Sorry I have not experience with Anti-Theft, but I assume this behaviour is by design. If a thief gets your system, you do not want them to be able to disable/uninstall the program.
You may be able to get some help from online Support. At least they may be able to have some way to verify your ownership of the laptop and the program. Then, they may be able to offer you a solution to uninstall the product.
If you have not activated or registered the product, it should not be running and you could probably just ignore it. It would not affect system performance.
