Rsenginesvc is a potentially unwanted Windows encountered on PCs that have the RAV Antivirus installed on them. Rsenginesvc is not a direct threat to the security of your system and data, but it still needs to be removed in order to keep the computer safe.


If you’ve noticed increased memory and/or CPU consumption in your computer and when you checked the Task Manager, it turned out that the process responsible for this is rsenginesvc, then you should probably check your system for the presence of a PUP (potentially unwanted program) named RAV Antivirus, as the latter is this software is commonly associated with the unwanted process.

Note that manually quitting the rsenginesvc process in the Task Manager is likely not going to have the needed effect. While the process may be stopped for a moment, more likely than not, it will be re-launched either a coupled of moments later or, at the latest, once you restart your computer. Therefore, if you want to fully and permanently get rid of rsenginesvc, you will first need to make sure that anything related to RAV Antivirus that’s currently in your system gets deleted.

Is rsenginesvc a virus?

Rsenginesvc is not a virus and even though it may cause slow-downs and performance issues in the system, it’s typically not a harmful process. However, to keep your PC protected from real viruses, rsenginesvc should be removed alongside any associated software (such as RAV Antivirus).

Rsenginesvc is basically a process that is launched by the RAV Antivirus PUP. RAV Antivirus is technically a security software and there aren’t any reports of it being malicious. However, it’s also not something that’s good for your system. At best, this is an old, outdated, poorly optimized, and pretty much useless tool that does nothing that’s beneficial to you and instead needlessly uses up your system’s resources and bothers you with its presence.

However, even if you aren’t particularly annoyed by the presence of RAV Antivirus and its effects on your system’s performance and resource distribution, you should still make sure to delete this app and, thus, permanently kill the rsenginesvc. The reason for this is that the presence of RAV Antivirus on your computer could potentially make your system vulnerable. As we said, this is very outdated software that is likely to have exploitable bugs which could be used by real malware to infiltrate your system. Not only that, but it’s also possible that RAV Antivirus may get hijacked by scammers and used as scamming tool that would show you fake ads, misleading download and update prompts, and links to phishing pages. All in all, though RAV Antivirus is technically a legitimate security program, nothing good can come from its presence on your computer, which is why it is recommended to remove it.

Another point we should make here is that, if you do not remember installing the program behind the rsenginesvc process on your PC and have no idea how it got there, it is likely that the unwanted software was installed on your computer with the help of a file-bundle. This means that it’s possible that other undesirable apps may have also entered your system unbeknownst to you. Some such apps may even be considered malware. This is yet another reason why removing RAV Antivirus and permanently quitting the rsenginesvc process is strongly recommended. For this reason, below you will find a detailed guide that will show you a list of manual steps that you can complete in order to clean your computer from RAV Antivirus, rsenginesvc, and any other unwanted process or app that may be in the system at this moment.

If the rsenginesvc process is currently in your Task Manager, we advise you to go directly to the guide and start completing its steps. The entire process should take no more than 20 minutes and by the time you are finished, your system should be clean and secure.



How to get rid of rsenginesvc

Here is how to get rid of rsenginesvc:

  1. Uninstall the RAV Antivirus app from the Apps & Features section in your PC’s settings.
  2. Quit rsenginesvc and other unwanted processes, and delete any files and folders associated with them.
  3. Clean the System Registry, the Startup items list, the Task Scheduler, and disable any rogue/unwanted services.
  4. Delete any remaining files associated with RAV Antivirus or rsenginesvc.

If you correctly perform each of these four steps, the RAV Antivirus PUP should be removed and the rsenginesvc process should be permanently stopped. To learn the exact way each step is supposed to be performed, be sure to check out the detailed instructions we’ve included below.

Full rsenginesvc removal guide

Step 1: Uninstalling RAV Antivirus

First, you need to click in the search bar next to the Start Menu or simply open the start menu, type Apps & Features, and click on the first result. Scroll down a bit to see a list of the programs installed on your PC. Try to find RAV Antivirus in that list, click on the program’s entry, and then click Uninstall. Complete whatever steps and follow whatever prompts show up on your screen to uninstall the program, but remember to carefully read everything so that you don’t accidentally allow anything related to that program to be allowed to remain on your computer.

