Has anyone seen this?
2017-04-12 20:29:14.106 macmnsvc(3328.3380) aac_service.Info: The process <C:\PROGRAM FILES\MCAFEE\AGENT\X86\MCTRAY.EXE>(3312) was blocked from accessing('CREATE' (1)) <AAC_OBJECT_SECTION:C:\PROGRAM FILES (X86)\QFINITI\QFINITI DESKTOP\QTRIGGER.DLL> via the rule <Sanitize McTray Process>
This isn't that unusual. There are lots of applications that try to inject DLLs into other processes. In this case, it looks like Qfiniti Desktop is injecting a DLL into the McAfee Agent tray app. McAfee doesn't like that, and stops it. It shouldn't be an issue.
Same answer than Tkinkead. this could be normal. i had this event quite a lot with 2 or 3 applications last year. Selft protection mecanism is rejecting the injection. Not a real issue.
