US Patent 9058504 Anti-malware digital-signature verification

A self-protection application executes in kernel mode and manages access to processes and files related to an associated anti-malware application. The self-protection application monitors executing processes on the client device and detects the processes that are attempting to access files/processes related to the anti-malware software. These processes and files are verified by the self-protection application using digital signature authentication. Trusted processes such as those originating from the anti-malware software or other authorized programs are allowed access while other processes are restricted access.
