8. Remove recently installed software
Try uninstalling any recently installed new software to fix the problem if you weren’t experiencing the problem before.
- Click on Start, then type Control Panel. Click Uninstall on the recently added program(s).

You may also receive the Your computer is low on memory popup when your system files, such as registry files, are corrupted. Using the built-in System File Checker in Microsoft’s operating system is a good method to check for system file corruption. The utility will scan and verify the integrity of all protected system files and repairs those that have problems.
- In the Search box, type cmd.
- Right-click Command Prompt and choose Run as Administrator.
- Now type the sfc /scannow command, and press Enter.
- Wait for the scanning process to complete and then restart your computer.
If corrupted system files cause the computer to have low memory, the problem will be solved.
11. Run a full system scan
You might receive the Your Computer is low on memory alert when malicious files are installed. In this case, you only need a strong antivirus program and an antimalware tool.
Perform a full scan of your system to make sure that your computer is free from malware. You can use built-in antivirus in Windows or a third-party antimalware program to scan.
12. Correct system errors
Usually, system errors are caused by hidden, unnecessary program leftovers, junk files left over after program uninstallation, old registry keys, etc. These can sometimes cause the “Your computer is low on memory” error message to appear.
You can either eliminate these manually or with the help of third-party software to free disk space and reduce memory usage.
13. Disable Windows Memory Warnings
For systems with RAM less than 4GB, this method is not recommended as a solution to the “Your computer is low on memory” error message.
In order to do this, we need to stop DLL files radardt.dll and radarrs.dll from being loaded by Diagnostics.
By pressing Windows Key + R, type “Regedit” and hit enter, the Registry Editor will open.
Navigate to and open HKEY_LOCAL_MACHINE
Click on the System folder.
Under System, click Current Control Set.
WDI is located under the Control folder, so click on that.
After that, you should find and delete the following registry keys in the DiagnosticModules folder.
