rsEngineSvc.exe is a process related to an RAV Antivirus (Reason Core Security Engine Service), a potentially unwanted program. To protect your PC, it is important to uninstall rsEngineSvc.


rsEngineSvc is a process of a service related to RAV antivirus. The latter is an unwanted program (a.k.a rogue antivirus) that often comes within software bundles. rsEngineSvc.exe is a pillar process of that unwanted program, as it provides essential functionality.

If you observe high memory and/or CPU that comes from rsEngineSvc, it is advisable to investigate the presence of a potentially unwanted program (PUP) called RAV Antivirus. This software is the sole reason for this unwanted process to appear. Simply terminating the rsEngineSvc process in the Task Manager is unlikely to make a serious difference. Although the process may temporarily cease, it will likely be relaunched soon or after the computer is restarted. To completely and permanently eliminate rsEngineSvc.exe, it is necessary to remove any components associated with RAV Antivirus from your system.

Is rsEngineSvc.exe a virus?

Correct, rsEngineSvc.exe is not a virus. While it can contribute to system slowdowns and performance issues, it is generally not a malicious process. However, to ensure protection against actual viruses, removing rsEngineSvc and any associated software, such as RAV Antivirus is recommended. rsEngineSvc.exe is essentially a process launched by the RAV Antivirus PUP.

rsEngineSvc.exe – Really high CPU and GPU use

Even if you are not particularly bothered by the presence of RAV Antivirus and its impact on system performance and resource allocation, it is still important to delete the application and permanently eliminate rsEngineSvc. The reason is that the presence of RAV Antivirus on your computer could potentially make it vulnerable. This outdated software is likely to have exploitable bugs that real malware could use to infiltrate your system. Moreover, RAV Antivirus could be hijacked by scammers and used as a tool for displaying fake ads, misleading download and update prompts, and links to phishing pages. In summary, although RAV Antivirus is technically a legitimate security program, its presence on your computer does not bring any benefits, which is why removal is recommended.

How did I get RAV Antivirus?

It is worth noting that if you do not remember installing the program responsible for the rsEngineSvc process on your PC and have no idea how it got there, it is likely that the unwanted software was installed through a file bundle. This means that other undesirable apps may have entered your system without your knowledge, some of which may even be considered malware. This further emphasizes the importance of removing RAV Antivirus and permanently terminating the rsEngineSvc.exe process. For this reason, a detailed guide is provided below, offering manual steps to clean your computer from RAV Antivirus, rsEngineSvc.exe, and any other unwanted processes or apps that may be present.

If the rsEngineSvc.exe process is currently running in your Task Manager, we strongly advise you to proceed directly to the guide and start following its steps. The entire process should take no more than 20 minutes, and once completed, your system will be clean and secure.

How to remove it?

Removing such an app needs making use of a specific program. Proper antivirus should have high capability at scanning and be lightweight – to make no problems with usage also on weak computers. Additionally, it is recommended to have proactive protection in your security solution – to stop the virus even before it launches. Microsoft Defender lacks these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb choice that fits each of the discussed features.1

Before the malware removal, it is important to reboot your Windows into Safe Mode with Networking. Since rsEngineSvc.exe takes a lot of CPU power, it is needed to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

Booting the PC into Safe Mode with Networking

Press the Start button, choose Power and click Reboot while holding the Shift key on the keyboard.

Boot into Windows Safe Mode

Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

When your computer is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not launched with the system start. That allows you to clean the computer.
