Microsoft issued Januarys cumulative security fixes for January 2018. These patches also include a range of important security fixes, including patches to SMB server. Microsoft require your Anti-Virus provider to certify compatibility with the patches. Some anti-virus vendors are using techniques to bypass Kernel Patch Protection by injecting a hypervisor which they use to intercept syscalls and make assumptions about memory locations. The January patches, and currently all future security patches, will not install unless antivirus vendors take action.”]
