If you are unable to uninstall the Total Defense Anti-Virus for MAC using this method, please follow the steps below:


IMPORTANT! If you have a backup disk, we recommend you to make a fresh backup before proceeding further. See more details in this article:


1. Restart your Mac and press Command-R during the restart until you see the Apple logo. In some cases you will be prompted to choose the language. Choose your desired language and click on the arrow at the bottom to continue.

3. Select your startup disk (in the example Macintosh HD):

• If it’s already mounted, you will see the Unmount option. In this case proceed with step 4.

• If it’s not mounted, click on Mount. If it’s locked by FileVault, you will be prompted for your administrator password to unlock it. Enter the same password you use at Mac login.

4. Quit Disk Utility to return to the Utilities window: click on Disk Utility in the menu bar (next to the Apple logo) and select Quit Disk Utility or simply close the window.


5. In the menu bar click on Utilities and select Terminal.

6. In the Terminal window type the following set of commands. At the end of each line, press Return/Enter on your keyboard.

NOTEPlease make sure you type the commands exactly as you see them in the steps below. Failure to do so may result in data loss.

So, we type (there is a space after the “ls” command):

LS /Volumes/

and press Return. This will display all the mounted volumes like in the picture below. If you see your startup disk (Macintosh HD) you may continue with step b). Otherwise, it is possible that you haven’t mounted the startup disk. In this case, quit the Terminal window, go back to Disk Utility and mount the disk. You may also run a First Aid to fix any potential disk errors.

8. Now let’s see if we have the SelfProtect.kext extension in the Extensions folder. We will use the same “LS”  command:

LS /Volumes/Macintosh\ HD/Library/Extensions/

9. We have the SelfProtect.kext. The next step is to delete it. To do that, type in:

rm –rf /Volumes/Macintosh\ HD/Library/Extensions/SelfProtect.kext

10. The SelfProtect extension was removed and we can move to the next step: remove the Total Defense folder. Type in:

rm –rf /Volumes/Macintosh\ HD/Library/Totaldefense/


11. Restart your computer and the Total Defense MAC AV program will no longer be installed on the device.
