Accidentally deleted 'usr/share' and 'usr/man' folders
I found folders in my Mackintosh HD folder that I was not familiar with. After recently detecting Malware, I panicked and deleted both the 'usr/share' folder and the 'usr/man' folder too. I'm concerned with how this may affect the operating system of my MacBook. Could someone please explain to me what I can do to either get these back (if that is at all possible) or whether this will be an issue for when I boot up the MacBook or anything else with the operating system. Thank you!
MacBook, macOS 10.15
