Reason Security Engine

The Reason Security Engine is an outdated component often linked with RAV Antivirus, an obsolete security software categorized as a potentially unwanted program (PUP). Users have reported the Reason Security Engine causing significant system slowdown, consuming an excessive amount of RAM, and monopolizing disk usage, often reaching 100%. Despite attempts to close it via the task manager, the engine remains operational, frequently denying access due to its background operation. Uninstallation poses a challenge as it may not be visible in the control panel. Furthermore, even after removing the associated RAV Antivirus, the Reason Security Engine persists, suggesting it embeds itself deeply within the system. Given these issues and its antiquated nature, it’s advisable to replace it with up-to-date security software.

How to uninstall ReasonLabs?

To uninstall ReasonLabs, you’ll first need to run its uninstaller, but since this may not be enough to get rid of everything, then you’ll need to either use a professional removal tool or follow our guide to manually find and eliminate any residual traces of the malware.

What is the ReasonLabs application virus?

The ReasonLabs application virus is actually a legitimate app that is mistakenly referred to as a virus due to it sometimes getting installed without the user’s informed permission. Though it’s technically a safe software, it’s still recommended to delete the ReasonLabs application if it got installed on your PC without you wanting it there.

How to delete ReasonLabs?

To fully delete ReasonLabs after running its uninstaller, we recommend checking system settings such as the Registry or the Services and Startup items and remove from there anything that may be related to the app. A detailed guide on how to do all that is provided for you on this page.

How to turn off Reason Cybersecurity?

To turn off Reason Cybersecurity, you will need to uninstall the application from your PC either by following the steps detailed in our removal guide, or by using a specialized removal tool that can automatically get rid of the undesired application and all of its residual files and settings.

Reason Security

Reason Security is a security software that may install itself without explicit user consent, often alongside outdated or unwanted software like RAV Antivirus. Once embedded in a system, it poses various challenges for users. It may not appear in Control Panel listings or settings apps, complicating its removal. Furthermore, it runs a component known as the Reason Security Engine in the background, which can consume significant system resources. Users report an inability to disable Reason Security through standard system settings, even after seemingly successful uninstallations, indicating it may leave residual traces. If the software is causing issues, it’s recommended to utilize specialized removal tools, like the one from this page, or to follow the detailed removal guide we’ve included below.

RAV Antivirus is potentially unwanted software that gets installed along with Reason Security

The Reason Security Engine service

The Reason Security Engine service is a process linked to the outdated RAV Antivirus program, which is often flagged as potentially unwanted. Although the service itself isn’t harmful, it’s associated with a program that offers inadequate security features and poses potential system vulnerabilities due to it being outdated. These vulnerabilities may be exploited by genuine malware, thereby jeopardizing your cybersecurity. Despite its non-malicious nature, the Reason Security Engine service may lead to intrusive behaviors like fake alerts, causing undue stress and confusion. Moreover, its high resource usage can affect system performance. Given these factors, it’s advisable to eliminate it along with the RAV Antivirus, ensuring a thorough system cleanup to minimize potential risks.

Reason Security Engine high CPU usage

The Reason Security Engine high CPU usage is a common problem faced by most users who have this engine on their machines. This service is linked with the outdated RAV Antivirus and can lead to system slowdowns and potential instability. This excessive utilization of system resources can disrupt other vital processes, hampering overall performance and potentially leading to system crashes. Additionally, the Reason Security Engine may trigger unwarranted alerts, creating a confusing user experience. Since RAV Antivirus itself is considered a potentially unwanted program with subpar security measures, it might leave your system vulnerable to actual malware threats. Therefore, despite the Reason Security Engine itself not being malicious, its Reason Security Engine high CPU usage and its other adverse impacts on system make its removal strongly recommended.

ReasonLabs application

The ReasonLabs Application is a safe security tool designed by the legitimate software company ReasonLabs. However, issues arise when the software gets bundled with other downloads, potentially installing without explicit user consent. The bundling practice often results in the automatic installation of the Reason Security Engine, an outdated component associated with various system issues. Despite being non-malicious, this engine can cause substantial CPU usage, leading to system slowdowns, unwarranted alerts, and possible instability. Thus, while the ReasonLabs Application is designed to enhance your system’s security, its unintended installation and the subsequent automatic inclusion of the Reason Security Engine can lead to performance degradation and potential exposure to security risks, necessitating its careful management or removal.

Reason Cybersecurity

In conclusion, Reason Cybersecurity, developed by the reputable company ReasonLabs, provides protective software solutions intended to bolster system security. However, some associated elements, such as the Reason Security Engine, can inadvertently disrupt system performance, particularly when bundled with other software and installed without user knowledge. Issues may include excessive CPU usage, misleading alerts, and even potential system instability. The fact that this component is sometimes installed without explicit user consent has led to a degree of skepticism and concerns regarding user privacy and system integrity. While the core software from ReasonLabs is undeniably safe, it’s essential for users to understand the full implications of bundled installations to ensure optimal computer performance and safety.

