The daily activity report shows "Event Type: Signature Set Update Failure" for one PC. Looking at the device in the console I find the following under error details and cannot find any documentation of error codes and how to troubleshoot. Any help is appreciated.
Error Code 50. Computer CPU incompatible with Behavioral Protection engine SSSE3 requirement.
Solved! Go to Solution.

Behavioral Protection also requires a CPU that supports the Supplemental Streaming
SIMD Extensions 3 (SSSE3) instruction set. See your CPU manufacturer’s
documentation for a list of processors that includes SSSE3. A signature set update failure with error code 50 will be in your Events list if the processor on a computer does not support SSSE3.
IMPORTANT! Some virtualization technologies, including Hyper-V and VMware, have
settings that can mask SSSE3 capabilities in the virtual machine even if the host CPU
supports them. See your virtual machine documentation to ensure these settings are
disabled to use Behavioral Protection.

I believe, it's about "either your CPU processor supports it or not". I don't think, we can do anything about it. I am not sure what changes can be done w.r.t CPU processors. By Disabling Behavioral Protection, we can get rid of the error but that's not a good idea.
You can download a tool CPU-Z (free download) on your system. Once you run it, it will show whether CPU supports it or not.
