Concerns about files created today in Library/Application Support and other areas

Dear Apple Support Community,

I am on a Mac mini. Latest software/OS. I am only end user knowledgable and have concerns about updates that were done on my hard drive today.

Is the following folder in Library/Application Support a legitimate Apple folder or malware?

/com.apple.TCC

Are the following files in /Library/Application Support/com.apple.TCC legitimate Apple files or malware?

TCC.db

REG.db

Are the following files in Library/Managed Preferences folder legitimate Apple files or malware?

com.apple.applicationaccess.plist

complete.plist

Are the following files in Library/SystemExtensions legitimate Apple files or malware?

db.plist

Thank you for your input and help.
