I CANT UNINSTALL BITDEFENDER

Help please i cant uninstall bitdefender, nor launch it.

When i try to launch bitdefender it says it needs a restart to do a setup but after i restart it does the same thing.

then when i try uninstalling the agent it says i need to uninstall the bitdefender total security application and then, when I try uninstalling the bitdefender total security application it acts as if i wanted to install it again.
