Cannot kill Bitdefender process after uninstalling it, no launch daemons found Recently, I installed Bitdefender Antivirus. I wanted to remove it after the trial period. After uninstalling it via CCleaner, moving all stuff from Librar, I found there is still an agent up and running and I cannot disable. I cannot kill that process even as root:

bdagent - pid 65

sudo su - 
kill -9 65
-sh: kill: (65) - Operation not permitted


Killing it via Activity Monitor doesn't work either.

Output of ps is:

root# ps -ef | grep defender
    0    65     1   0 11:08PM ??         6:49.98 /Library/Bitdefender/Central/Agent/bdagentd

The Bitdefender folder is:

drwxr-xr-x    4 root  wheel   128 Jul  2 19:32 Bitdefender


I cannot remove it, even as root, I cannot chown, nothing.

Is there any way to just remove this?
It is blocked by one or more of the extensions it installs: FileProtect.kext, SelfProtect.kext, TMProtection.kext

You should always use Bitdefender's uninstaller at /Applications/Bitdefender/BitdefenderUninstaller and not these other apps you mentioned. Follow the instructions at https://www.bitdefender.com/consumer/support/answer/1784/

If that doesn't work, that page links to another page that covers the manual removal process. https://www.bitdefender.com/consumer/support/answer/1446/
