2. Restart the computer and wait a few moments until Bitdefender is loaded. Open
Bitdefender to see if the error persists. Restarting the computer usually solves
the problem.
3. Check if you have any other security solution installed as they may disrupt the
normal operation of Bitdefender. If this is the case, we recommend you to remove
all of the other security solutions and then reinstall Bitdefender.

21.7. Bitdefender removal failed
This article helps you troubleshoot errors that may occur when removing Bitdefender.
There are two possible situations:
● During removal, an error screen appears. The screen provides a button to run an
uninstall tool that will clean up the system.
● The removal hangs out and, possibly, your system freezes. Click Cancel to abort
the removal. If this does not work, restart the system.
If removal fails, some Bitdefender registry keys and files may remain in your system.
Such remainders may prevent a new installation of Bitdefender. They may also
affect system performance and stability.
In order to completely remove Bitdefender from your system, follow these steps:
1. Go to http://www.bitdefender.com/uninstall and download the uninstall tool on
your computer.
2. Run the uninstall tool using administrator privileges.
3. Restart your computer.
If this information was not helpful, you can contact Bitdefender for support as
described in section “Asking for help” (p. 111).
21.8. My system doesn't boot up after installing Bitdefender
If you just installed Bitdefender and cannot reboot your system in normal mode
anymore there may be various reasons for this issue.
Most probably this is caused by a previous Bitdefender installation which was not
removed properly or by another security solution still present on the system.