After the uninstallation, search the list for any items named rsenginesvc or for other questionable and potentially unwanted programs and uninstall them too.

Step 2: Quitting the rsenginesvc process

Press CTRL + SHIFT + ESC to evoke the Task Manager, open Processes, and search for the rsenginesvc process. When you find it right-click it, and click Open file location.

Without closing the location folder, switch back to the Task Manager, select the rsenginesvc process, click End Task and confirm the action.

2 1 1024x666

Now go to the location folder that you opened and delete everything that’s in it. After that, try to delete the folder itself. If you are unable to delete the folder and/or any of the items contained in it, continue with the guide. After you’ve performed all other steps, try to delete the location folder of rsenginesvc once again.

Next, check the Task Manager for other sketchy processes that may be related to rsenginesvc or RAV Antivirus and do the same thing with them (quit them and delete their file location folders). If you are not sure if a given process is linked to the unwanted software, use the malware scanner included below to test the files in the file location folder of that process.

    Step 3: Safe Mode

    It is strongly recommended to continue with the next steps while in Safe Mode – this will help prevent rsenginesvc or any other undesirable processes from starting again. Here is our guide on How to boot into Safe Mode on a Windows PC.

    Step 4: Cleaning the system settings

    For this step, you must find and delete/disable any system settings linked to the RAV Antivirus PUP and the unwanted rsenginesvc process. To do that, type the names of the following system settings sections as they are shown below, go to those settings, and perform the instructions we’ve provided for them:

    Regedit – First, confirm that you want to open the Registry Editor app, and then, when it opens, press Ctrl + F to evoke its search box. In the search box, type RAV Antivirus, press Enter, and delete whatever item (if any) gets found. Perform the search again to see if there are other related items and in this way delete everything related to rsenginesvc. Once you’ve done that, perform a search for rsenginesvc and delete all items that come up as search results. Also do the same with these search phrases: “Reason Security Engine”, “RAV”, and “Reason Security”.

    Once you’ve deleted all items that may be related to rsenginesvc, manually go to these three Registry Editor locations using the left panel and check them for any items with odd-looking names that seem to comprise random letters and numbers (for example – “903ud09t0933909tg0fj09r30”). Should you notice anything like this, let us know down below in the comments, and we will inform you what to do next.

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

    Services (you can also try with “services.msc”) In the Services window, look at the list of services and try to find anything named RAV Antivirus, RAV, Reason Security Engine, rsenginesvc, or anything similar. If you come across one or more such services, right-click them, go to Properties, set the Startup type to Disabled, and click OK. Do this for every service that may be related to RAV Antivirus or rsenginesvc.

    Task Scheduler – Click the Task Scheduler folder in the top-left corner of the window and then loo through the list of scheduled tasks, searching for anything named RAV Antivirus, Reason Security Engine, rsenginesvc, or anything similar. If you find any task or tasks with such names, select them, press Delete, and confirm the deletion.

    System Configuration – Go to the Startup tab. If you are on Windows 7, there you will see a list of startup items. If you are on a later Windows OS, you must first click Open Task Manager to see the list. In the Startup items list, look for RAV Antivirus, rsenginesvc, or Reason Security Engine entries and if you find any, disable them.

    Step 5: Deleting leftover files

    Completing steps 1-4 should be enough to rid you of the RAV Antivirus PUP and the rsenginesvc process, but since there may still be some remaining files related to them in several folders in your system, we recommend going there and cleaning those folders. First, however, type Folder Settings in the Start Menu, open the first item, go to View, and enable the Show hidden files, folders, and drives setting. Then press OK to save and apply the changes – this is done so that any hidden files related to the unwanted process become visible so that you’d be able to delete them.

    Next, again using the Start Menu search, type the names of folders we’ve shown below (together with the “%” characters) and open them one by one. In each folder, you open, sort the files and subfolders in it by data, and then delete the most recent items – the ones created since the date RAV Antivirus was installed on your PC.

    When you get to the %Temp% folder, press CTRL + A to select all of its contents and then press Del to delete them all – everything in that folder should be deleted.

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