I Cannot Remove Bitdefender From My Personal Laptop

I discovered approximately two days ago that Bitdefender had somehow been installed on my personal laptop running Windows 11 without my knowledge or consent. Since then, my computer has become almost unusable.
I am unable to open many of my programs, and nearly every action now requires administrator privileges. The system repeatedly asks for an administrator password that I do not have, making it feel as though control of my own computer has been taken away from me. This is my personal device, and I never knowingly installed Bitdefender or authorized anyone else to install it.
I have no idea how or when the software was installed. I attempted to remove Bitdefender through normal uninstall procedures, but the software cannot be removed. I even tried uninstalling it in Safe Mode, yet the same restrictions remain in place. Because of the administrator password requirement, I cannot change settings, remove the software, or regain control over my system.
This situation has raised serious concerns regarding both my privacy and the security of my personal data. I am unable to determine whether the issue is caused by Bitdefender itself, an unauthorized installation, or another security-related problem. Regardless of the cause, I should not lose access to my own computer because of software that was installed without my approval.
I have attempted to contact Bitdefender through its support channels and customer service resources but have been unable to reach anyone who can provide assistance. Even if no payment was processed or subscription was created, the fact that software appears to have been installed on my personal device without my consent and cannot be removed is unacceptable.
I request the immediate removal of the Bitdefender software from my system, assistance in restoring my computer to its previous working condition, and a clear explanation regarding how this software was installed and why it is preventing me from accessing and managing my own device. If necessary, I am prepared to pursue all available legal remedies to protect my rights and personal data.