How to Uninstall Reason Security Engine

To get rid of Reason Security Engine:

  1. Uninstall RAV Antivirus and any other potentially unwanted programs from Apps & features settings section.
  2. Quit the Reason Security Engine process and delete its location folder.
  3. Clean the Startup items list, the Task Scheduler, the Services list, and the System Registry.
  4. Get rid of any remaining Reason Security Engine or RAV Antivirus files.

Completing those four steps should usually result in the full deletion of anything related to the Reason Security Engine process or the RAV Antivirus PUP. To make sure that you correctly complete each of the steps, make sure to check out the detailed instructions we’ve shown below.

Detailed Reason Security Engine removal guide

Step 1

Open the Start Menu/click in the Start Menu search bar and type Apps & Features. Next, scroll down to see the list of apps and programs that are installed on your PC and look for anything named RAV Antivirus or Reason Security Engine. If you notice an app or apps with those names, select them, select Uninstall, and proceed to uninstall the potentially unwanted program/s by following the prompts. If the uninstaller asks you if you’d prefer to keep on your computer something related to the unwanted program, make sure to refuse that offer. Also, some unwanted apps try to trick you into installing other undesirable software when you are running their uninstallers – be sure to carefully read all the options in the uninstaller so that you don’t end up getting some other PUP on your PC.

Step 2

Open the Task Manager with the Ctrl + Shift + Esc keyboard combination, then visit the Processes tab and there look for the Reason Security Engine process. When you find it, right-click it, click Open File Location, then return to the Task Manager (without closing the file location folder), right-click the process again, click Quit Process, and click Quit again to confirm. Now go back to the file location folder, delete everything that’s in it, and then delete the folder itself. If there are any items that can’t be deleted right now, leave them as they are for now, and, once you finish the rest of the guide, try to delete them again.

You should also look for any processes named RAV Antivirus or anything similar and do the same thing with them and their file location folders. Additionally, if you notice any other sketchy and suspicious processes in the Task Manager, go to their file location folders, scan the contents of those folders with the next free online malware scanner, and if anything is flagged as potentially unsafe, quit the related process and delete the entire file location folder.

    Step 3

    We recommend putting your PC in Safe Mode for the next steps, so this is what you should do now. Here are our instructions on How to enter Safe Mode on a Windows PC if you need help with this.

    Step 4

    Now, it is time to visit different sections and settings in your system where there may be remnants of the RAV Antivirus/Reason Security Engine. Go to each system section by typing the items/names shown below in the Start menu search and then hit Enter to open the first search results. After that, complete the instructions we’ve provided for each item:

    Services – When the Services window opens, look through the services listed in it, searching for anything named RAV Antivirus or Reason Security Engine. If you find an item or items that have such names, right-click them, click Properties, and then set the Startup type to Disabled. Do this with every services item that you think is linked to the Reason Security Engine process and/or the RAV Antivirus PUP.

    3 1024x526

    Task Scheduler – In the Task Scheduler, first click the Task Scheduler Library folder shown in the top-left, and then look at the tasks shown in the list. Again, search for items named Reason Security Engine or RAV Antivirus. If such items are found, right-click them, select Delete, and confirm the action.

    5 1024x472

    Msconfig – Select the Startup tab in the System Configuration window, and then, if you see a button named Open Task Manager, click it. When you get a list of the system’s startup items, look carefully through them and if you see entries named Reason Security Engine or RAV Antivirus, disable them.

    6 1024x652

    Regedit.exe – Allow the app to make changes to your system by clicking Yes when your permission is required and then, when the Registry Editor shows up, press Ctrl + F. In the search bar that pops up, type RAV Antivirus, perform the search, delete the first item that gets found, and search again. In this way, make sure that all items that come up for this search are deleted. Then do the same with search phrases “RAV”, “Reason Security”, and “Reason Security Engine”.


    After you’ve made sure that everything related to those four search phrases is deleted, manually go to the following three Registry locations by expanding the folders to the left. In each of those locations, look for items with unusual names that seem to be randomly generated (for instance, items with names like this: “903urj09fd0923ut09ik3e90turr”). Tell us in the comments if you notice anything like this, and we will tell you what to do with it.

    • HKEY_CURRENT_USER/Software/Random Directory. 
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main

    Step 5

    Lastly, there are a couple of folders where there may be file remnants from the RAV Antivirus PUP, so you should check for such remnants and delete what you may find. Before that, however, type Folder Options in the Start Menu, open the first result, click the View tab, and there check the Show hidden files, folders, and drives option. After that, click OK so that the changes are saved. Now, type each of the following (together with the “%” symbols) in the Start Menu search and open the respective folders. In all of those folders, except %Temp%, delete only the most recently created files (anything created since the time you think RAV Antivirus got installed on your PC). In the Temp folder, you must delete everything – since there will likely be thousands of items there, the easiest way to delete them all at once is to press Ctrl + A while in the folder, then press Del, and confirm the deletion.

    • %ProgramData%
    • %WinDir%
    • %AppData%
    • %Temp%
