First you need to figure out what happened?  At best you may have file
corruption.  at worst you've been hacked.

This isn't Windows.  Pieces of the system don't just disappear (that
doesn't really happen in windows either but that's the mindset of most
users and admins I have come across).

AFTER you figure that out it will dictate what measures you need to take.
