Why does the RAVBg64.exe use so much CPU?

The RAVBg64 file is an executable program designed to hide malicious activities such as keylogging, screen recording, webcam spying, etc. This article explains how to detect and remove the RAVBg program.

Fix 1: Turn Realtek Audio Programs on and off

This may just be sufficient in solving the issue. If it doesn’t work, follow the next step.

You’ll have to disable the actual realtek audio device in the Device Manager. Then, select “Disable”. After disabling it, restart your computer.

Now, open up the Device Manager again and enable the realtek audio device once more. Restart your PC once more.

If the above method still fails, try the following.

Find the Realtek HD Audio Driver and uninstall it. Now, reboot your computer.

When you try to install a newer version of Windows 10, it might show a warning message saying that the installation files are damaged. In such cases, you must delete the files before trying to install a new one.

To do this, press Win+R keys together. Type %AppData% into the Run dialog box and hit Enter key. A folder named Roaming will appear. Open it. Delete the contents of the folder.

Fix 2: Remove the Realtek Audio Drivers and update them.

To fix the sound issues, you must uninstall the old drivers and replace them with the new ones. You can do this manually or use Auslogics Driver Upgraders. If you want to go the automatic route, download Auslogics Driver Upgraver. Run the program and let it scan your PC for outdated and corrupt audio drivers. When it finishes scanning, it will tell you what drivers are causing problems and how many times each one is used. Click Fix All Problems and let the tool take care of the rest.

If you don’t see the “Fix All Problems” button, simply select “Scan Now”. Once the process is finished, you’ll receive a list of updated drivers. Install them and restart your system.

You can now enjoy better quality audio without having to deal with annoying popups every time you play a song.

Fix 3: Make a change to the registry

Click “Check now”. You’ll likely see some updates listed here. Select the update titled KB3035583. This is a security patch for Microsoft Edge. Install it.

Now, open the Run dialog box (Win + R). Type regedit into the text field and press Enter. A window will pop up showing the contents of the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Edge folder. Right-click on the SRSLabs entry and select Delete. Now, close the registry editor and reboot your PC.

If you still experience problems, follow the instructions below.

1. Open the Run dialog box again (Win + R).

2. Type regedit.exe into the text field and hit Enter.

3. In the left pane, navigate to HKEY_CURRENT_USER\Software\Classes\. There should be no entries there.

4. Name the value APO and set the data type to REG_DWORD. Set the value to 0x00000001.

How to add new values to the registry

The registry is a database used by Windows operating systems to store information about installed programs, hardware devices, drivers, and settings. You can use the registry to make changes to how your computer works. For example, you might want to add a new value to tell Windows what type of video card you have installed. Or you might want to set up your computer to automatically start certain programs whenever you turn on your PC.

This opens the Registry Editor window. If you are comfortable editing the registry yourself, you can do so without having to open the Registry Editor. Instead, you can simply follow the steps below.

Step #1 – Open the Registry Editor

To open the Registry Editor, press Win+R keys together and enter Regedit.exe into the box that appears. A small dialog box will pop up asking whether you really want to run the program. Click Yes.

Step #2 – Find the key you want to edit

In the left pane of the Registry Editor window, expand HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. From there, navigate down to the following subkey: Shell. Double-click Shell.

Step #3 – Create a new string value

Name it SRS Labs > right-click SRS Labs > New >> Key > name it APO.
