Anti-cheat: Security violation #00000010

I had not played Reach in two days and now that I tried to run it, I got the following error message. I restarted Steam and after that MCC started up normally without an error.

Easy Anti-Cheat
Game Security Violation Detected (#00000010)

I had no extra programs open and I did no changes to any file.
