To remove rootkits you will often need a dedicated tool like Malwarebytes Anti-Malware. There is a rule that states that a rootkit running in the lower layer cannot be detected by any rootkit software running on layers above it. The kernel of the system infected by this type of a rootkit is not aware that it is not interacting with a real hardware but with the environment altered by the rootkit. Hypervisor (Ring -1): A firmware rootkit runs on the lowest level of the computer rings, the hypervisor, which runs virtual machines. A specific variant of kernel-mode rootkit that attacks a bootloader is called a bootkit. Kernel mode (Ring 0): A kernel mode rootkit live in the kernel space, altering the behavior of kernel-mode functions.
It uses relatively simple techniques, such as the import address table (IAT) and inline hooks, to alter the behavior of called functions. User mode (Ring 3): A user-mode rootkit is the most common and the easiest to implement. Depending on its method of infection, operation, and persistence, rootkits can be divided into the following types:
