Therefore, it is important to verify the source of an executable file before running it.

This is the purpose of this article, to check whether SystemMonitor.exe is a legitimate file that won’t compromise your safety and the health of your system if run.

Is SystemMonitor.exe a Virus?

Moreover, the idea also enables cybercriminals to deceive users into thinking they are getting legitimate software while installing a masked version that has different intentions. So, how do you identify if you are dealing with the SystemMonitor.exe virus version or a legitimate one?

When you want to identify if the process is legit or a virus, start by checking its location. Confirm that the file’s location is C:Program Files\(x86)Moo0SystemMonitor. To confirm the legitimacy of the file, you must launch Task Manager, and then click the columns field before adding Verified Signer. Check the value of the Verified Signer for the SystemMonitor.exe process. If it is indicated as Unable to verify, it means you are dealing with a malicious file.

Should SystemMonitor.exe Be Removed?

Many hints can indicate that the type of SystemMonitor.exe file needs to be removed or not. For instance, if the process is consuming high CPU power, then it must be removed immediately. You can stop the SystemMonitor.exe process by uninstalling the app associated with the file. If it is a malicious file posing as SystemMonitor.exe, you will need a trusted anti-malware security software to get rid of it.

You can also check if the SystemMonitor.exe process is causing high CPU usage by opening the Task Manager by pressing Ctrl + Shift + Escape keys simultaneously. Go to the process of interest and check under the CPU column. It should be less than 1%. You can also check if disk usage is high. If you suspect you are dealing with malicious crypto-mining software, in the Task Manager, check under the Network column.

If the SystemMonitor.exe process you are dealing with is rogue, you will have to follow the removal process below.

  1. If the spoofed SystemMonitor.exe file version came through a program, there must be an uninstaller file linked to it. Check for the uninstaller file located in a directory similar to C:Program Files>Moo0>Moo0 System Monitor >System Monitor> SystemMonitor.exe_uninstall.exe, and run it.
  2. If the SystemMonitor.exe gets installed via the Windows Installer, you should press Windows + I keys to launch system Settings, and then select Apps. Identify the program you wish to remove, click on it, and then select the Uninstall button.

How Does SystemMonitor.exe Virus Spread?

In most cases, developers that spoof malicious programs to appear legitimate use various methods to spread malware. The most common methods include:

  • Software bundling technique – This method allows cybercriminals to attach malware installers on freeware downloads. The additional installers are then set to trigger when the user selects the Recommended or Express installation process. To avoid such, you must always select the Advanced or Custom installation process to gain control over what gets installed. You should also download executable files from official sites or trusted distributors.
  • Adware – This channel lets developers advertise their malicious content online using fake headlines, images, fake software updates, or misleading promotions. Once the unsuspecting user clicks on the ad, malware download can be triggered.
  • Browser hijackers – These programs take over the user’s default browser, manipulate it in such a way that results shown are sponsored regardless of the input. The program will perform redirects to the site with malware content making the system vulnerable to attacks.


Since SystemMonitor.exe is a legitimate process, its removal process must be handled with care as it may lead to the malfunction of certain programs. A thorough investigation has to be carried out before removing the process. You must learn more about executable files and how to identify fake ones here.
